Abstract:Regarding optimal design of wind/photovoltaic/energy storage hybrid power systems, on the condition of reliability, considering the output characteristics of wind turbines, PV phalanx, pumped storage power plants, batteries and other components, as well as the operation mode of energy trading system, an appropriate optimization model is established, the goal of which is to minimize the total cost. In addition, the impact of certain factors on the optimal allocations of wind/photovoltaic/energy storage hybrid power systems is analyzed. And the factors are reliability constraints, tariff, energy trading system capacity and optimizing way. This study can provide reference for optimal design and operation of the hybrid system.
