Project of relevance: CINELDI


Abstract:

Charging of electric vehicles (EVs) on a large scale can cause problems for the grid. Utilizing local flexibility resources, such as smart charging, stationary battery, vehicle-to-grid applications, and local generation can be an efficient way to contain the grid challenges and mitigate the need for grid reinforcement.

Focusing on the INSPIRIA charging station located in Norway, this paper investigates the possibility of coping with imminent grid challenges by means of local flexibility. First, the potential grid challenges are estimated with the help of Monte Carlo simulations. Second, cost and performance for the various local flexibility sources are presented. Third, an analysis of the choice of battery, charging process, and battery economy are provided.

Finally, the paper discusses the optimal mix of flexibility resources to efficiently mitigate grid challenges at the INSPIRIA charging station.

Flexibility-Enhancing Charging Station to Support the Integration of Electric Vehicles

Written by: Iliana Ilieva and Bernt A. Bremdal (Smart Innovation Norway and University of Tromsø)

Published at: World Electric Vehicle Journal

Project of relevance: CINELDI


Abstract:

This paper discusses the Inspiria charging station facility in Norway, which enables various charging point operators to offer different charging systems for different purposes and needs.

The charging station can be considered a specific case of a shared economy, as users share the same infrastructure and much of the same space. By utilizing new technology and the differences in charging needs in an innovative way, the power requirements for charging can be controlled and the severity of high-load periods can be reduced – both within the charging station’s system and outside it.

Using historical traffic data from the Inspiria charging station’s area and Monte Carlo simulations, this study investigated the impact of charging on the grid – both in the current period and in the future. Attention was paid to the impact associated with the usage of superfast chargers. The possibility of containing grid disturbances through utilization of local flexibility was investigated.

Finally, we investigated the benefits that the charging station model brings to charging point operators and car owners. The research reported provides support for ambitions for accelerated roll-out and increased density of cost-effective charging points, the wider implication of which concerns the transition to fossil-free transport and the utilization of locally generated, renewable energy.

Published at: Applied Energy

Project of relevance: E-REGIO


Abstract:

This paper analyses a local electricity system (LES) comprising photovoltaic production (PV), a connection to the distribution network, local loads and an energy storage system (ESS). Given the flexibility of the ESS, the LES can provide a peak shaving service (PSS) to the grid operator based on the actual monthly power tariff.

The paper proposes a stochastic mixed-integer linear programming problem that maximises the expected operatingprofit of the LES midterm. Assuming a behind customers’ smart meter configuration, income is derived from selling the energy of prosumers to other external electrical areas. If the costs are higher than the income, the net profit will be negative, i.e. a net loss. The cost component of the objective function can be reduced through the management of local resources and by providing PSS to the distribution network operator to minimise the power cost of the monthly power tariff.

The model is tested for 720 h (considering a month of 30 days) in three cases: (i) without PV and ESS; (ii) with PV and ESS, where losses are 0%; (iii) with PV and ESS, where losses are 18%. Due to the monthly power tariff, the net loss of the LES is reduced through the optimal management of local resources when the ESS losses are lower than 18%. To assess seasonal implications about the LES, the 12 months of the year are also tested. The month of October indicated the highest peak shaving, while the lowest peak shaving depended on the ESS losses.

Implementing local flexibility markets and the uptake of electric vehicles – the case for Norway

Written by: Iliana Ilieva (Smart Innovation Norway), Bernt A. Bremdal (Smart Innovation Norway and The University of Tromsø)

Published at: ENERGYCON 2020

Project of relevance: CINELDI


Abstract:

Pursuing a common goal to mitigate climate change and contribute to a cleaner environment, end-users are taking over a more locally focused and sustainable lifestyle.

In compliance to this social trend, recent years have brought a strong push towards electrification of transport and in Norway the interest in electricity driven personal cars has become particularly high. To realize the environmental benefit associated with electric vehicles, however, it is necessary to have enough power generation from renewable energy sources and sufficient capacity in the grid. Yet, renewable energy sources are typically intermittent in nature and pose challenges to the power system, while investments in increased grid capacity can be very costly. In this respect, the usage of energy flexibility to alleviate such challenges can be an efficient solution.

This paper contributes to the research field by referring to eminent experiences from local market implementation trials in Norway – a country with a particularly high electric vehicle uptake rate. The paper pays focus to the flexibility opportunities stemming from charging of electric vehicles and to the “locality” as an important aspect of the market solution. Discussing key issues related to flexibility potential, local market design and implementation, the paper serves as a good reference point to support further steps towards local flexibility markets establishments.

