In centralized energy storage systems, the DC side of multiple battery clusters adopts a parallel architecture. When one battery cluster is fully charged or discharged, the entire system stops charging and discharging. The overall life of the system depends on the battery with the shortest life.
Multi-energy storage system employing different types of ESS helps to meet the complementary coordination between different types of energy storage, which is important in improving system flexibility, reliability and economy . Because of these advantages, the researches on hybrid energy storages of electricity and heat in RIES gradually rose.
The integration of multi-energy storage systems utilizes the time-of-use tariff for price arbitrage and reduces the operating cost of RIES. Fig. 9 displays the wind power dispatch and wind curtailment under the original strategy S0 and the strategy S3 of multi-energy storage system.
