摘要
将区域内多个单微电网互联构成多微电网系统是解决单微电网运行所面临诸多问题的有效方式之一。本文提出一种基于改进双向拍卖的多微电网能量协调优化调度模型。该模型首先以多微电网系统的综合成本最小为目标,优化计算各微电网与其他微电网和配电网的交互功率之和;其次,基于改进的双向拍卖买卖模型,协调微电网与其他微电网和配电网间的交互功率分配,满足各微电网的供需平衡,通过多微电网间的能量交互降低系统运行成本并减少对配电网系统的影响。算例结果表明,多微电网系统内能量互济,总运行成本降低,由此验证了所提出模型的有效性与经济性。
The formation of a multi-microgrid system is one of the effective ways to solve the problems with the operation of single microgrids in an area.In this paper,a coordinated optimization scheduling model for energies in multi-microgrid is proposed based on improved double-auction.First,the minimum comprehensive cost of the multi-microgrid system is taken as the objective,and the sum of power interactions between each microgrid and other ones and distribution network is optimized.Second,based on an improved double-auction trading model,the interactive power distribution between the microgrid and other ones and distribution network is coordinated to strike a balance between the supply and demand of each microgrid,and the system’s operating cost and the impact on distribution network system are reduced through energy interactions among multiple microgrids.The result of a numerical example show that energies in the multi-microgrid system can compensate each other at a lower total operating cost,which verifies the validity and economic efficiency of the proposed model.
