1. PROJECTVirtual Power SystemsSession: « Developing an integrated local and regional approach to energy savings, smart grids and other innovative solutions”CoR seminar. Cagliari October 22nd, 2010Roger Léron DR R.Vezin DR

2. Context for Virtual Power Systems • Deployment of decentralised renewable energy sources • Intermittency aspects and network investment requirements • Market deregulation, competitive environment, presence of new players (energy providers) • Requirements for data exchange • Electricity European Directive (13 July 2009) • Implementation of smart metering systems • Communication technologies available and mature

3. VPS are about managing Production and Consumption • VPS (Virtual Power System) • matching generation and consumption (including storage) • optimizing usage of existing grid • new business models (tariffs, services) CONSUMPTION PRODUCTION • VPP (Virtual Power Plant) • multiple power generators (different type) • controlling effectiveness and efficiency • protection of grid (no overloads, no peaks) • VLP (Virtual Load Plant) • multiple power consumers (private, biz) • demand side management to control load • controlling and optimizing appliances

4. european partnership 5 Countries, 12 Partners 3 years project Project financed by the Alpine Space Interreg programme and Rhône-Alpes Region Total Budget EU : 2M€

5. objectives in Rhône-Alpes Key Objective • Facilitate the development of electrical RES in the region (French objective : 23% in 2020) • Increase the rational use of energy in households, public buildings and SME Detailed Objectives • Study the aggregation of RES productions (group of producers) for a better economic value and a lower impact on the network • Find the best place for future renewable energy sources on the local network in rural territories • Experiment the use of “loads management” to solve network constraints

6. partnership in Rhône-Alpes • Partnership between the regional energy agency, • a company controlled by municipalities (régie) • a federation of municipalities for energy management (syndicat) • And a public laboratory from Grenoble university • work on the optimisation of the networks through : • Network modelling • Simulation of load management • Simulation of RES integration

7. Work done with Work with the company controlled by municipalities (Régie d’Allevard) – local producer, distributor, and provider of electricity Study area : 5 communities, 5000 customers, 42 million kWh / an • Issues : • Aggregation of productions for a better economic value and services to the network • Simulation of loads management on the network for better prices for the company and the customers

8. Work done with Work with Federation of municipalities for energy management (Syndicat) – authority in charge of public service Study area : 3 Cantons, 55 communities Objective : Solve a network constraint and avoid reinforcement on 63kV line Issues : • Load management with energy boxes (modelling and experimentation) • Simulation of RES integration on the network

9. VPS – Perspectives • VPS and smart grids technologies are a key investment for an effective deployment of RES • Technologies can support a large variety of applications allowing for: • network simulation and optimisation, • demand side management programs, • new customer services (information, new tariff structures, load management,..) • Economic and social impact analysis are required to support a successful deployment of these systems • Public service of distribution and transport has to guarantee the reliability, efficiency and general interest of new services developed
