一、引言众所周知,空调用电十分惊人,仅以广东省为例,目前空调装机容量已达30万千瓦,并以30％的速度猛增,空调用电量已占用电总量的40％以上。但是,由于昼夜气温变化,工作时间安排等因素,电力负荷的分配是白天“峰值”时间不够用,晚上“谷底”时间用不完,为了调峰填谷,国家甚至投资16亿元巨资兴建从化扬水站进行电网调荷,同时在用 I. INTRODUCTION As we all know, air conditioning power consumption is very alarming, only in Guangdong Province, for example, the current installed capacity of air conditioning has reached 300,000 kilowatts and 30% surge in air-conditioning electricity consumption has accounted for more than 40% of total electricity . However, due to changes in day and night temperatures and working hours, the distribution of electricity load is not enough during the daytime peak time and not enough time at the bottom of the valley. In order to peak-fill the valley, the state even invested a huge sum of 1.6 billion yuan Conghua pumping station for power transfer network, while in use
