Based on the relevant characteristics of the hydro-photovoltaic hybrid energy system, the optimal economic operation of a clean energy power system by combining hybrid energy storage has been investigated where the system integrates with electrolyte-chemical energy storage and hydrogen energy storage technologies. With the target of the minimum net present value (NPV) cost of the energy storage system by utilizing the energy storage system capacity to maximum charge and discharge power. The economic benefits of different types of energy storage devices, according to the current standard price in Guizhou Province, China are discussed. Its economy performance are compared where the storage system are located by power generation side, power grid side and financial leasing mode. Under multiple application scenarios, revenue models under each application mode are built and investigated. The study outcomes provide valuable solutions for the practical application of energy storage technologies in photovoltaic power applications in this region.
