TILOS – Technology Innovation for the Local Scale Optimum Integration of Battery Energy Storage
The TILOS project aims to demonstrate the optimal integration of local scale energy storage in a fully operated, smart island microgrid that will also communicate with a main electricity grid. The main objective of the project is the development and operation of a prototype battery storage system, based on NaNiCl2 batteries, provided with an optimum, real-environment smart grid control system. The system will be coping with the challenge of supporting multiple tasks, ranging from microgrid energy management, maximization of RES penetration and grid stability, to export of guaranteed energy amounts and provision of ancillary services to the main grid. The battery system will support both stand-alone and grid-connected operation, while proving its interoperability with the rest of the microgrid components.
The contribution from ISEA involves extensive knowledge about operation and behavior of a large-scale battery energy storage system to provide a stable supply of electrical energy from fluctuating renewable sources. Battery aging and the related effects on system reliability and economics are key factors. To determine these effects and to enable further analysis of alternative systems with a similar scope, a simulation toolbox has been developed. This toolbox enables a simulation-based assessment of regionally and technologically variable use cases, providing a modular structure and various established types of storage to address different aspects of the challenges for future energy island systems.
