摘要:

为充分挖掘多能互补能源系统“源-荷”协同调峰潜力,提出需求响应与热泵联合调峰的区域综合能源系统经济调度方法。源侧引入天然气热泵,通过多能互补进行供能替代以充分发挥电-气能源互补特性,削减电力高峰空调设备运行负荷;荷侧考虑电价需求响应,将用户用电满意度融入需求响应模型中,计及用户用电体验对电力需求进行优化,以实现电力负荷“削峰填谷”。以最小化系统运行成本为目标,综合考虑能量平衡、需求响应约束等,在优化软件CPLEX中进行求解。算例研究表明,源荷协同调峰能够有效降低用电高峰系统电力需求,提高系统运行经济性。

Abstract:

In order to fully tap the potential of “source-load” coordinated peak shaving of the multi energy complementary energy system,an economic dispatch method of regional integrated energy system based on demand response and heat pump joint peak load shaving is proposed.On the source side,the gas heat pump is introduced and the energy supply is replaced by multi energy complementarity to give full play to the complementary characteristics of electric-gas energy,thus reducing the operation load of the peak air conditioning equipment.Considering the price-based demand response,the load side integrates the user’s power consumption satisfaction into the demand response model,and optimizes the power demand taking into account the user’s power consumption experience so as to realize the “peak shaving and valley filling” of power load.The model is established to minimize the system operation cost and solved by the optimization software CPLEX comprehensively considering the energy balance and demand response constraints,etc.The case study shows that the source-load coordinated peak load shaving can effectively reduce the power demand of the peak power system and improve the economics of system operation.

Key words: regional integrated energy system, gas heat pump, demand response, peak load shaving, economic dispatch
