This paper addresses the issue of network partition used in power system analysis for ancillary services in distribution networks with distributed generation. Simplification and reduction of the computational effort in network calculation for centralized control can be achieved, through a definition of suitable partitioned clusters. The zoning problem is explored using a clustering process based on...
This paper presents the DER aggregation solution that will be deployed in the frame of the Reflexe pilot project. This project brings together a consortium of industrial partners and research laboratories with the objective of examining all aspects of the commercial and industrial flexibility aggregation activity in order to provide energy and ancillary services to the grid through the market. The...
The article presents the Nice Grid demonstrator, its objectives as well as its technical and functional architecture. This Smart Grid pilot project is about demonstrating the management of distributed energy resources located in a solar district. Three innovative operation modes of the distribution grid will be tested in order to gain experience on improving network reliability through demand management,...
Meeting peak demand is a major concern for grid operators, sometimes amplified by the liberalization of the electricity industry. Peak resources operate during a short period, at a high operating cost, and face difficulties to recover their investments. Sending the proper market signals to trigger long term generation investments in these types of generating units is a critical issue. Different incentivizing...
During last years, the Italian Electricity Market has seen important changes, aimed at reducing the cost for consumers as well as at improving efficiency and transparency. In this context, the Ancillary Services and Balancing Market (MSD) is operated by the Italian Transmission System Operator, Terna, to procure resources to relieve grid congestion, to build operational reserve and to balance the...
The presence of distributed generation poses new challenges in the management and operation of electrical grids. Distributed generation (wind, combined heat and power, etc.) already accounts for 20% or more of total generation in some electric utilities and this figure is constantly increasing worldwide. TSOs, DSOs and energy markets need to have some visibility on a large number of small power injections...
