摘　　要：针对配电网无功补偿特点,提出一种补偿效益极限最优两步搜索算法,可快速确定网络中待补偿点的位置及个数,有效压缩无效解空间。结合自适应遗传算法,引入了模拟退火机制和罚因子自适应调整策略,可促使算法趋向全局收敛。文中以配电网年电能损失、无功补偿设备投资和补偿点固定安装费用之和最小为目标,建立了无功优化的数学模型,并用IEEE 33节点算例证明了该方法的优越性与可行性。In the light of the characteristics of reactive power compensation in distribution networks, an optimization algorithm is proposed, by wbich the best location and capacity can be determined to compress the space of invalid solutions. In the improved genetic algorithm, a simulated annealing and the adaptive adjustment mechanism of penalty factors are used. Taking minimum sum of annual loss of electrical engineering,investment of reactive power compensation devices and fixed installation cost at the compensating nodes as objective function,the mathematical model of reactive power optimization is established.The feasibility and superiority of the method are proved by the results of IEEE33 node network.
