The TILOS project is testing the integration of an innovative local-scale, molten-salt battery (NaNiCl2) energy-storage system in the real grid environment on the island of Tilos (Greece).
It is planned to test smart grid control system and provision of multiple services, ranging from microgrid energy management, maximisation of RES penetration and grid stability, to export of guaranteed energy amounts and provision of ancillary services to the main grid. The battery system is used to support both stand-alone and grid-connected operations, while ensuring its interoperability with the rest of microgrid components and demand side management.
New case studies examining different battery technologies and microgrid configurations (stand-alone, grid connected and power market-dependent) are being prepared using advanced microgrid simulating tool (the Extended Microgrid Simulator).
Social issues are also well considered through public engagement, and by developing novel business models and policy instruments.
The prototype molten-salt, battery-storage system will improve micro-grid energy management and grid stability, increase renewable energy use and provide services to the main grid. If successful, this energy storage technology could be widely replicated on islands to complement and encourage the use of variable renewable energy sources.