Abstract:

With rising focus on integrating high shares of renewable energy into energy supply systems, the need to meet the viability of theses renewable sources becomes pressing. Apart from storing electricity in electro-chemical storage units, the concept of sector coupling could promise to provide the needed flexibility and storage capacities. A strong metric is needed to determine the viability and economic feasibility of different sector-coupled energy systems.

This conference paper presents an empirical method to develop a list of key performance indicators (KPI), as a direct adaption of the KPI of energy system with a single energy vector is not always possible. The list was developed based on a stakeholder workshop within the H2020 research project E-Land.

We propose the introduction of three new indicators for the evaluation of sector-coupled energy systems, namely degree of autonomy, levelized cost of energy and degree of sector coupling. A sector-coupled case study is evaluated to validate the performance of such new indicators while proving their utility to better assist decision-making.

A Framework for Offering Short-term Demand-Side Flexibility to a Flexibility Marketplace

Written by: Stig Ø. Ottesen (eSmart Systems and Smart Innovation Norway), Martin Haug and Heidi S. Nygård (Norwegian University of Life Sciences)

Published at: Energies

Project of relevance: Independent research


Abstract:

The decarbonization of the power sector involves electrification and a massive deployment of variable renewable energy sources, leading to an increase of local transmission congestion and ramping challenges. A possible solution to secure grid stability is local flexibility markets, in which prosumers can offer demand-side flexibility to the distribution system operator or other flexibility buyers through an aggregator.

The purpose of this study was to develop a framework for estimating and offering short-term demand-side flexibility to a flexibility marketplace, with the main focus being baseline estimation and bid generation. The baseline is estimated based on forecasts that have been corrected for effects from earlier flexibility activations and potential planned use of internal flexibility. Available flexibility volumes are then estimated based on the baseline, physical properties of the flexibility asset and agreed constraints for baseline deviation.

The estimated available flexibility is further formatted into a bid that may be offered to a flexibility marketplace, where buyers can buy and activate the offered flexibility, in whole or by parts. To illustrate and verify the proposed methodology, it was applied to a grocery warehouse. Based on real flexibility constraints, historic meter values, and forecasts for this use-case, we simulated a process where the flexibility is offered to a hypothetic flexibility marketplace through an aggregator.

Written by: Iliana Ilieva (Smart Innovation Norway) and Steven A. Gabriel (University of Maryland)

Published at: Journal of energy markets

Project of relevance: Independent research


Abstract:

The Nordic end-user market for electricity has been subject to significant changes. The energy authorities within the Nordic countries have been intensively working to create a common electricity retail market that is fully operational, and all customers have had smart meters installed in 2019.

These changes are of particular concern for the suppliers of retail electric power as competition will increase and the retail products and offers related to the smart grid and the specific customers’ needs will gain importance. With the help of a mixed complementarity problem formulation that describes a simplified market setting with two competing retailers, we analyze the impact of the pending market changes on electricity retailers’ price markup and profit.

About the book

Introduces readers to micro and local power markets and their use for local initiatives, grid integration, and future applications.

This book provides the basis for understanding micro power markets, emphasizing its application for local initiatives, the grid integration of renewable-based generation, and facilitating the decarbonization of the future electrical networks. It gives readers a comprehensive overview of the market operation, and highlights the basis of the design of local and micro markets.

Micro and Local Power Markets starts by covering the economics and basic principle of power markets, including the fundamentals of the power trading (for both wholesale and local markets). Following a definition of both micro and local (technical and economic aspects) power markets, the book then looks at the organization of such markets. It describes the design of those power markets, isolated from the wholesale markets, and examines the methodologies of the interaction between these power markets and wholesale markets. The book also presents cognitive business models for micro and local power markets, as well as the regulatory issues concerning them.

Published at: 1st Nordic Conference on Zero Emission and Plus Energy Buildings, 6-7 November 2019

Project of relevance: E-REGIO


Abstract:

With increasing share of distributed renewable energy resources in the grid and arising energy consumer awareness on environmental challenges, new market models are sought where energy can be traded in an efficient and end-user centric way. This trend, together with the increasing consciousness on the benefits of local consumption and production has given rise to an increased focus on local energy market structures.

