The following article describes results of MOEEBIUS H2020 project which introduces a Holistic Energy Performance Optimization Framework that enhances current (passive and active building elements) modelling approaches with advanced user behaviour modelling and machine learning technologies to create an innovative suite of end-user tools and applications.
The project NOBEL GRID, funded by the European Union’s Horizon 2020 research and innovation programme, will provide advanced tools and ICT services to all actors in the Smart Grid and retail electricity market in order to ensure benefits from cheaper prices, more secure and stable grids and clean electricity. These tool and services will enable active consumers’ involvement, new business models for new actors and the integration of distributed renewable energy production.

The FLEXICIENCY project aims to demonstrate that the deployment of novel services in the electricity retail markets, such as advanced monitoring, local energy control and flexibility, can be accelerated thanks to an open European market place for standardised interactions among electricity stakeholders within and across borders. This will open up the energy market to new players at EU level.
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 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.
INERTIA project addresses the "structural inertia" of existing Distribution Grids by introducing more active elements combined with the necessary control and distributed coordination mechanisms. To this end INERTIA will adopt the Internet of Things/Services principles to the Distribution Grid Control Operations.
The S3C project aims at developing ready-to-use tools for long-term end-user engagement by addressing the end-user in his three roles as smart consumer, customer and citizen. An interactive toolkit website will be developed throughout the project. The first S3C deliverable (D1.1) describes a variety of insights on end-user engagement in smart grid projects from a theoretical and from an empirical perspective. From the theoretical perspective, we found that various theories exist that can be used to frame and analyse consumer behaviour.
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.
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 Smart Watts project was initiated within the German E-Energy programme on the development and testing of Smart Grids (2008 – 2021). The project consortium‘s declared goal lay in the design and implementation of an unbundling compliant information and control model for the energy system that supplies all market participants with near real-time data on generation and consumption of energy. That way, an intelligent supply management is enabled by a comprehensive control and optimisation of energy portfolios.
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.
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.
Integrating renewable energy sources into the distribution network (SGMS project) requires intelligent network control solutions that involve producers and consumers to use the existing infrastructure more efficiently and to increase the hosting capacity of the network to handle energy flow from decentralized renewable sources. For this purpose, an internationally premiered prototype was developed for medium voltage networks, out of which a product that is suitable for general use can be created. The prototype has shown that an increase in generating capacity in the critical section of the network in the Demo Region by approximately 20 % is realistic. A functional solution for voltage control in low voltage networks was also developed and implemented in the Model Community of Köstendorf. Due to the numerous stakeholders and applications that must be taken into consideration at this level, it is extremely important to develop rules for how they will interact.
Smart Infrastructure Salzburg also includes intelligent system integration for electromobility. In this area of application, the effects of a high concentration of electric vehicles on the power grid were examined (simulation of EV charging) and a concept for interaction between the power system and its users was developed. Since widespread congestion on the low voltage distribution grid is to be expected when market penetration reaches 25 % to 40 % depending on the charging strategy, the development and implementation of adaptive charging is recommended. Until this concept can be put into place, three-phase charging with low charging capacities can prevent grid overloads. Vehicle-to-grid delivery of electricity is not economically feasible due to current market conditions since present costs are around twice as high as the economic benefits.
The ADDRESS system has been tested in Italy , as shown in the diagram below, specifically focusing onto the validation of the upstream part of the ADDRESS chain, going from Active Demand buyers to the aggregation platform, with a focus on the DSO and related distribution network operations for a large MV network, and on the effect of Active Demand (AD) visible at the High Voltage level.
An important output of the ADDRESS project is the provision of a series of recommendations towards the main key players of the demand response game: aggregation functions, consumers, system operators, deregulated players, standard committees and regulators, technology manufacturers.
