考虑DG和EV接入的分布式智能配电网联合规划
Joint Planning of Smart Distribution Grid Considering Distributed Generation and Electric Vehicle Charging Station
摘要
Abstract
When planning a smart distribution grid,it is necessary to consider the interests of various distributed generation(DG)operators,charging station operators and power supply enterprises.It makes the planning models diverse and complex.Therefore,the bi-level joint planning model has been proposed.On the basis of considering constraints such as power flow,node voltage and generator output,the lower-level planning of the distribution grid takes into account the initial investment cost,electricity sales revenue,generation subsidies,and grid costs for power distribution,and takes the maximum revenue of DG operators/charging station operators as the objective function,to determine the access location and capacity of DGs and charging stations.The upper-level planning takes into account the power purchase cost,network loss,and failure cost of the distribution network,with the goal of maximizing the profits of the power supply enterprise,to determine the investment projects of the distribution network.The solution of the bi-level planning model adopts the improved genetic algorithm,to perform implicit encoding for the access location and capacity of DG and electric vehicle charging station and the switch combination of distribution network projects,and the dynamic planning problem will be transformed into a nonlinear integer optimization mathematical problem.The practicability and effectiveness of this method are verified by an example of a regional distribution grid in a central city.关键词
