摘要
建立带蓄能装置的分布式冷热电联产系统优化运行的数学模型,分析系统应用常规优化方法和敏感性分析法时各设备的运行策略。针对典型案例的分析表明:通过敏感性分析法的应用,可以解明蓄能装置蓄释状态的变化对系统运行策略产生的影响,在没有额外增加系统日运行能耗费用的情况下,蓄能装置可在更稳定的状态下进行蓄能或释能,减少因蓄释能策略大幅度的变化给装置本身带来的负担,有利于延长其使用寿命。
A mathematical model for optimal operation of the combined cooling heating and power system integrated with energy storage facility is established. Following which,the operation strategies of main devices based on the conventional optimization method and the sensitivity analysis method are examined. The simulation results indicate that,the application of the sensitivity analysis method can illustrate the effect of changes of energy storage status on operation strategies of the whole system. In addition,the energy storage facility can operate at a more stable state with no additional increase of system operating costs. Therefore,the introduction of sensitivity analysis method may reduce the burden of significant changes of the energy storage operational strategy on the facility and it is conductive to extend the working life of the facility.
