Virtual power plant energy management method and device based on micro-grid dispatching

The invention discloses a virtual power plant energy management method based on micro-grid dispatching, which takes cost reduction and income improvement as optimization objectives, considers constraint conditions such as upper and lower limits of output, electricity price, electric quantity and the like, and establishes a game model in which a plurality of virtual power plants participate in bidding and income distribution. According to the method, the artificial bee colony algorithm is improved and prevented from falling into local optimum, and the improved artificial bee colony algorithm is used for solving the established game model, so that the convergence speed is increased. According to the invention, the earnings in the internal bidding process of the virtual power plant are improved. 本发明公开了一种基于微电网调度的虚拟电厂能源管理方法，以降低成本、提高收益为优化目标，计及出力上下限、电价、电量等约束条件，建立了多个虚拟电厂参与竞价与收益分配的博弈模型。对人工蜂群算法进行了改进，避免其陷入局部最优，利用改进后的人工蜂群算法对建立的博弈模型进行求解，提高了收敛速度。本发明提高了虚拟电厂内部竞价过程中的收益。
