错峰控制中兼顾双目标的断电模型分析

Novel Model of Power Terminate Plan Considering Two Object in Peak Load Shifting Control

提出了一种同时考虑居民不满意度和断电经济损失的错峰控制短期断电计划的多目标新模型。首先构造了居民的不满意度函数,其次,对两个单目标确定性模型求解得到目标函数值;最后,对目标值进行一定程度的伸缩,采用非线性规划方法求解,得到新的工业区以及居民区断电情况。仿真结果表明,提出的新策略在各自单目标优化值轻微伸缩的情况下使双目标综合考虑效果更好,该策略对可持续发展战略和错峰控制限电分配中多因素公平性有重要现实意义。

A novel multi-objective optimal short-term power terminates planning in a power system was proposed. Both dissatisfaction degree of dwellers and economic loss were considered in this model. At first, the dissatisfaction degree function of dwellers was constructed; secondly, each single-objective deterministic model was solved so that its objective value was obtained along with the results of unit commitment and power dispatch; finally, the multi-objective programming problem was reformulated into nonlinear Single objective programming problem so as to get the power limiting distribution of each zone. The numerical results demonstrate that the scheme obtained from the multi-objective model can meet functions better than that obtained from the single-objective deterministic model with slight variation in the every single-objective. This method of decision making is significant for sustainable development strategy and the multi-factor justice of power limiting distribution for peak load shifting control planning.
