Suppose that it is random factors not system factors that bring about money supply fluctuation, then the appropriate range of money supply and the warning limit of fluctuation can be determined with statistical methods.It comes to the conclusion that the deviation of money supply from money demand is due to the range of [-0 18,0 18] and if the fluctuation approaches or goes beyond the range,regulation measures must be taken as soon as possible.展开更多
针对我国北方地区供暖季经常出现过热或过冷现象以及大量的弃风的现象,本文基于MATLAB/Simulink平台,建立供暖系统。该系统模型从用户出发,根据室外温度的变化,在负荷侧引入表征人体热反应的评价指标(Predicted Mean Vote,PMV)反映出用...针对我国北方地区供暖季经常出现过热或过冷现象以及大量的弃风的现象,本文基于MATLAB/Simulink平台,建立供暖系统。该系统模型从用户出发,根据室外温度的变化,在负荷侧引入表征人体热反应的评价指标(Predicted Mean Vote,PMV)反映出用户的用热舒适度,从而确定负荷侧的供热区间,以风电功率使室内温度维持在舒适区的区间内,及时调整供回水温度,保证居民的满意度的同时,增加风电上网空间。展开更多
