摘要
基于电负荷及热负荷在综合能源系统中均存在供应峰谷压力而具备可调控价值,从公共建筑能源需求侧出发,结合供应侧的热、电分层优化,提出了考虑电、热综合需求响应的的公共建筑综合能源系统优化模型。首先从需求侧出发,建立传统电负荷需求响应模型,并结合人体对于温度的不敏感性建立公共建筑热负荷需求响应模型;其次建立含有微燃机、燃气锅炉、光伏、制冷机、储能装置等设备的综合能源系统模型;然后从供应侧角度,以综合能源供应成本最低为目标提出热、电分层优化模型。通过仿真算例可知,综合需求响应的应用从需求侧降低了用户用能需求和系统峰谷差压力,有效提升了系统运行灵活度,可为系统带来显著的经济效益。
Based on the existence of supply peak and valley pressures in the integrated energy system for electrical and thermal loads,it has controllable value.Starting from the energy demand side,combined with the optimization of the heat and electricity stratification on the supply side,the optimization model of the integrated energy system for public building was proposed,which takes into account the comprehensive demand response of electricity and heat.From the demand side,the traditional electrical load demand response model was established.Based on the traditional model,the thermal load demand response model was established in combination with the insensitivity of the human body to temperature.The integrated energy system model was established,including micro-turbine,gas boiler,photovoltaic,refrigerator,energy storage device.From the perspective of supply side,the optimal model of heat and electricity stratification was proposed with the goal of lowest comprehensive energy supply cost.Through simulation examples,it can be seen that the application of comprehensive demand response reduces the user’s energy demand from the demand side and the peak-valley pressure of system,which effectively improves the flexibility of the system operation and brings the significant economic benefits to system.
