【摘要】 电力系统厂网分开后,统一经营调度模式下的无功优化目标已不再适用。据此,本论文将研究电力市场下的无功优化数学模型。无功优化本身是一个复杂的非线性规划问题。本文针对该问题的特点,在深入研究了遗传算法的组成结构和优化原理的基础上,提出并实现了用改进免疫遗传算法对该模型进行求解的方案,该算法结合生物学中的免疫原理,形成充分发挥两种寻优策略优点的混合优化策略。论文还着重讨论了算法中免疫疫苗的提取。形成了一个有效的无功优化疫苗集合。对IEEE 30节点系统进行试算,结果令人满意,验证了本文所提出的电力市场下的无功优化模型和算法是正确而有效的。

【Abstract】 After power system is unbundled, the management mode of reactive power is changed. Therefore, the model of reactive power optimization is studied in this paper.The mathematical model of reactive power optimization is a complex nonlinear planning problem. This paper solves the problem by using a modified immune genetic algorithm, which is a mixed optimal strategy. In this paper, a set of vaccine is formed based on reactive power optimization in electricity market The proposed algorithm is applied to the IEEE 30-bus system. The numerical results verify the correctness and validity of the proposed model and method. Peng Yonghua(Automation of Power System)Directed by prof. Zhang Lizi
