Abstract:
This paper proposed an improved differential evolution algorithm for solving economic load dispatch (ELD)
problems of power systems. In the proposed algorithm, the double mutation operators are employed. One is used to maintain
the diversity of the population; and the other is to accelerate the convergence speed. Meanwhile, an adaptive updating
method of parameter and a chaotic local search is introduced to improve the performance of IDE. Finally, two types of ELD
problems were used to test the efficiency of the proposed algorithm. Experimental results show that the proposed algorithm
can effectively solve these problems.
