【摘要】 针对配电网因分布式电源接入带来的网损增加、电压质量水平下降的问题,提出了一种计及分布式电源无功调节能力、负荷时序变化的配电网多时段无功优化模型,并利用基于优秀粒子领导的改进差分算法进行优化求解。在Matlab中改进含分布式电源接入的IEEE33节点配电网算例计算验证表明,改进的差分算法可以有效降低配电网线路损耗,改善配电网的电压质量水平。更多还原

【Abstract】 This paper proposes a multi-period reactive power optimization model for network losses and voltage quality problems in distribution network with distributed generation(DG),which consider the DG reactive power regulation capability and load temporal characteristics.In addition,there is an improved differential algorithm as the optimal solution for the Optimization model.Based on the Matlab,it is demonstrated in the improved testing example of IEEE33 distribution network with DGs that improved differential algorithm can effectively reduce the line loss and improve the voltage quality level of the distribution network.更多还原
