    摘要:

    为提高综合能源系统对新能源的消纳能力,降低系统运行成本。本文以工业园区综合能源系统为研究对象,提出了一种考虑综合需求响应的优化调度模型。首先,建立了包含CHP机组、燃气锅炉、电锅炉等耦合设备的园区综合能源系统基本模型,并将系统需求侧柔性负荷分为可转移、可中断、可替代负荷三种,其中可替代负荷实现了多类能源之间的协调互动。其次,讨论了需求侧灵活资源电动汽车的可调度价值,结合系统分时电价以及负荷曲线,有序引导电动汽车充放电以参与综合能源系统的优化调度。最后,进行了实例分析,验证了所提模型在运行成本、消纳新能源以及“削峰填谷”等方面的优势。

    Abstract:

    In order to improve the ability of integrated energy system to absorb new energy and reduce system operating cost. This paper takes the integrated energy system of industrial park as the research object, and proposes an optimal scheduling model considering the integrated demand response. Firstly, the basic model of the park integrated energy system including CHP unit, gas boiler, electric boiler and other coupled equipment was established, and the flexible loads on the demand side of the system are divided into three types: transferable loads, interruptible loads, and replaceable loads. Among them, replaceable loads have realized the coordination and interaction between multiple types of energy. Secondly, the schedulable value of electric vehicles is discussed, combined with the time-of-use electricity price and load curves of the system, the charging and discharging of electric vehicles are orderly guided to participate in the optimal scheduling of integrated energy system. Finally, an example analysis was carried out to verify the advantages of the proposed model in terms of operating cost, consumption of new energy and peak loads shaving .
