Robust Optimization Model of Island Energy System Based on Uncertainty of Wind and Photovoltaic

Multiple energy complementarity is an effective way to solve the problem of energy supply in the island and remote areas. According to the characteristics of load demand in the island energy supply system and considering the economic and environmental benefits of the island energy supply system, this paper puts forward a strategy to coordinate the operation capacity of wind power, photovoltaic, battery and diesel generator. On this basis, a robust optimization model of wind/light/Diesel/storage and an island type energy supply system is proposed. The uncertain set of wind power and photovoltaic unit output is also constructed. The improved PSO algorithm is used to solve the proposed model. The results of example verify the effectiveness of the proposed robust optimal allocation model can solve the capacity allocation of the island energy supply system, and provide a theoretical basis for the design of the island energy system.
