摘要
提出了一个综合多个目标的日有功负荷分配集中优化模型。用模糊集理论将多目标函数模糊化 ,然后用最大最小法将多目标问题转化为单目标非线性规划问题 ,从而用原—对偶路径内点算法求解。算例仿真结果表明 ,该模型与各单目标的确定性优化模型相比 ,在各单目标值轻微伸缩的情况下 。
A new multi- objective fuzzy optim ization m odel for daily active power dispatch is proposed.By using fuzzy set theory the multi- objective function is fuzzified and is reformulated into a standard single- objective non- linear programm ing problem by means of max- m in operator.Then it can be solved by the primal- dual interior point algorithm .The num erical results indicate that the scheme obtained from the multi- objective fuzzy m odel can meet functions better than that obtained from the single- objective deterministic model with slight variation in the every single- objective.
