蓄能调温负荷与光伏的智能化互动运行策略

为了充分利用蓄能调温负荷的调节资源,节约调温负荷的用电成本,并有效消纳光伏电量,提出了"光伏+调温负荷"的智能化互动运行策略。首先,建立了基于户型参数和天气信息的房屋冷、热需求模型;其次,以运行成本最小为目标,结合光伏出力和用冷、用热需求,在优先使用谷电电量的原则下,提出蓄能负荷与光伏供用电互动逻辑和运行策略;第三,以全年天气数据为驱动,按互动逻辑关系进行了全年运行累积计算的年运行成本分析。结果表明,互动运行模式相比于光伏与蓄能调温负荷独立模式的运行成本有很大降幅,"光伏+调温负荷"策略有效解决了光伏消纳和调温负荷电费的问题。这不仅有利于减少环境污染,还能够实现政府与用户的双赢。

Intelligent interactive operating strategy between photovoltaic and energy storage attemperation loads

In order to make full use of the adjustable resource of cold/thermal attemperation loads with storage energy (CTAL), and reduce electricity cost and consume of the photovoltaic (PV) energy, the interactive operation of "PV+CTAL" was proposed. Firstly, the model based on house parameters and weather data was established to analyze the cold/thermal demand, then interactive logics of operation in "PV+CTAL" was derived to minimize the cost of operation with prioritization of using valley electricity, considering the PV output and demand of cold/thermal. Finally, a scenario was presented to cumulatively calculate the annual operation cost according to the weather data and the interaction logical relationship. The results show that the operating cost in the "PV+CTAL" interactive mode is comparatively lower than that in standalone mode, the "PV+CTAL" interactive operating strategy can effectively solve the problem of the electricity price affected by PV consumption and CTAL, which not only will reduce environmental pollution, but also achieve win-win results with governments and users.
