摘要
由于电力系统本身的复杂性,电力潮流优化具有规模大,约束条件多和非线性的特点。通过对最优潮流的求解,最终达到优化已有资源、降低发电厂耗量成本、减少电网线路损耗、提高电力系统输电能力等目标,其相比较传统的潮流计算具有良好的经济性。因此,最优潮流是电力系统中及受关注的课题,目前也有很多针对其做出的研究。本文综述了电力系统最优计算的数学模型和优化方法的研究现状。介绍了内点法的理论基石和基本原理,建立了最优潮流的数学模型,并对该模型采用内点法进行求解,最后通过实际算例加以验证。
Optimal Power Flow is a large -scale, multi-constrained, nonlinear optimization problem. By solving the OPF problem can achieve targets of optimize existing resources, reduce the cost of power generation and reduce transmission losses, improve system transmission capacity and so on. It has the technical and economic significance of the traditional power flow calculation can not be realized. Optimal Power Flow has been a challenging issue ; the majority of scholars have done a lot of it. The development of optimal power flow and optimal power flow model and optimization method of re- search is reviewed in this paper. And the problems of the optimal were pointed out. The mathematical model of OPF, the theoretical foundation and basic principles of the Interior-point method in detail are discussed. The mathematical model of static voltage stability constrained optimal power flow is established with using interior-point method to solve the model.
