摘要： 摘要：针对电力系统经济调度问题的多目标性及在实际问题中每个目标函数重要性存在的差异，提出了一种求解电力系统经济调度问题的模糊线性加权法。即对每个目标函数的隶属函数采取线性加权的方法求解电力系统的经济调度问题，利用lingo进行算例仿真，结果表明该算法的有效性；同时，将模糊线性加权法和极大极小法的解进行对比，结果表明模糊线性加权法更符合实际。

Abstract: Abstract:The power system economic dispatch is multiobjective, and in practice, the importance of each objective function is different. Aiming at above situation, a fuzzy linear weighting method for solving economic dispatch problem of power system was proposed. In this method, the linear weighting method is used in the membership functions of each objective function to solve the economic dispatch problems of power system, and the Lingo software is used in example simulation. The solutions of the fuzzy linear weighting method and the minimax method were compared, and the comparison results show that the fuzzy linear weighting method is more suitable for practical problems.
