The study of mountain area distributed generation optimal access capacity and position

分布式电源接入位置与容量的不同会对电网产生不同影响,如何确定最优的接入位置及容量是保证分布式电源接入系统经济性运行的关键因素。以系统网损最小为目标,考虑到分布式电源接入对系统潮流分布的影响,建立了福建省山区配电网网损目标函数模型,模型中以系统功率及电压为约束条件,提出利用萤火虫优化算法对分布式电源最优接入位置及容量进行寻优。该算法操作简单,具有很好的全局寻优能力。通过算例分析,验证了该算法在求解中的有效性。

The grid can be influenced by different access capacity and position of distributed generation, how to determine the optimal access capacity and position is the key to keeping the grid economic running. The model of Fujian mountain network loss objective function is established in this paper, considering the power flow with the access of distributed generation, the power and voltage are the constraint conditions. Then, the firefly algorithm is proposed to getting the optimal access capacity and position of the distributed generation, the algorithm is simple and has better ability for global optimization. The feasibility of firefly algorithm is validated through the ease analysis.
