@@@@Abstact: For optimization of the voltage of the distribution network with distributed generation, an improved simulated annealing genetic algorithm is proposed in this paper. The improvements are done in initial population generation, fitness calculation, mutation operation, etc as well as adopting the self-adaptive weight sum in multi-objects optimization. The results of calculation case show that the improved algorithm is able to obtain a global optimum solution, and enhance the convergence speed and stability. By using the improved algorithm and through comprehensive voltage regulation with adjustable tap transformer and SVC, it is possible to improve the voltage quality of distribution network, and reduce its loss.
