摘要: 文章针对计及风、光、储的微电网系统,首先分析微电网系统的框架并对系统内各模块进行数学建模,接着对可调整负荷、可平移负荷分别进行柔性负荷特性研究并建模,采用NSGA2多目标优化算法,以微电网运行费用与储能系统的使用寿命为目标函数,研究微电网的日前优化调度策略,最后通过实例验证了算法的可行性与有效性。文章提出的日前优化调度方法与常规运行方案相比,通过对负荷的优化调度有效降低微电网的运行费用,同时提高储能系统的使用寿命,保证微电网安全、经济运行。
Abstract: This paper considers wind, solar and storage in micro grid system. Firstly, the framework of micro grid system is analyzed and the mathematical models of each module in the system are established. Then the flexible load characteristics of adjustable load and translatable load are studied and modeled respectively. Finally, the NSGA2 multi-objective optimization algorithm is adopted to study micro grid operation cost and the service life of energy storage system as the objective function. An example is given to verify the feasibility and validity of the algorithm. Compared with conventional operation schemes, the method proposed in this paper can effectively reduce the operation cost of micro grid by optimizing load dispatch, and improve the service life of energy storage system to ensure the safe and economic operation of micro grid.
