摘　　要：高比例可再生能源接入电网是新型电力系统的重要特征。为在新型电力系统中促进可再生能源消纳,提升配电网的灵活稳定运行,提出一种配电网双层规划模型:规划层以配电网运营商年化成本最小为目标函数,计及碳排放指标,确定规划方案;运行层以灵活性运行成本最小为目标函数,确定各节点可中断、可转移电量。采用模拟退火粒子群算法求解,以提高算法全局搜索能力。最后,通过IEEE33节点配电系统进行算例分析,结果表明在规划阶段考虑灵活性需求能提高系统灵活性,减少配电网运营商的投资成本,验证了规划方法的有效性。Grid-connection of high proportion renewable energy is an important feature of new-type power grid.To promote the accommodation of renewable energy in new-type power grid and to improve flexible and stable operation of distribution networks,a bi-level planning model for distribution network was proposed.In the planning level of the proposed model the minimized annualized cost of distribution network operator was taken as the objective function and taking carbon emission target into account the planning scheme was determined.In the operation level the minimized flexible operation cost was taken as the objective function to determine the interruptible and transferable electric quantity in each node.The proposed model wad solved by simulated annealing particle swarm optimization,to improve the global search ability of the algorithm.Finally,by means of computing example based on EEE 33-bus distribution network system the proposed model was verified.Simulation results show that considering flexible demand in the phase of planning the system flexibility can be improved and distribution network operator’s cost of investment can be reduced,thus,the effectiveness of the proposed method is verified.
