【摘要】：蓄冷可以通过利用峰谷电价差,使空调系统更加经济,还可以作为一种间接蓄电措施,在峰电时段释放冷量,减少空调系统耗电,实现削减用电峰值功率的功能。对工业园区内需要24 h供冷的、包含基载的蓄冷空调系统的控制进行优化建模,在满足供冷及削峰需求条件下,以经济最优化为目标,分别针对非削峰日、2类削峰日提出相应的控制策略。并以工业园区某一水蓄冷空调系统的控制为例进行了算例分析,结果表明蓄冷空调在削峰时具有削峰幅度大、削峰时间长的优势。另外,当该日冷负荷需求越大时,2类削峰日对蓄冷空调系统运行费用的影响越大,此时可能需要增加削峰补贴电价。
[Abstract]:Cold storage can make the air conditioning system more economical by using the difference of peak and valley electricity price. It can also be used as an indirect power storage measure to release the cooling capacity in the peak period, reduce the consumption of electricity in the air conditioning system, and realize the function of reducing the peak power of the air conditioning system. The optimal modeling of the control of the air conditioning system which needs 24 hours of cooling and including base load in the industrial park is carried out. Under the condition of satisfying the demand for cooling and cutting the peak, the economic optimization is taken as the goal, respectively, for the non-peak cutting day. Two kinds of peak-cutting days are put forward corresponding control strategy. Taking the control of a water storage air conditioning system in an industrial park as an example, the results show that the storage air conditioning has the advantages of large peak cutting amplitude and long peak cutting time. In addition, the higher the demand for the cooling load, the greater the impact of the two kinds of peak-cutting days on the operating cost of the air conditioning system, and it may be necessary to increase the peak-cutting subsidy price.
