含分布式发电系统的配电网无功优化研究

摘要

This paper introduces the cost of power loss,capacitors and distributed generation, fully considering the objective function of penalty functions based on voltage quality and reactive power compensation capacity, thereby constructs a reactive power optimization model including distributed generation system. PSO algorithm is used to a changing update method. additionally variability factors are introduced in the latter period. The examples show that the proposed model and algorithm are feasible and strong convergence; additionally it has a certain reference value in distribution networks with distribute generation.%引入有功网损、电容器以及分布式发电的费用,并充分考虑了电压质量和无功补偿容量作为罚函数的综合目标函数,采用PSO算法时运用改变更新方式,并在后期引进变异因子,建立了含分布式发电系统的配电网无功优化模型.通过算例表明,验证了模型和算法是可行的,具有较强的收敛性,对分布式发电并入配电网的运行具有一定的参考价值.
