STORY Report Summary

Project ID: 646426
Funded under: H2020-EU.3.3.

Periodic Reporting for period 1 - STORY (STORY- Added value of STORage in distribution sYstems)

Reporting period: 2015-05-01 to 2016-04-30

Summary of the context and overall objectives of the project

The main objective of STORY is to show the added value storage can bring for a flexible, secure and sustainable energy system.

This will be achieved by showing the inter-relations between technologies and stakeholders as well as the potential and impact of policy and regulation.

The future European grid has to serve a diverse and mixed landscape of users in a situation of mixed rules and responsibilities depending on the policy and regulatory choices that will be made. Challenges include high penetration of renewables, bi-directional flows of different energy vectors, growing number of users and requirements for higher security. The European commission wants to strengthen the position of the EU energy industry, including those players active in producing solutions for security of supply, increased share of renewables and grid stability. The advances in ICT technology, intelligent control algorithms, inverter and storage technologies provide strong tools to cope with these challenges.

Given this context, STORY focuses on providing relevant and wide-covering demonstrations that serve as input for a thorough and transparent analysis on what the impact of storage can be for the involved stakeholders. Storage is considered as a means, while not neglecting other competing technologies that could provide a similar or complementary functionality.

The actions that the 18 members from 9 European countries in STORY consortium are going to take in a 5-year project bring a valuable contribution to turn these challenges into opportunities. They will not only develop the most viable storage and ICT solutions for the demonstration sites, but they will also analyse the impact of large penetration of the technologies through simulations, analyse the effect of policies and regulations to the business opportunities of storage related industry and communicate the findings to wider community through systematic strategies for impact creation.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

Efforts on the 1st period were focused on defining the main grid challenges to be addressed by storage solutions, specification on the requirements for the hardware and software elements that will be applied in the demonstrations and simulations, and on defining a common vocabulary and shared vision of the goals for the project. On the other hand, the installations on the demo sites were realised or preparatory work was conducted on the sites. The IT Architecture has been defined and optimized for each demonstration site and work has been done to develop these IT platforms. The partners started also the work on defining the measurement protocols and the related Key Performance Indicators. One significant result was the definition of a three level architecture for the control system. The grid simulation scenarios were chosen based on thorough studies of the local environment and availability of data. The definition of the business models started in co-operation with the other LCE6 to 10 projects (in frame of the BRIDGE co-operation). The dissemination activities started by creating a communication plan and communication style. First newsletter (together with other LCE6 to 10 projects), brochure and educational movie were published, and the project was presented at international conferences. The consortium studied the ethics requirements for the different sites and prepared the neccessary documents and templates for answering these requirements. In general, the work progressed towards the main Scientific and Technological goals, although there were some delays caused by mainly external circumstances, that could not be foreseen in the preparation phase. The delays have caused needs for changes in the timing of the different components in the project, and these are suggested as amendments after the periodic reporting is finalised.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

In order to make a clear and visual overview of the ambition and novelties in each demonstration and how the demonstrations complement one another, radial charts are provided in attachment. The level of innovation is indicated from a scale of 0 to 5, with 5 being the most innovative. The different aspects they are scaled on are: business model, process approach, technology at component level, system of technologies and control of component and/or system. The charts are supported here by a structured ambition overview, covering all aspects of the STORY project.

1) Ambition level regarding demonstration technologies
The attached charts show that the storage technologies used in the different STORY demonstration sites include established types of resources (TRL9), but also newer technologies still requiring to be validated in real on-site operation (TRL5). STORY will utilize several technologies with various technology readiness levels such as a smart hardware solution for black-outs in a demonstration site, a new heat storage with a state-of-charge measurement system, a large scale isothermal compressed air storage, a new type of flow batteries or an innovative thermal grid mixed high-low operation. Although the technologies used in the demonstrations may be business as usual, the way they are used in the demonstrations is clearly beyond the state-of-the-art.

