摘要 综合能源系统是提高能源利用率的有效途径之一。该文针对园区级电-热综合能源系统,考虑综合需求响应与条件风险价值,建立了相应的日前经济调度模型。首先,建立包含燃气轮机、分布式能源机组、储热装置、热泵以及电热负荷的园区电-热综合能源系统稳态数学模型;然后,提出适用于电力负荷、民用供暖热负荷与工业热负荷的激励型综合需求响应模型;最后,利用条件风险价值分析新能源出力与负荷预测不确定性的风险,以运行成本最低为目标函数,建立日前经济调度模型。对英国百利岛电-热综合能源系统进行了算例分析,结果表明,综合需求响应的加入可以提高系统的能源利用率,降低系统的运行成本,而条件风险价值的加入则可以有效平衡调度策略的安全性与经济性。

Abstract:Integrated energy systems are one of the effective ways to improve energy utilization efficiency. This paper establishes a day-ahead dispatch model of regional electricity-heating integrated energy systems considering integrated demand response and conditional value-at-risk. Firstly, a steady model of electricity-heating integrated energy system consisting of gas turbines, distributed renewable energy resources, heat storage tanks, heat pumps, electrical and heating loads was established. Secondly, incentive integrated demand response models applicable for electrical loads, heating loads and industrial heat loads were proposed. Finally, conditional value-at-risk was used to analyze the risks of renewable energy outputs and load forecast uncertainties, and an optimization model with the objective of minimizing system operation cost was established. Effectiveness of the proposed model was verified by a case study of Barry Island integrated energy system and the results illustrated that the addition of integrated demand response can improve system energy utilization efficiency, reduce system operation costs while conditional value-at-risk can balance the safety and economy of day-ahead dispatch.