Within the E-REGIO project, funded through the ERA-Net Smart Grid Plus initiative, local energy markets have been paid particular attention. This paper discusses opportunities associated with local energy trading, as verified through the E-REGIO local energy system pilot – Skagerak EnergiLab in Norway.

Embracing, among others, local loads, energy storage system, PV generation and a large consumer (stadium facility), the pilot-based simulations have produced some useful insides on the implementation of local energy markets and have helped collect learnings that can be of benefit for future local energy market establishments.

Multi-vector energy optimization tools for energy islands

Written by: Sanket Puranik, Heidi Tuiskula and Iliana Ilieva (Smart Innovation Norway), Ferran Torrent, Joan Colomer and Joaquim Meléndez (University of Girona)

Project of relevance: E-LAND


Abstract:

Synergies between multiple energy vectors can support decarbonization of local energy islands and, at the same time, relieve stress from the electricity grid. Multi-vector energy systems offer flexibility to integrate variable and economic local energy generation. However, the implementation and operation of multi-vector energy systems face technical, societal and business-related challenges. This paper identifies these challenges and proposes different tools to tackle them.

These tools are to be developed in the E-LAND project funded by European Union under the H2020 scheme. Special focus of the paper is on developing a method for optimal planning and operation of multi-vector grid considering robustness. Another novelty of technical tool lies in making scheduling decisions on long-term and short-term storage considering demand response as flexibility resource.

By combining technological, societal and business tools, the project expects to create multi-vector energy systems accepted by citizens and with viable business model.

Abstract:

Different technologies aiming to digitize the distribution grid are being developed within research and innovation (R&I) projects. To unlock the true potential of the digital technologies in the distribution grid, novel solutions must be coupled with new business models. However, creating and validating new business models in the early phase of the innovation process and during the relatively short period of R&I projects is a challenge.

This paper presents a methodology to create and validate new business models using business model canvas (BMC) and a stakeholder innovation group (SIG). The methodology is currently being tested in the RESOLVD project funded by European Union under the H2020 scheme.

Abstract:

As the challenges associated with sustainability, urbanization, life quality and demography become more imminent, companies are adapting to the changing requirements by means of revised strategic approaches. Thus, enterprises are increasingly deviating from the traditionally absolute priority of maximizing total return for shareholders. While this priority is still important, businesses are also looking at the total societal impact (TSI), which represents a collection of measures and assessments that incorporate the economic, social and environmental impacts of their products and services.

This paper focuses on the compound influence that TSI may have within the energy domain. In particular, the business opportunities resulting from the Horizon 2020 funded project INVADE are being discussed but seen from the perspective of a socially responsible corporate strategy.

Referring to discussions, analyses and undertaken initiatives, this paper concludes that business models which incorporate environmentally friendly, local and social and fair energy are capable of accelerating business growth for the concerned companies.

Published at:
 International Journal of Hydrogen Energy, Volume 42, Issue 44, 2 November 2017, Pages 27269-27283


Abstract:

A 50 kW PEMFC pilot plant has been operated 4400 hours using hydrogen originating from a sodium chlorate production process after standard industry purification processes were applied.

The first stage of the fuel cell system operation was performed using anode gas recirculation, while in the other stages an open anode configuration was applied. The fuel cell system did not show extensive degradation despite the low quality of the hydrogen and frequent shut-downs. The average degradation rate was 2-3 microvolts per hour at low and medium currents (10-150 A).

The main causes for any unreliability were found to be hydrogen supply side system components, namely pressure reducers and valves. Recommendations are given for the improvement of both PEMFC power plant design and operation for industrial hydrogen applications.

Published at:
2016 IEEE International Energy Conference (ENERGYCON)


Abstract:

This paper presents a novel method for determining plug-in Elecric Vehicle (EV) traffic and associated recharging needs based on an ACO (Ant Colony Optimization) method. The method is used to analyze traffic patterns and to determine their impact on the local grid and the design of charging stations.

The research reported here also supports the design of a portfolio of Charging Stations (CSs) across a limited geographical area and use this to determine the required capacities of each station. An empirical basis for the research presented has been gathered from Norway where the number of EVs are growing fast and where use of EVs for different purposes, including long-range driving, are becoming very pronounced. The research presented also shows how demand for charging at different times can be determined.

This lays the foundation for estimating peak loads in the local grid due to EV charging. For the individual driver the system presented can be used to find preferred routing under different circumstances such as traffic congestion.

