Optimization Scheduling with Multiple Time Scale for Active Distribution Network Considering Electricity Price Elasticity
摘要
Abstract
The access of electric vehicles,renewable energy and energy storage to distribution network poses new challenges to the operation of distribution network.Without the proper scheduling method and model,the economy and reliability of distribution network will be affected.Worse,the enthusiasm of electric vehicle owners to participate in the dispatching will reduce.Accordingly,a optimal scheduling method with multiple time scale is proposed for the active distribution network. First,an electric vehicle charging model based on elastic electricity price is constructed.Meanwhile,a day-ahead economic scheduling model of active distribution network is established.Secondly,in the real-time scheduling stage,the bias of renewable energy forecast is reduced by using the energy storage and electric vehicles.Based on the renewable energy forecast results and the study of the influence mechanism of elastic electricity price on electric vehicle charging,the optimal operation of electric vehicle,storage and flexible load is obtained.Simulation results show that the proposed method can reduce the cost of purchasing electricity in the distribution network and electric vehicles charging,weaken the influence of the bias of renewable energy forecast on the distribution network and optimize the characteristics of load.关键词
