基于需求侧响应的区域综合能源系统的低碳经济调度

Low-carbon Economic Dispatch of Regional Integrated Energy System Based on Demand Side Response

  • 摘要: 利用区域综合能源系统具有多能源互补及耦合的优势,能综合提升多种能源消纳的优化配置。提出一种区域综合能源系统的多目标低碳经济调度模型,充分挖掘区域能源系统内的储热装置、电锅炉和电储能促进风电并网消纳的优势。此外,综合考虑电价弹性变化、温度变化的影响,建立了负荷弹性需求响应机制,降低了系统负荷的峰谷差水平,进一步提升风电的上网空间。最后,利用改进精英策略下的NSGA-Ⅱ算法对所提调度模型进行优化求解。通过仿真结果说明了考虑峰–谷分时电价及储热、储能和电锅炉装置均能提升风电进一步并网消纳的空间,有利于优化区域综合能源系统内的低碳调度指标。最后结合IEEE-39标准节点电力系统和一个7节点的热力系统验证了所提模型的合理性。

     

    Abstract: The use of regional comprehensive energy systems has the advantages of multi-energy complementation and coupling, and can comprehensively improve the optimal configuration of various energy consumption. This paper proposes a multi-objective low-carbon economic dispatch model for a regional integrated energy system, which fully exploits the advantages of heat storage devices, electric boilers and electric energy storage in the regional energy system to promote wind power grid-connected consumption. In addition, the influence of electricity price elasticity changes and temperature changes is taken into consideration, and a load elasticity demand response mechanism is established, which reduces the peak-to-valley difference of system load and further improves the online space of wind power. Finally, the NSGA-II algorithm under the improved elite strategy is used to optimize the scheduling model. The simulation results show that considerations of the peak-valley time-of-use electricity price and heat storage, energy storage and electric boiler installations can increase the space for further grid-connected wind power consumption, which is conducive to optimizing the low-carbon dispatch indicators in the regional comprehensive energy system. The IEEE-39 standard node power system and a 7-node thermal system are used to verify the rationality of the proposed model.
