摘要

研究了含风力发电的无功优化模型，介绍了包含分布式发电的配电网无功优化。当大量风力发电注入电力系统时，风力发电机随机输出功率引起配电网潮流大小、方向频繁变化，干扰了系统原有电压调节装置正常运行。为克服电压波动，保证系统电能质量，文中引入静止无功补偿器（SVC）作为配电网补偿设备，并考虑配电网中可控制无功输出的柴油发电机的无功贡献，以有功能耗费用、SVC安装费用、柴油发电机无功生产费用为目标函数，建立了含分布式发电的配电网无功优化模型。针对由蒙特卡罗仿真得到的不同风力发电状态，在实际算例中应用遗传算法确定各状态下SVC最优安装位置、输出以及可控制无功输出的分布式电源的最优输出结果。

Abstract

A method for optimal reactive power planning of radial distribution systems with distributed generation is proposed. The wind power generation units installed in distribution systems may cause reverse power flow and voltage variations due to the randomlike output of wind power generation units. To conquer that disturbance

an optimal reactive power planning model is proposed to combine the reactive power support from SVC and distributed diesel units

and the optimal object is consist of power loss cost

SVC installation cost

reactive power production cost of diesel units. With the genetic algorithm as the optimization method and using Monte-Carlo simulation

the location and the output of SVC and distributed diesel units are determined. The proposed model is applied to a sample system.
