摘要:
经济负荷分配是电力系统中重要的优化问题。该问题有若干约束，以往文献常采用罚函数法来处理约束。然而，罚函数法难以设置罚系数。可行性规则和 约束法是两种高效且常用的约束处理技术，但却难以直接应用于经济负荷分配问题。结合问题的特点，提出了一种将负荷平衡约束转化为边界不等式约束的方法。然后采用基本差分进化算法结合可行性规则和 约束法对其进行求解。采用两个经典的经济负荷分配问题对算法进行了测试。结果表明，与以往文献中的其他算法相比，该方法能求得更优的解。
Abstract:
Economic load dispatch is an important problem in power system. Some constraints exist in this problem. In literatures, penalty function methods were usually used. However, it is difficult to set proper penalty coefficients. Feasibility rules and constraint method are two popular constraint handling techniques. However, they are not efficient for economic load dispatch problem. A constraint handling method which transforms the load balance constraint to two boundary constraints is proposed in this paper. Combined with feasibility rules and constraint method, a basic differential evolution is used to solve this problem. Two classic instances are tested. The results show the proposed algorithm obtains better solutions than other compared algorithms in literatures.
