微电网多目标优化运行综述

Review of Multi-objective Optimization Operation of Micro-grid

微电网中的分布式电源随机性很大,易导致微电网调度计划出现偏差或运行经济性变差。因此,微电网运行亟待优化。首先对微电网的主要结构、运行模式以及运行特点进行分析,对于含有多个目标的微电网优化运行数学模型,分别从经济效益、环境效益、安全可靠效益与用户满意度4个方面分析微电网运行优化的目标,并对微电网的约束条件以及约束条件的处理进行梳理,进而对微电网多目标运行优化求解的常用智能算法进行归纳总结,为微电网运行优化提供科学可行的理论指导,具有一定现实意义。

The performance of distributed power in the micro-grid is hardly predictable,which easily leads to deviations in the micro-grid dispatch plan or worsening of the operation economy.Therefore,micro-grid operation needs to be optimized.In this article,the main structure,operating mode,and operating characteristics of the micro-grid are analyzed firstly.For the mathematical model of optimal operation of the micro-grid with multiple goals,the goal of grid operation optimization is analyzed from four aspects:economic benefits,environmental benefits,safety and reliability benefits,and user satisfaction.Combing with the constraints of the micro-grid and the treatment of the constraints,the commonly used intelligent algorithms are summarized for the optimization of the micro-grid′s multi-objective operation.The scientific and feasible theoretical guidance is provided for the optimization of the micro-grid operation,and it has a certain practical significance.
