between LV customers and the network Giuseppe Mauri*, Roberto Meda* , Diana Moneta*, Paolo Gramatica* CIRED 2007-19th International Conference and Exhibition on ELECTRICITY DISTRIBUTION Vienna, 21-24 Maggio 2007 * CESI RICERCA In recent years European power sector has been undergoing considerable changes: from July 2007 all customers will be able to choose their own energy retailers. This will involve new roles both customers who will change from passive consumers to active participants and for energy distributors and retailers which will aim to attract customers providing new services. To get the most advantage from this opportunity there is the need of a technology platforms which can be interoperable with home and building automation systems and that will provide several functionalities: communication with energy distributors, retailers, interaction with consumers, management of loads, heating systems, energy storages and home micro-generation. In this way a global efficiency could be achieved. Households may become active "nodes" of the electric network which may receive and provide services both for the network (e.g. power modulation) and for the market (e.g. contribute to reduce price volatility). This paper illustrates an ICT architecture for delivering market and network signals to final users and specifies high level requirements for realization of applications and tools to be used by distribution utilities, traders and retailers to support the Integration of Demand-SideInitiatives (DSI) [1].
