摘要
给出了考虑负荷、供电电压水平约束和目标函数最小费用的不精细性的城市电网中压配电变压器位置、容量和供电范围的模糊优化规划模型及算法。在电压水平“硬”和“软”两种约束条件下 ,对确定性模型和模糊优化模型所得的优化方案进行了数值分析和比较。结果表明 ,模糊优化规划模型与确定性优化模型相比 ,其规划方案能够在成本大体不变的情况下 ,满足更多的可能性负荷的需求 。
In this paper,a novel fuzzy optimization model and algorithm to optimize the locations,sizes and service areas of MV/LV distribution transformers in urban distribution network planning which can consider the imprecision and possibility of spatial load,the voltage level constraints and the cost of objective function is presented. Numerical analysis and comparisons are accomplished for the schemes obtained from the deterministic model and the fuzzy model under the “hard”constraints and the “soft”constraints of voltage level. The results indicate that the scheme obtained from the fuzzy model can meet more load demand than that obtained from the deterministic model with a slight declination in the cost of objective function,and has a strong suitability for the uncertain environment.
