IEC/SC 8B - Decentralized electrical energy systems

To develop IEC publications enabling the development of secure, reliable and cost-effective systems with decentralized management for electrical energy supply, which are alternative, complement or precursor to traditional large interconnected and highly centralized systems. This includes but is not limited to AC, DC, AC/DC hybrid decentralized electrical energy system, such as distributed generation, distributed energy storage, virtual power plants and electrical energy systems having interaction with multiple types of distributed energy resources. A popular concept is currently the “microgrid” defined as a group of interconnected loads and distributed energy resources with defined electrical boundaries that acts as a single controllable entity and is able to operate in both grid-connected and island mode. Decentralized electrical energy systems have applications for developing countries (focussing on access to electricity) as well as for developed countries (focusing on high reliability, black-out recovery and services). Interactions within decentralized multi energy systems should also be considered. SC 8B coordinates with TC 8, SC 8A and SC 8C for topics such as renewable energy connection and management in micro grids or VPPs and microgrids/DEES (decentralized electrical energy system) interconnection with large interconnected networks. Standardization activities in SC 8B will proceed with cooperation with concerned TCs, SCs and SyCs, including but not limited to IEC SyC Smart Energy, SyC LVDC, TC 2, TC 22, TC 57, TC 64, TC 82, TC 88, TC 95, TC 99, TC 114 and TC 120. Also, SC 8B will cooperate with organizations such as CIRED, CIGRE SC C6 and others.
