摘要: |
对智能电网下微电网系统的可再生能源电源扩展规划进行研究。将微电网看作一个复杂系统,综合考虑微电网的可靠性、微电网运行耗损费用与维护费用和扩展方案总费用3个方面,建立了微电网系统中风力-火电联合发电的扩建模型,并采用和声搜索算法对其进行优化求解。利用所提方法对一个具有5节点微电网系统在10 a内的电源规划扩展方案进行了模拟,并通过将所得结果与遗传算法结果进行对比,说明了该方法的可行性和有效性。 |

Abstract: |
The expansion planning of co-generation system in the microgrid of smart power grid is studied and an expansion planning model is built,which takes the microgrid as a complex system,considers comprehensively its reliability,operation & maintenance cost and total expansion cost,and applies the harmony search algorithm to obtain the optimal solution. A 10-year expansion scheme is planned for a 5-bus simulation microgrid and the simulative results are compared with those of genetic algorithm to show the applicability and effectiveness of the proposed method. |
