The project SmartNet aims at comparing different architectures for optimized interaction between TSOs and DSOs in managing the purchase of ancillary services (reserve and balancing, voltage regulation, congestion management) from subjects located in the distribution segment. An ad hoc simulation platform is built up over three layers (physical network, market and ICT) in order to simulate three national cases (Italy, Denmark, Spain); this simulation platform is then implemented in a full replica lab, where the performance of real controller devices is tested. Three physical pilots are also developed to demonstrate modalities for exchanging monitoring signals between transmission and distribution networks and flexibility services that can be offered by entities connected to distribution by exploiting thermal inertia of indoor swimming pools and distributed storage facilities of radio-base stations used for telecommunication.
The SMARTWATER project will generate some investigation tools to assess the feasibility of the rehabilitation of end-of-life quarries and mines into medium-sized PHES units. The project implements a holistic approach encompassing legal, environmental, economic, hydraulic, electro-mechanical, and geological aspects. The reservoir capacity and hydraulic head of most of the sites under consideration are around a few hundreds of thousand cubic meters and a few dozen meters respectively. Economic feasibility includes assessment of the cost reduction opportunities offered by such site configurations (widespread in Wallonia) and the exploration of innovative multi-service (DSO and TSO) exploitation strategies in the context of an increasing intermittent production.
RealValue is a €15.5m European Horizon 2020 energy storage project, which aims to use a combination of physical demonstrations in Ireland, Germany and Latvia along with innovative modelling techniques, in order to demonstrate how local small-scale energy storage, optimised across the whole EU energy system, with advanced ICT, could bring benefits to all market participants.
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.
ENERGISE is a research project of the EU Commission established to perform an analysis for smart grid communication infrastructure together with the different parties on governmental, industrial, DSO and TSO side. The main focus is on identifying the different factors which determine if a dedicated or shared communication infrastructure should be used and aid the decision-making for solution deployment. At the same time the different parties are brought together during workshops and on-site visits in order to enhance the interdisciplinary communication and exchange of knowledge.
The EcoGrid EU project develops and demonstrates a near real-time market providing a demand response market mechanism concept and allowing for services provided by DER to TSOs (feeding more generally the potential services provided by DSOs to TSOs).
Started in November 2011 for a duration of 51 months, this FP7 project lays the groundwork for the development of tomorrow's electricity grids. It will test the potential of smart grids in areas such as the integration of DER, the integration of small-scale storage, the integration of electric vehicles (EVs), grid automation, energy efficiency and load shaping.
REserviceS (Economic grid support from variable renewables) is the first study to investigate wind and solar based grid support services at EU level. It provides technical and economic guidelines and recommendations for the design for a European market for ancillary services, as well as for future network codes within the Third Liberalisation Package.
SuSTAINABLE (Smart distribUtion System operaTion for mAximazing the INtegration of renewaBLE generation) is a European project under the Seventh Framework Programme for Research and Technological Development with contract No: 308755, which the main concept involves an active management of distributed flexible resources by DSOs.
Salzburg is one of the pioneers in Europe in developing smart energy networks. This is why it was chosen by the Austrian Climate and Energy Fund to be the first Smart Grids Model Region in Austria. Smart Grids Model Region Salzburg is supported by an interdisciplinary team from the energy sector (Salzburg AG, Salzburg Netz GmbH), a property developer (Salzburg Wohnbau), a technology vendor (Siemens), consulting services (Fichtner) and renowned research institutions (Austrian Institute of Technology, Vienna University of Technology, CURE). The goal is to create a holistic smart grid system called Smart Infrastructure Salzburg.
COTEVOS project (Concepts, capacities and Methods for Testing EV Systems and their Interoperability within the Smart Grids) aims to establish the optimal structure and capacities to test the conformance, interoperability and performance of the systems to be included in the Electric Vehicles (EV) smart charging infrastructure.
SiNGULAR investigates the effects of large-scale integration of renewables and demand-side management on the planning and operation of insular electricity grids, proposing efficient measures, solutions and tools towards the development of a sustainable and smart grid.
The significant rise in distributed renewable energy sources has placed an enormous burden on the secure operation of the electrical grid, impacting both the transmission system operators (TSOs) and distribution system operators (DSOs). INCREASE wants to confront this challenge by developing novel control strategies and testing them in the field.
If the political goal of achieving a truly integrated Internal Energy Market goes beyond the energy-only market model, the roll-out of GSS market models throughout the EU must be considered. Therefore, the recommendations of the REserviceS project need to be taken into account, in particular in the revision of the EU-wide target model (TM) and specifically in the relevant network codes as well as in national grid connection requirements.
Within the scope of Smart Grids, stakeholders coming from different areas of expertise need to co-operate in order to design solutions that optimise electricity network management. Particularly relevant in this context is the information exchange between DSOs and vendors when procuring systems.
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.
In a field test, various energy feedback methods produced average electricity savings of 6.7 %, which because of the level of variance is of uncertain statistical significance and cannot be directly attributed to a particular feedback method. On the whole, feedback on electricity consumption is a valuable source of information for residential customers despite them losing interest. Generating an added value by integrating other services would offer a potential improvement. The same can be said for recommendations for shifting time of consumption in order to decrease electricity costs (a further value added feature). A decentralized solution for real-time feedback is recommended due to its lower costs. Data would be transferred from the smart meter to a gateway or a local computer and then visualized.
In contrast to a conscious change in behavior among residential customers, systems that condition buildings can be automated and therefore manage loads without being noticed by the user. This approach particularly uses thermal inertia combined with thermoelectric coupling in buildings, and takes into account existing technologies but also examines and develops new solutions. The former comprises systems that can be managed using ripple controls. Its load shifting potential has been shown to be approximately 10% of peak load in a select test area with a high penetration of electric space heaters. Due to its limited applicability and its neglect of processes within buildings, it can be seen as a transitional technology.
The second, more forward-looking approach is based on expanding building automation systems, for example, by incorporating the current condition of the network into the optimization process. A newly developed Building Energy Agent bundles all the shiftable loads in the building, in particular those of heating and cooling units, and communicates with the electricity system. If buildings are well insulated, electricity use from the heating system can be shifted by up to twelve hours without resulting in a loss of comfort.
