Abstract

Because the traditional power generation method has caused certain damage to the environment, the microgrid system composed of renewable energy has been widely developed and applied. This paper studies distributed power sources including photovoltaics, wind turbines, energy storage systems, gas turbines, and fuel cells. Under the conditions of microgrid islands and grid-connected operation, the fuel cost, operation and maintenance cost, and the electricity transaction cost between the microgrid and the distribution network, establish the optimal objective function for the operating cost of the microgrid. At the same time, due to the standard moth-flame optimization algorithm having low optimization accuracy and are easy to fall into local optimal solution, an improved moth-flame optimization algorithm based on Sine mapping and Gaussian mutation is proposed. This algorithm is used to obtain the output of each distributed power source and total operating cost in a dispatch period. Finally, an example is used to verify the effectiveness and economy of the proposed model and the improved algorithm.
基于正弦映射和高斯突变改进蛾焰优化算法的微电网优化调度
由于传统的发电方式对环境造成了一定的破坏,由可再生能源组成的微电网系统得到了广泛的开发和应用。本文研究了分布式电源,包括光伏、风力涡轮机、储能系统、燃气涡轮机和燃料电池。在微电网孤岛和并网运行的条件下,微电网与配电网之间的燃料成本、运维成本以及电力交易成本,建立了微电网运行成本的最优目标函数。同时,针对标准飞蛾火焰优化算法优化精度低、容易陷入局部最优解的问题,提出了一种基于正弦映射和高斯变异的改进飞蛾火焰算法。该算法用于获得一个调度周期内每个分布式电源的输出和总运行成本。最后,通过算例验证了该模型和改进算法的有效性和经济性。
