摘要
针对当前纯电微网运行效率较低,且单独参与市场交易时缺乏竞争力等问题,构建了考虑微网间电能交互的多微网联合调度模型。首先,构建含冷热电联供(combined cooling heating and power,CCHP)系统的微网基本调度模型,并通过“以热/冷定电”的方式提高微网调度策略的灵活性;其次,考虑到微网间可直接进行点对点(peer to peer,P2P)交易,建立了考虑P2P交易的多微网联合调度模型;最后,对一个市场运营商与三个CCHP型微网的案例进行仿真。结果表明,所提出的调度方式进一步降低了系统的运行成本。
Aiming at the problems of low operating efficiency of current pure electric microgrids and lack of competitiveness when participating in market transactions alone,a multi-microgrid joint dispatch model that considerd the interaction of electrical energy between microgrids was conceived.Firstly,build a basic microgrid dispatch model with a combined cooling heating and power(CCHP)system,and improve the flexibility of microgrid dispatching strategies through the“heat/cold fixed power”approach;secondly,considering that peer-to-peer transactions can be conducted directly between microgrids,a multi-microgrid joint scheduling model considering P2P transactions was established;finally,a case of a market operator and three CCHP-type microgrids was used for simulation.The results show that the proposed scheduling method further reduces the operating cost of the system.
