基于人工蜂群算法的微电网环保经济调度

为解决含多种分布式能源的微电网负荷优化分配问题,建立了以系统总成本最小为目标函数,以系统安全运行为约束条件的微电网环保经济调度模型。将人工蜂群算法应用到模型求解中,通过14节点系统验证该模型和方法的有效性。算例结果分析表明,通过合理安排微电网内部"可控"分布式电源(DG)的出力和分布式储能(DS)的充放电功率,实现了负荷转移,有效降低了微电网系统总成本。

Environmental and Economic Dispatch of Microgrid Based on Artiifcial Bee Colony Algorithm

In order to solve the optimal load distribution problem of microgrid with multiple distributed energy resource, this paper estab-lished the function taking the minimum total cost as its objective and the environmental economic dispatch model of microgrid with the system security operation as its constraints. Artiifcial bee colony algorithm was applied in the solution method for model and the validity of this method was veriifed by the 14-node system. The result analysis of algorithm case shows that the reasonable arrangement capacity of microgrid interior controllable distributed generation and the charging and discharging power of distributed energy storage realizes the load transfer and reduces the total cost of microgrid system.
