NETFFICIENT Report Summary

Project ID: 646463
Funded under: H2020-EU.3.3.

Periodic Reporting for period 1 - NETFFICIENT (Energy and economic efficiency for today’s smart communities through integrated multi storage technologies)

Reporting period: 2015-01-01 to 2016-06-30

Summary of the context and overall objectives of the project

NETfficient is tackling one of the most pressing challenges of the energy market, as the availability of renewable energies is not considered the sole problem, but its storage and distribution methods due to the time-shift between availability of renewable resources and demand peaks. The project aims at deploying and demonstrating local storage technologies as well as developing the necessary ICT tools to exploit the synergies between energy storage solutions, smart grid and citizens. The demonstration in the real environment on the German island of Borkum in the North Sea will be driven by five use cases covering a wide range of applications and functionalities including low voltage and medium voltage scenarios. By focusing on renewable energy sources to feed the energy demand on the island, the project will help to reduce carbon emissions as well as the dependency on fossil fuels, empowering households, districts and citizens to adopt a sustainable and clean energy supply. The Island of Borkum will be enabled to further realise its goal to become energy autarkic.

The decentralized energy generation coupled with energy storage systems and the smart energy software platform (being connected to the electric grid and fed by real time data and information) will empower citizens and businesses to become active prosumers. This means that all stakeholders, from policy makers and municipalities to the citizens, will be involved in the energy value chain for a better living and working environment.
Thus, the project aims to develop solutions adaptable to small towns, big cities and isolated and low connected areas in a feasible and financially viable way. It will provide a complete sample of a Smart Energy City where the main “use cases” can be transferred to any smart city. It is NETfficient’s target to enable the good exploitation of existing renewable energies on Borkum island at any time by developing the missing link between mass uptake of storage and energy management technologies. This means that clean and sustainable energy will be stored in the island’s electric grid when it is available, to be distributed in a later point in time, when there is an energy demand for it.

The main objectives of the project are to develop and test in a real environment use cases of energy storage systems with a high replicability and profitable business cases. These objectives will be achieved by developing a central Energy Monitoring System that will be used energy companies to manage the energy of their associates´ storage devices. Besides, the project will provide DSO with control systems to integrate management and decision support tools that enable the integration of renewable generation and storage systems into grid.

Finally, by participating in different working group, NETFFICIENT directly contributes to identify barriers to the deployment of distributed storage technologies and make new proposals to overcome them.

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

During this first phase of the project, most of the technical activities conducted aim to define and set up the framework and foundation of the solution at different levels (electrical, software, etc.). This enabled the integration of all the components in an optimized and feasible way: Storage technologies (Hybrid Energy Storage System, Li-ion batteries, Second Life Electric Vehicle Batteries, Super capacitor + Li-ion batteries), inverters, smart-meters, renewable generators, monitoring and controlling systems, energy software management platform and so on, ranging from MV to LV.

The collection and analysis of all technical requirements and specifications (ICT, electrical, etc.) to be taken into consideration along the project have been undertaken. In particular, the overall architecture and grid design at both LV and MV level have been performed. The MV and LV storage systems have been designed including the communication outline between components. The LV inverters have been designed and adapted to the optimal PV-panel-configuration. The MV HESS components have been built. The interfaces and data to be interchanged have been defined. The Energy Management Software Platform (EMP) requirements analysis and specification definition has been conducted and collected, the products and software to be used on the development of the software platform, the systems architecture of the EMP, the functional design of the software platform, the algorithms, rules and prototypes and the EMP interfaces have been defined. The protocols and interfaces to allow the communication between each pair of the elements have been defined. In addition, a detailed description of the five use cases that will allow to test the solution have been carried out.
The LCA and LCC analyses were implemented. Besides, all the measures needed to ensure compliance with ethics regulations and laws were put in place.

At management level, all scheduled milestones (Project website release and social media connection under the corporate identity, Specifications defined, Storage & Energy Systems Designed, Uses Cases Defined, Energy Management Platform Systems designed, Integration Systems Designed) have been met on time as well as all scheduled deliverables.

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)

The project NETFFICIENT will enable to exploit the synergies between energy storage solutions, smart grid and citizens to propose a solution to solve the problem regarding the time-shift between availability of renewable energy and demand peaks through innovative local storage technologies as well as smart ICT tools. The decentralized energy generation coupled with energy storage systems and the smart energy software platform (being connected to the electric grid and fed by real time data and information) will empower citizens and businesses to become active prosumers, achieving important strategic competitive advantages¸ including cost saving due to optimal coordination between renewable energy generation and consumption as well as higher network stability.

Overall improved management and control of all devices included in the proposed solution will have a positive impact on the everyday life of European citizens, leading to increased energy and resource efficiency with smaller carbon footprints as well as the dependency on fossil fuels and more efficient use of renewables, fully in line with the “Smart Sustainable Growth” objective of the H2020 EC strategy. This means that clean and sustainable energy will be stored in the island’s electric grid when it is available, to be distributed in a later point in time, when there is an energy demand for it.

The project will empower households, districts and citizens to adopt a sustainable and clean energy supply and involve different type of stakeholders (policy makers, municipalities, citizens and so on) in the energy value chain for a better living and working environment.

The project will set the basis for developing solutions adaptable to small towns, big cities and isolated and low connected areas in a feasible and financially viable way, providing a complete sample of a Smart Energy City where the main “use cases” can be transferred to any smart city.
