考虑灵活性资源的微电网双层优化策略
Two-layer Optimal Strategy for Microgrid Considering Flexible Resources
摘要
Abstract
To improve the capability of microgrid in coping with new energy output and load uncertainty,an optimal control strategy for microgrid considering flexible resources is proposed.According to the source-storage-load characteristics of various flexible resources,a two-layer optimal scheduling model for microgrid is established.In the user layer,user-side flexibility resources are introduced,with an optimization goal of minimizing the difference between user costs and net load and decision variables of electric vehicles and output power of translatable loads.In the source-storage layer model,flexible resources are added to the energy storage and power generation sides,with an optimization goal of minimizing the microgrid operators'cost and load loss rate and decision variables of gas turbines,main network tie-line and output power of energy storage unit.A case study based on scenario-reduced seasonal typical daily data is simulated,and the improved MOEA/D(multi-objective evolutionary algorithm based on decomposition)algorithm is used to solve the two-layer optimal scheduling model.Results show that the average annual user cost is reduced by 6.85%,the average annual total cost of operators is reduced by 14.68%,and the average annual load loss rate is reduced by 6.65%.The results verified the correctness and effectiveness of the proposed method.关键词
