摘要
多能联供综合能源系统有利于推动能源转型、实现多能源协调互补,已成为能源互联网的重要发展方向。针对以可再生能源为主体的冷热电联供问题,引入热电联产型光热(concentrated solar power,CSP)电站作为核心供能单元,并结合电加热器、吸收式制冷机、地热源热泵等能量转换设备组成综合能源系统(integrated energy system,IES),提出一种冷热电联供型IES运行优化方法。首先构建了IES架构,并建立了光热电站与建筑物热平衡模型。然后,引入居民舒适度惩罚项,建立了考虑运行成本的IES经济优化模型。在此基础上,建立计及多重不确定性的IES模糊机会约束规划模型。最后,通过算例仿真验证所提策略可以满足居民的不同舒适性需求与提高光热电站的供能潜力,降低系统的运行成本。
As an important development direction of energy internet,multi-energy supply integrated energy system(IES)is conducive to promoting energy transformation and achieving the coordinated complementation of multiple energy resources.Aiming at the problem of combined cooling,heating and power(CHP)mainly based on renewable energy,the paper introduces CHP concentrating solar power(CSP)plants to act as core energy supply units.The energy conversion facilities such as the electric heater(EH),the absorption chiller(AC)and the ground source heat pump(GSHP)equipped are combined to form an integrated energy system(IES),and an operational optimization method of IES for combined cooling,heating and power is put forward.Firstly,the paper constructs the IES framework and establishes the model of CSP plant and building heat balance.Then,a resident comfort penalty is introduced.An IES economic optimization model where the operating costs are taken into account is established.On this basis,an IES fuzzy chance constrained programming model is formed after considering multi-uncertainty of the system.Finally,the simulation results show that the strategy can meet the different requirements of residents for comfort and improve the energy supply potential of CSP plant,and reduce the operational cost of IES.
