Storage systems for microgrids
Change in the output of renewable energy considerably influences the quality of electric power in independent microgrids designed to realise local supply and consumption of energy. Accordingly, operating methods and costs were analysed for a microgrid incorporating two types of energy storage equipment: a sodium-sulphur (NaS) battery, and a hydrogen medium incorporating the OCHM. The installed capacity and cost were calculated, assuming an independent microgrid in Kitami City, a cold region in Japan. The OCHM-A system was designed to simulate energy storage similar to that of a battery, whereas OCHM-B was simulated to substitute power transmission or transportation of the OCHM.
