The lighthouse NETfficient, supported under the “Societal Challenge of Low Carbon Energy" within the European Research and Innovation Programme Horizon 2020, will implement “Energy and economic efficiency for today’s smart communities through integrated multi storage technologies” on the German island of Borkum in the North Sea.
ELSA aims at implementing and demonstrating innovative solutions for energy storage integrating low-cost second-life electric vehicle Lithium-ion batteries and other direct and indirect storage options, including heat storage, thus facilitating the local energy management of buildings, districts, and industrial complexes, as well as the direct local use of electricity generated from intermittent renewable energy sources.
The strategic goal of BESOS is to enhance existing neighbourhoods with decision support system to provide coordinated management of public infrastructures in Smart Cities, and at the same time provide citizens with information to promote sustainability and energy efficiency.
TILOS demonstrates the optimal integration of local scale battery storage in a smart island microgrid and challenges the interplay between storage, DSM and interconnection. By encouraging public engagement, TILOS addresses the social aspects of community storage and seeks for the development of novel business models.
Estfeed project built a software platform capable to integrate many data sources and to provide appropriate services to convert these data into valuable information for energy flexibility management, energy efficiency, audit and benchmarking.
The I3RES project was financed by the European Commission under the Seventh Framework Programme and more specifically the call ICT-2011.6.1 on Smart Energy Grids. As a result, the I3RES Management Tool was developed.
The E-DeMa project in the model region Rhein-Ruhr was initiated in the framework of the German lighthouse project initiative E-Energy (2008-2012) and aimed at designing ICT-based solutions enabling the intelligent utilisation of all resources at the model region’s disposal. Additionally, the project targeted the optimisation as well as the integration of the energy system starting from generation to storage, up to the distribution of electricity leading to an efficient final consumption through new services based on metering data and energy management services.
The research-and-development project MeRegio in Goeppingen and Freiamt was designed and implemented within the E-Energy programme (2008 – 2012). It targeted an ICT integration in all parts of the energy value chain in order to meet the demand for efficient, yet decentralised energy systems.
The E-Energy project Model City Mannheim (“moma”), which was designed and implemented within the German E-Energy programme (2008 – 2012 ) developed an energy system architecture based on the natural cellular structure of objects and thereby enabled a multi-field-solution for the utilization of renewable energy sources to the largest possible extent and the Integration of small-scale storage units.
In the Harz region in Germany, a model project with a strong regional focus was developed and implemented within the lighthouse Smart Grids programme E-Energy (20098- 2012).
Eighteen partners as well as four associated firms – many of them settled and active in the region themselves including several small-sized regional utilities and SME’s with a focus on new energy services and products - constituted the RegModHarz consortium. Together, the consortium implemented a virtual power plant considering the integration of DER (suppliers), consumers, and the Integration of small-scale storage units.
Small and medium sized decentralised generation units as well as commercially used consumption applications can play a key role in a future energy supply system. This is especially true for decentralised generation units: they don’t need to rely on the further construction of transmission network capacities since they are situated close to the actual demand side. In addition, from a physical point of view, the total capacity of generation from this type of generation unit can be multiplied in the future.
The project Model City Mannheim has designed a “cellular control concept” for electricity grids that supports centralized as well as regional connectedness and coordination mechanisms between different parts of the network. It serves to create regional market and grid mechanisms and provides for information security and privacy. It focuses on small-sized, connected, yet self-controlled structures instead of one central network monitoring and management system.
The E-Energy model region eTelligence project in Northern Germany has set strong emphasis in including commercial customers into their field trial and making their flexibility available for new business models. The approach was indeed very successful so that EWE AG (Northern German utility) has developed a product called intelligent load manager based on the experience gained in eTelligence and is currently contracting an increasing number of commercial customers in their supply region for the new load management mechanism.
The E-Energy model region MeRegio, located in a rural distribution grid area that is characterized by a high share of installed DER units, took on the challenge of finding an unbundling-compliant way of utilizing residential and commercial consumption flexibility for distribution grid oriented services. They developed the so called MeRegio Hybrid Model or priority signal that was designed in analogy to the federal grid office’s Grid Operation and market sphere – a market model based on traffic light logics.
The consumer behaviour with regard to adapting their consumption to new price signals has been tested and controversially discussed for years. As a result, the E-Energy model region Model City Mannheim (moma) had declared customer research as one of their main focus areas. The idea of the complex tariff system fully deployed during the third field trial was not only to transfer changing energy prices from e.g. the EPEX spot market or the availability of renewable energy on the local distribution grid, but also to deliberately test price spreads and thus the price elasticity of customer decisions made on electricity consumption.
Virtual power plants control and market generation, storage and consumption flexibility can take over one of the central tasks to be fulfilled in a future, increasingly decentralized energy system. The so-called aggregation process implies the orchestration of a diversity of generation, storage and consumption units into a virtual, interactive construct (unit pool), which can be controlled by a system service provider in a bidirectional manner.
Networks in Germany do not only face structurally but also temporally different challenges. The former German Ministry for Economics and Technology (now Ministry for Economics and Energy) has instated a stakeholder working group called Smart Grids and Meters that includes several stakeholders from all E-Energy projects (E-DeMa, eTelligence, MeRegio, moma, RegModHarz and Smart Watts) and an accompanying research team that offered their project results to find new approaches to deduce an equilibrium between market and grid-dominated actions in a Smart Grid infrastructure.
In DISCERN, DSO’s current system architecture (SCADA/ DMS/ OMS/ NIS/ EMS/ MDMS) for distribution network operations and their interfaces with station and enterprise zones were analysed.
The modification of load profiles coming from the demand response market may impact the system security and/or the power quality of supply. Coordination is therefore a must between the various market players.
