Study on Optimal Operation of Wind Power-Photovoltaic-Pumped Storage-Diesel Power Generation Microgrid Connected Grid
In order to suppress the output fluctuation of wind power and photovoltaic power and improve the consumption ratio,a distributed grid connected microgrid model composed of wind power,photovoltaic,diesel power generation and pumped storage power stations is established.Wind power photovoltaic is the main output object of microgrid,diesel power generation is the emergency standby power supply measure,and pumped storage power station is the energy storage and transfer equipment to complete the storage and conversion of renewable energy.Analyze the output characteristics and user load of microgrid components,take the lowest operation cost and system power outsourcing rate as the optimization objective,establish the optimal operation mathematical model,and combined with the actual example,use the improved multi-objective clonal selection algorithm to solve,so as to obtain the Pareto solution of optimal operation,it can provide the output of each power generation unit in each optimization period under the optimization objectives of operation cost and power outsourcing proportion,which has certain theoretical research and engineering practical significance.
