摘要
为提高微电网运行经济性,建立了以微电网综合运行成本最小为目标函数的微电网优化调度模型。利用高斯变异和柯西变异对帝国竞争算法进行改进,采用高斯-柯西帝国竞争算法对微电网优化调度模型进行求解,并与其他优化算法对比分析。结果表明,高斯-柯西帝国竞争算法求解的微电网综合运行成本为4485.62元,低于其他优化算法;调度方案能够优化微电网系统内各分布式电源出力,合理与上级配电网交换电能,使微电网综合运行成本最小。验证了模型的正确性及求解方法的优越性。
In order to improve the operation economy of microgrid,an optimal dispatching model of microgrid was established with the objective function of minimizing the comprehensive operation cost of microgrid.Gaussian mutation and Cauchy mutation were used to improve the imperial competition algorithm,and Gaussian-Cauchy imperial competition algorithm was used to solve the microgrid optimal scheduling model,and the algorithm was compared with other optimization algorithms.The results show that the integrated operation cost of the microgrid solved by the Gauss-Cauchy empire competition algorithm is 4485.62 yuan,which is lower than that by other optimization algorithms.The dispatching scheme can optimize the output of each distributed generation in the microgrid system,reasonably exchange energy with the superior distribution network,and minimize the integrated operation cost of the microgrid.It verifies the correctness of the model and the superiority of the solution method.
