摘要
家庭微网作为电力用户侧需求响应的综合平台,在考虑经济运行的同时也注重用户的舒适度。针对家庭微网中用电负荷季节性差异,以及家庭微网中储能容量的差异带来运行成本的不同,以年为周期进行家庭微网的建模与仿真更为合理,同时为家庭微网规划出一个最优的储能系统容量。以蓄电池充放电功率和可调度负荷功率为优化变量,建立不同偏好因子下家庭微网年总运行费用最低模型,最后通过遗传算法优化得到不同偏好因子下家庭微网中最优储能容量及年最优运行费用。仿真结果表明,该模型能够满足不同偏好因子下家庭微网的最优运行。
As a comprehensive platform of response on the demand of power user side,household microgrid pays attention to the comfort of users while considering the economic operation.According to the seasonal difference of electricity load in the household microgrid and the difference of energy storage capacity in the household microgrid,it is more reasonable to conduct the modeling and simulation of the household microgrid on an annual basis,and to plan an optimal capacity of energy storage system for the household microgrid.Considering the battery charge and discharge power and schedulable load power as optimization variables,the annual total minimal operation cost model for the household microgrid is set up under different preference factor.Finally,optimal capacity of energy storage and optimal operating cost of the household microgrid under different preference factor is obtained by genetic algorithm.The simulation result shows that the model can reliably meet the optimal operation of the household microgrid under different preference factor.
