摘要
随着二级电压控制目标的增多,以往加权组合的多目标处理方式在应对不同量纲和确定具体权系数方面日益困难。文中将多目标规划领域中应用较广且不受目标量纲和个数限制的线性目标规划引入二级电压控制领域,提出基于线性目标规划的二级电压多目标控制方法。该方法首先利用灵敏度分析将二级电压多目标控制问题描述为线性目标规划模型,然后根据运行状态通过规则对各目标优先级进行排序,按所得优化结果实施多目标控制。仿真结果表明,该方法能够根据优先级顺序兼顾各目标优化,获得较好的多目标控制效果。为更好地满足工程实际要求,文中还就该方法在适应工程应用方面做了进一步探讨。
With the growing number of secondary voltage control goals, the conventional weighted multi-objective optimization method is facing increasing difficulties in dealing with different dimensions and deterministic weight coefficients. The linear goal programming method is introduced into secondary voltage control domain, which is widely used in multi-objective programming methods and has no limitation of goal dimension and quantity. A new secondary voltage multi-objective control method based on linear goal programming is proposed. At first, the secondary voltage multi-objective control problem is represented as linear goal programming through sensitivity analysis, then the priority of each objective is ranked by rules and operating conditions, at last the optimal solution is used for secondary voltage multi-objective control. The simulation results show that each goal optimization is achieved according to the priority order, and the multi-objective control effect is satisfied. To meet the requirement of practical engineering applications further, an improved linear goal programming model of secondary voltage multi-objective control is discussed.
