具有2种制冷方式的冷热电联产系统时序仿真算法
|
摘要
基于最优运行策略的分析,将具有2种制冷方式的冷热电联产系统的最优运行策略归结为5种运行策略,每种运行策略的设备出力可基于负荷平衡直接得到。提出了一种冷热电联产系统的时序仿真算法,该算法无需求解最优运行模型,实现了基于优化运行策略的仿真,具有明显的速度优势。基于实际系统的计算结果验证了所提算法的有效性。
Based on the analysis of optimal operation strategy,the optimal operation strategies of the CCHP(Combined Cooling,Heating and Power) system with two cooling modes are generally attributed to five operation strategies,and the equipment output of each operation strategy can be obtained directly based on load balance. A sequence simulation algorithm for CCHP system is proposed,which can realize the simulations based on the optimal operation strategies without solving the optimal operation model and has the obvious speed advantage. The calculative results of an actual system verify the effectiveness of the proposed algorithm.
