电力系统多目标优化运营研究

针对智能电网系统的安全与经济运行问题,建立了一个同时考虑经济、环境和安全指标的电网系统多目标优化模型,并运用理想点法对电网系统的多目标优化运营问题进行了相应的决策性分析,然后使用了一种新型的智能计算方法——标杆管理优化算法对该模型进行了求解计算.仿真实例表明,本文提出的决策分析和求解计算方法是切实可行的,具有一定的实用性和灵活性.此外,在计算过程中对一些相关的技术性问题,如对协调模型中的两类不同的控制变量、基因链的构造、约束条件的处理以及目标函数的选取等问题做了一些研究和探讨.

Studing on Multi-Objective Optimization in Power Grid System

For the safe and economical operation of the smart power grid system,a multiobjective optimization mode,containing the economic,environmental and safety index,was proposed in this paper.TOPSIS method was used in the decision-making analysis for the power system multi-objective optimization operation.A new type of intelligence computation method—Benchmark learning Algorithm got used for the optimization mode.The simulation experiment showed that the method of decision analysis and computation proposed here was practical and flexible.Furthermore,some related technical details,including two different types of control variables in the mode,gene chain,constraint condition and objective functions,was analyzed and discussed in the process of calculation.