Abstract:

This paper defines a day-ahead micro-market structure and illustrates its capability of increasing distributed energy resources’ integration. This micro-market mimics in the distribution level the structure of the current European day-ahead markets and their rules to introduce competition, and is based on the social welfare indicator.

Micro-markets could overcome two major challenges of pool markets: they could consider the distribution network to ensure feasibility of the matched configurations and they could handle a high penetration of renewable energy without generation costs. A micro-market is controlled and supervised by the micro-market operator who executes the auction algorithm.

This paper exposes a state-of-the-art about micro-markets, proposes a structure and a set of rules, and shows micro-market’s behaviour in a case study. The results show that with under-sized distribution networks the micro-market can effectively improve the social welfare with respect to other simpler approaches.

Abstract:

The coming up decarbonized European electricity system with the proliferation of distributed and renewable energy production sources have created a global surge of interest in local electricity markets for neighbourhoods. Moreover, the European electricity system in 2050 will have millions of prosumers, electric vehicles and storage units willing to provide energy and flexibility that will be capitalized in distribution grids.

Our vision is an integrated wholesale market with geographical distributed multiple local markets. This topic has caught the attention of policy makers, regulatory bodies and researchers alike.

In this paper, we present some of the results on local market design and operation that has been developed in Work Package 6 of EMPOWER Horizon 2020 project. We propose a new market player role titled Smart Energy Service Provider (SESP) that manages the local market for energy, flexibility and other services. SESP provides an ICT trading platform for local players in the distribution grid such as DSO, prosumers, consumers, storage owners, distributed generators and others to participate in various local markets.

Bremdal (Smart Innovation Norway/UiT)

Published at:
 Energies 2018, 11(4), 822


Abstract:

This paper presents a general description of local flexibility markets as a marketbased management mechanism for aggregators. The high penetration of distributed energy resources introduces new flexibility services like prosumer or community self-balancing, congestion management and time-of-use optimization.

This work is focused on the flexibility framework to enable multiple participants to compete for selling or buying flexibility. In this framework, the aggregator acts as a local market operator and supervises flexibility transactions of the local energy community. Local market participation is voluntary. Potential flexibility stakeholders are the distribution system operator, the balance responsible party and end-users themselves. Flexibility is sold by means of loads, generators, storage units and electric vehicles.

Finally, this paper presents needed interactions between all local market stakeholders, the corresponding inputs and outputs of local market operation algorithms from participants and a case study to highlight the application of the local flexibility market in three scenarios. The local market framework could postpone grid upgrades, reduce energy costs and increase distribution grids’ hosting capacity.

Abstract:

Global markets are experiencing a paradigm-shift due to the introduction of new business models. In addition to this, the shift towards prosumers, customer friendly regulation and services and decentralized energy markets are now making their way into the energy markets. To address these challenges the Horizon 2020 project named INVADE is developing technology platforms and platform based business models in parallel to address these challenges.

Our approach has been to study the effects of platform based business models in other industries, what platform based business models look like, how they work, and how they are currently developed in energy markets.

The next step has been to confront the technical work packages and the pilot owners in the project to align theory with practice. This has produced tangible outcomes.

Abstract:

The purpose of this paper is to describe the roles, services and relationships that a local market would encompass, and the type of market interactions that should take place in it. The local market place constitutes an arena for a new business role – the smart energy service provider, which represents the entity with the most central functionalities with respect to local market operation.

The local market is described as consisting of three key elements of brokerage/sale: energy, flexibility and other services. Three alternative market settings are considered: islanding mode, interaction with the wholesale market and a third one where other market agents (aggregators/retailers) carry the interactions with the wholesale market.

Finally, the paper specifies the relationship between the smart energy service provider and the various local market actors and provides a clarifying user case.

Abstract:

The objective of this study is to evaluate how PV-oriented prosumers can offer flexibility to the Distribution System Operator (DSO). The different cases focus on the customer and changes on the customer side that will benefit both the customer and the distribution grid. (Actual tests of services delivered to the DSO have not been performed.)

The study also highlights the importance of being proactive about the placement of roof top panels near the loads in the grid for a better balance between PV-output and loads at the terminal points in the grid. This approach demonstrated the secure operations of the grid well below the capacity limits and yield better rewards for the prosumer.

In this study, storage options at the prosumer side are also considered and both technical and economic aspects are analysed. Special emphasis is placed on the impact of power tariff structures that include capacity considerations.