2) Technical integration
The technological ambition of STORY is strongly related to the novel ways of using and integrating existing and partly new technologies with the help of ICT tools for the control and management of the local networks. STORY will go beyond the building level in the management of the energy flows to demonstrate the benefits of integrating storages in the grid, taking advantage of the innovative management of different energy vectors needed on the site. STORY will implement new and existing technologies and integrate them using the existing techniques and procedures and developing new ones where needed. STORY will innovate by pushing the limits of the integration by combining different technologies together and by challenging the existing algorithms to provide different and better services. In two demonstration sites, STORY will implement systems that have never been implemented before. They are a building level micro-grid control with a photovoltaic system and an inter-seasonal thermal storage for one and a large thermal storage unit combined with a wood burner and an organic Rankine cycle plant. STORY will also innovate by proposing a control platform making the link between the storage resources and their control systems on one hand and the different energy market and energy network needs on the other.

3) Modelling
The multi-energy modelling tool Apros will be used in STORY for modelling the sites, including the ones with more than 1 energy vector. The simulation models are calibrated and verified by the demonstrations. The simulations will enable much better coverage of different options, situations and scenarios than the demonstrations as such. The simulation models can also be used to support the development of the forecasting and optimization models for the resources including storage. They will also contribute to the extrapolation task, where the opportunities created by wider penetration of storages in the grid will be studied.

4) Value chain
STORY will go into the depths of the installation of storage technologies at the different levels of the power value chain. Storage will be included at the building, district and low voltage network levels. The analyses will focus on their own level (for example, how can storage technologies be used to increase the penetration of PV production), but include the bigger picture (can the same set up also increase comfort, reduce overall energy bills, provide services to energy market and network actors). The larger scale levels of the value chain, such as power markets and high voltage electricity networks will be considered and the impacts of STORY will be modelled. By doing so STORY will make the link with other projects in the group of related topics on Competitive low-carbon energy (LCE6-LCE10). The analysis of the impact of storage technologies on a large-scale based on actual local implementation and simulation brings a new approach to the problem which is usually approached starting from a large-scale point of view.

5) Strong and open cooperation
There has been strong efforts by the Commission to encourage cooperation between different projects with related themes. STORY will take a radically new approach for the exchange of knowledge between the projects with related projects. STORY will be fully integrated in the European research environment by sharing information between the partners about recent research projects on the relevant fields. The cooperation is structured in the setup of a Projects Council and the integration in the workplan of communication with the other projects on specific aspects such as the measurement methodologies.

6) Communication technologies
STORY will develop communication platforms for the demonstration sites, including the information and control exchanges and will integrate the measuring and monitoring in the platforms. The performance and other quality of service properties of the communication technologies will be analyzed with respect to the requirements of the demonstration sites. A strong emphasis is put on potential savings through improved interoperability.

7) Regulations and policies
The fundamental idea of STORY is to provide strong evidence on the opportunities provided by the intelligent integration of storages in the grid and the benefits that can be obtained. This requires also critical study of the current regulatory and policy framework and other preconditions for the business. STORY will provide a comprehensive guide for policy makers and regulators showing the pros and cons of different approaches to the integration of storage technologies and providing guidelines to achieve different objectives related to energy storage. The added value of STORY is to include the technical and the economic aspects of energy (heat and electricity) storage, based on actual implementation and extrapolation from the demonstration results and experiences.

8) Competitiveness for the business actors
The increased competitiveness of European industries in the area of storage technologies requires in addition to the thorough analysis of the preconditions, also a development of competitive business models that are carefully designed to meet the needs of the clients. All the components of the business model needs to be handled in a systematical way to create the most competitive model for a certain market and product or service. STORY will provide a transparent and clear overview of the impact regulated or market driven roll out of storage will have for each of the stakeholders.

During the frst reporting period, the impact was created through dissemination about the general advantages of storage technologies, e.g. through an informative movie aimed at the pubilc at large. The co-operation with the other LCE6 to 10 projects was also started and formulated during the first period. The definition of the simulation scenarios will feed in the discussion of the impact of different regulations and policies.
