摘　　要：为了使当前电网储能系统运行更加稳定,电量损耗更少,研究在列约束生成算法的基础上对其进行改进,通过加入粒子群算法对系统的位置等参数进行计算,再使用列约束生成算法进行分析。研究结果表明,不同场景的全天电压分布情况基本在电压1.0 p.u.之间变化,场景1的最低电压值分别为,0.351 p.u.、0.421 p.u.和0.432 p.u.,场景2的最低电压值分别为0.543 p.u.、0.423 p.u.和0.321 p.u.。不同场景规划后的充放电过程更加充分,场景1中的配电网储能系统运行较为平稳,电量的释放和充盈都能够满足配电网的运行。场景2中配电网的储能系统基本处于充电过程,这个系统都能够完成当前时刻的电量储能过程。由此可见,使用改进列约束生成算法能够提升储能系统的运行状态,这为该领域的研究提供了新思路。This study was conducted in order to make the current grid energy storage system operate more stably with less power loss.The column constraint generation algorithm is improved on the basis of the column constraint generation algorithm by adding particle swarm algorithm to calculate the position and other parameters of the system,and then analyzed using the column constraint generation algorithm.The results of the study show that the all-day voltage distribution of different scenarios basically varies between voltages 1.0p.u.The lowest voltage values for scenario 1 are,respectively,0.351 p.u.,0.421 p.u.and 0.432 p.u.,and for scenario 2,the lowest voltage values are,respectively,0.543 p.u.,0.423 p.u.and 0.321 p.u..The charging and discharging process after planning for different scenarios is more adequate,and the energy storage system of the distribution grid in Scenario 1 operates more smoothly,and the release and filling of power can meet the operation of the distribution grid.The energy storage system of the distribution grid in Scenario 2 is basically in the charging process,and this system are able to complete the power storage process at the current moment.It can be seen that the use of the improved column constraint generation algorithm can enhance the operation of the energy storage system,which provides a new idea for the research in this field.
