【摘要】：灵活互动的智能电网鼓励用户侧与电网的积极互动,在互动中促进用户与电网企业的互利共赢。实时电价可作为电网企业发布系统调节需求的一种方式。同时,光伏系统、储能系统与电动汽车为家庭积极响应电网调节提供了可能。在实时电价的环境下,在含有光伏系统、储能系统和电动汽车的家庭微电网中,以蓄电池和电动汽车作为家庭中参与能量优化的主要对象,首先建立了蓄电池的充放电模型和电动汽车的充电模型;其次建立了以家庭微电网系统总运行费用最小为目标的能量优化模型,并采用了混合整数线性规划法对模型进行了求解。最后仿真验证,该模型能够有效地减少系统运行费用。
[Abstract]:The flexible and interactive smart grid encourages the active interaction between the user side and the power grid, and promotes the mutual benefit between the user and the grid enterprise in the interaction. The real-time electricity price can be used as a way for the grid enterprise to issue the system regulation demand. At the same time. Photovoltaic systems, energy storage systems and electric vehicles provide the possibility for families to respond positively to grid regulation. In the real-time electricity price environment, in the home microgrid with photovoltaic system, energy storage system and electric vehicle. Taking battery and electric vehicle as the main objects of energy optimization in the family, the charging and discharging model of battery and the charging model of electric vehicle are established firstly. Secondly, the energy optimization model with the minimum total operating cost of the household microgrid system is established, and the hybrid integer linear programming method is used to solve the model. Finally, the simulation is carried out. The model can effectively reduce the operating cost of the system.
