Optimal Design and Analysis of Wind/Photovoltaic/Energy Storage Hybrid Power Systems

Wind, photovoltaic(PV), energy storage resources are complementarity, thus it is more economical and reliable for wind/photovoltaic/energy storage hybrid power systems. As for optimal design of wind/photovoltaic/energy storage hybrid power systems, under the premise of the reliability, considering the generation characteristics of wind turbines, PV phalanx, pumped storage power plants, batteries and other components , as well as the operation mode of energy trading system, the appropriate optimization model is established, the goal of which is to minimize the total cost. In addition, the impact of five factors on the optimizing 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 the reference for optimal design and operation of the hybrid system.
