摘　　要：基于建筑具有储能特性,该优化运行策略提前启动空调系统,其启动时间由BP模型预测得到,并将冷量储存于围护结构。在峰值电力期间,利用较低的围护结构表面辐射温度,在保证舒适性前提下,提高室内温度设定值。最后在TRNSYS仿真平台上对该运行策略进行仿真验证,并与常规运行方法进行比较。得出结论:该方案不仅达到了移峰添谷的目的,同时也有效地保证了室内舒适性。Based on the character of building energy storage, this paper gets the pre-cooling time through BP model, Before peak load＇s coming, walls store cooling energy, Once it comes, the temperature set point will be reset higher according to the lower radiation temperature of walls, but the comfort won＇t be affected. In the end, the strategy is simulated on TRNSYS. Comparing with normal strategy, it could be concluded that this strategy gains the ends of shifting the peat load. At the same time, it also keeps comfortable indoor.
