基于改进萤火虫算法的农村配电网分布式电源优化配置

Distribution Power Optimization Configuration of Rural Distribution Grid Based on Improved Firefly Algorithm

为了借助分布式电源就近供电的优势,进一步改善农村配电网负荷的供电质量,本文针对分布式电源在农村配电网中的优化配置问题,建立了综合考虑分布式电源建设运行总成本与农网网络损耗的多目标优化配置模型,并提出一种基于自适应步长策略的萤火虫优化算法用于农村配电网分布式电源的优化配置,并应用交互式模糊决策技术从前期优化配置pareto解集中选取最优配置方案。通过IEEE-33节点的配电网算例的仿真与分析,验证了模型的可行性与方法的有效性。

For further improvement of power supply quality of load at rural distribution grid with help of the advantage of near power supply of distributed generators and as for the issue of optimization config- uration of distributed generators in rural distribution grid,the multiple objective optimization configu- ration mode with comprehensive consideration of the construction and operation cost of the distribution power and loss of rural grid is established in this paper. A kind of the firefly optimization algorithm bas- ed on adaptive step strategy for the optimization configuration of distributed generators of rural distri- bution grid is proposed and the best configuration proposal is selected from earlier optimization config- uration pareto disaggregation by the use of fuzzy decision technology.The feasibility of the model and the effectiveness of the method are verified through simulation and analysis of distribution grid example of IEEE 33 node.
