为保证主动式配电网经济运行并改善负荷曲线,提出一种主动式配电网多目标优化调度方法.选取含分布式电源的主动配电网综合运行成本最低和负荷曲线方差最小为优化目标,以系统功率平衡、电源出力、爬坡率等为约束,构建含分布式电源的主动式配电网多目标优化模型.使用改进的非劣排序遗传算法(NSGA-Ⅱ)与博弈论相结合的求解方法计算最优解.算例仿真结果表明该方法具有可行性和有效性.

In order to ensure the economical operation of the active distribution network and improve the load curve, a multi-objective optimal dispatching method for active distribution network was proposed. The minimum comprehensive operation cost and minimum load curve variance of active distribution network with distributed generation were selected as the optimization objectives, and the system power balance, power output and slope climbing rate were taken as the constraints. The multi-objective optimization model of active distribution network with distributed generation was constructed. The optimal solution was calculated by using the improved non-inferior sorting genetic algorithm(NSGA-Ⅱ) combined with game theory. Numerical simulation results showed that the method was feasible and effective.
