摘要

针对微电网静态经济调度忽略了各时段之间内在联系的不足，考虑风电机组、光伏电池以及钠硫电池等不确定性因素对经济调度的影响，以微电源出力和微电网运行成本最小为目标函数，建立了微电网动态经济调度模型。采用VC++编制了利用改进微分进化算法的微电网动态经济调度程序，通过改变动态交叉因子，提高了算法的收敛速度和防止陷入局部最优的能力。根据微电网算例结构的特点，分别针对微电网孤网/并网运行情况，制定了微电源的出力原则和运行控制策略。计算结果表明，采用动态优化理论的微电网经济调度较静态调度在成本节约上更具优势，也使得钠硫电池的充放电更具有全局性和实际意义。

Abstract

In order to deal with the shortcomings of static economical dispatch for microgrid ignoring the inherent link between the intervals，by considering the influence of wind turbines，photovoltaic cells and sodium sulfur battery on economical operation，and with micro power output and power operation minimum cost as objective function，a dynamic economical dispatch model for microgrid is proposed.A VC++ procedure for microgrid dynamic economical dispatch using the improved differential evolution algorithm is compiled.By improving the parameters set of the algorithm，the convergence speed and ability of preventing the algorithm from falling into local optimum are enhanced.According to the characteristics of the microgrid structure of calculation，the grid-isolated/grid-connected mode operation output principle of the micro-source and control strategy of typical microgrid structure are formulated.The results show that the dynamic economical dispatch model for microgrid has more advantages than static scheduling in cost saving，and is more global and practical for sodium sulfur battery charge and discharge.
