AISPSO算法在电网无功优化的应用
Journal of Shanghai University of Engineering Science(2019)
Abstract
针对粒子群算法搜索后期的局部收敛问题,提出加入邻域空间和择优替换粒子改进方法的自适应信息选择粒子群优化(AISPSO)算法.将AISPSO算法应用于电网无功优化,选取发电机节点电压、变压器、无功补偿容量为控制变量,代入粒子编码机制寻优,在连续5次迭代无法跳出时,加入邻域空间,替换粒子后再次搜索.通过AISPSO算法优化调度,搜索电网网损最优值,达到电网无功优化目标.根据研究数据对比,AISPSO算法寻优所得网损比基本粒子群算法降低了4.43个百分点.
