摘要
为促进电热综合能源市场多能流协同消纳,减少负荷不平衡所带来用能波动的问题,基于价格弹性矩阵建立电、热需求响应模型,以能量枢纽为利益主体,利用均衡约束数学规划模型,制定综合能源市场竞标策略。实现电、热网运营商运行成本最小的同时,使能量枢纽运营主体获得最大收益,并且有效降低系统总耗能。结果表明,系统在综合需求响应机制的作用下削峰填谷、平衡系统用能,以能量枢纽获益降低160.44元为代价,换取减少能耗2.3 MW,且冬夏两季能量枢纽收益和系统整体能耗百分比变化较小,分别为3.42%和0.604%。
This paper is an attempt to promote the synergistic consumption of multiple energy flows in the electricity and heat integrated energy market for reducing the problem of energy consumption fluctuating in use caused by load imbalance.The study involves establishing an electricity and heat demand response model based on the price elasticity matrix;by taking an energy hub as the main body of interest,utilizing an equilibrium constraint mathematical planning model to formulate a bidding strategy for the integrated energy market.While minimizing the operating costs of the electric and thermal network operators,the energy hub operator obtains the maximum benefit and effectively reduces the total energy consumption of the system.The results show that the system can balance the system energy consumption under the integrated demand response mechanism by reducing energy consumption by 2.3 MW at the cost of reducing energy hub benefits of 160.44 RMB,and the changes of the percentages of energy hub benefits and overall system energy consumption in winter and summer are relatively smaller by 3.42%and 0.604%,respectively.
