【 摘 要 】

Fluctuations of electricity prices in demand response schemes and intermittency of renewable energy supplies necessitate the adoption of energy storage in power systems. This paper considers the heterogeneous cloud energy storage (HCES) on cloud energy storage operator side. The goal of this approach is to lower the cost of energy storage by exploiting the different operating characteristics and economics of different battery energy storage technologies. The customers are screened from the type of storage facility that they have purchased and cloud energy storage (CES) operator can maximize the benefit if the complementarily of the storage technologies can be utilized. Distributed generation such as photo-voltaic (PV) generation has also been considered on both side consumer as well as CES operator side for supplying power to energy storage facilities to reduce the cost of charging power. Furthermore, the paper also presents an economic viability of heterogeneous storage system using investment analysis methods. Numerical simulations are carried out based on HCES technological characteristics such as self discharge, round trip charge-discharge cycle efficiency, depth of discharge (DOD) and cycles life time. There is significant changes in the economic performances using HCES when compared with single energy storage.
