摘要：
IES(Integrated Energy System) integrating cooling, heating, electric and gas energies is an effective means to enhance the efficiency of energy utilization and the local accommodation of renewable energy sources. MEP(Multi-Energy Park) is of typical IES and its dispatch strategy is worth researching. Models are established for the supply side, demand side and transmission side of MEP. At the demand side, a strategy of CAUR(Complementarily-Aggregative User Response) without influencing user's comfort degree is proposed based on the analysis of the internal relationship of energy coupling among users. At the transmission side, a HTTD(Heat Transmission Time-Delay) model of annular heat network is developed to improve the benefit of MEP operator and enhance the local accommodation of wind power, for which, a two-stage short-term optimal dispatch strategy is proposed to complementarily take the advantages of CAUR and HTTD. A multi-scenario simulative analysis is conducted for an MEP of 6-node electric network and 5-node thermal network, and results show that, with the consideration of HTTD, the cooperation between supply and demand sides is more effective and the performance of CAUR in the intra-day dispatch more outstanding;the two-stage optimal dispatch strategy combining day-ahead and intra-day optimal dispatch strategies can increase the benefit of MEP operator and enhance the local accommodation of wind power. © 2017, Electric Power Automation Equipment Press.
