摘要:

综合能源系统与上级电网进行能量交互用以满足系统内的负荷需求,但系统的用能特性也加剧了电网的峰谷现象。为发挥综合能源系统的调峰作用,引入分时电价调节策略,用来优化设备在不同时段下的出力,满足系统经济高效运行,同时又能缓解电网的峰谷矛盾。构建了园区系统的优化调度模型并进行求解,得到的结果对综合能源系统的最优化运行具有指导意义。同时,为了比较不同求解方法之间的异同点,分别采用混合整数规划法和粒子群算法进行求解,得到了不同方法之间的差异,可对未来的研究提供参考。

Abstract:

The integrated energy system exchanges energy with the grid to meet the load demand within the system.Meanwhile,the energy consumption characteristics of the system aggravate the peak valley phenomenon of the power grid.In order to play the role of peak load regulation of integrated energy system,this paper introduces time of use price regulation strategy,which is used to optimize the output of equipment in different periods.It can not only meet the economic and efficient operation of the system,but also alleviate the peak valley contradiction of the power grid.To this end,the optimal scheduling model of the park system is constructed and solved in this paper,and the results obtained can guide the optimal operation of the integrated energy system.At the same time,in order to compare the similarities and differences between different methods,two types of typical methods,the mixed integer programming method and particle swarm optimization algorithm,are used to solve the problem,which can provide a reference for future research.

Key words: integrated energy system, time of use price, multi energy coupling, intra-day optimization
