针对目前综合能源系统(integrated energy system,IES)因设备种类繁多而优化调度困难、综合能源利用效率较低的问题,提出一种基于广义储能(generalized energy storage,GES)的综合能源系统优化调度模型.首先建立各类不同负荷的GES模型,简化了能源调度与消费之间的信息交互,然后基于GES模型建立了日前和日内优化调度模型,为IES能量流分析和优化提供有效途径,最后搭建IES仿真测试系统验证了所提模型的有效性.仿真测试结果表明,该优化模型能充分挖掘负荷的调度潜力,缓解能源调度供需平衡的压力,降低电力系统的运营成本,减少协同分析计算的时间,提升优化调度方法的计算精度和效率.
Optimal Scheduling Model of Multi-Time Scale Integrated Energy System Based on Generalized Energy Storage
Aiming at the problems that the integrated energy system(IES)is difficult to optimize and scheduling due to the wide variety of equipment,and the utilization efficiency of comprehensive energy is low,an integrated energy system optimization schedul-ing Model based on generalized energy storage(GES)is proposed.Firstly,GES models of various loads are established,which simplify the information interaction between energy scheduling and consumption.Then,based on the GES model,day-ahead and intra-day optimal scheduling models are established to provide an effective way for IES energy flow analysis and optimization.Finally,IES simulation testing system is built which verifies the effectiveness of the proposed model.The simulation test results show that the optimization model can fully tap into the scheduling potential of the load,relieve the pressure of energy scheduling sup-ply and demand balance,reduce the cost of power system,reduce the time for collaborative analysis and calculation,and improve the calculation efficiency and accuracy.
