ICER: Power System Control Design, Forecasting and Optimization using distributed energy storage systems

The International Center for Energy Research (ICER) is a cooperation project between Technical University of Munich (TUM) and Nanyang Technological University (NTU) in Singapore. As one of the 10 research projects within ICER, the EES project „Design and control of distributed energy storage system for the ASEAN region“ will examine the benefits of battery storage systems in island grids with distributed energy producers and loads.

Stationary energy storage can be used to increase the utilization of renewable energy sources and to reduce the cost of diesel generators, which are conventionally deployed. However, there are so far neither standardized design rules yet nor sophisticated technical concepts for the optimal sizing and economically optimal operation of island power grids with distributed renewable producers, loads and energy storage.

For this purpose, in this ICER project in cooperation with the partners of the Energy Research Institute of NTU (ERI@N) a generic tool is to be designed, which is intended to show how renewable energy sources, energy storage and eventually electric vehicles can be integrated into an island electricity grid with an energy management system. This generic tool can then be used to plan the design of a stand-alone grid with a given topology and a defined mix of various energy producers. This allows the most efficient use of renewable producers in connection with the energy storage, in order that in each case the appropriate amount of energy is saved at the right time and the efficiency can be maximized for all components and users of the system. This approach requires the techno-economic modeling of the complex hierarchy of an energy management system and all technical units such as intermittent generation, the power grid and the energy storage in the interconnected operation.
