江苏某市夏季典型日电力负荷曲线
但:①工业结构正在调整,粗放式有序用电 社会影响大,无法保证公平
空调等非生产性负荷具有明显的季节性和时段性特点,与电网峰谷差具有强关联性,导致 电网最高负荷95%以上仅为70~80小时。国家每年需投入巨资用于电厂和电网的建设,造成了 社会资源的极大浪费。
Air conditioning and other non-productive loads have obvious seasonal and time characteristics, and a strong correlation with the peak-valley difference. The length of time when loads in the system reaches 95% of the maximum load is short, only 70 to 80 hours. China has to invest heavily in power plants and power grid construction, which is a great waste of sources.

峰谷差逐年增大。2015年江苏电网空调负荷为2700万千瓦,接近当年最高负荷的1/3;最大
峰谷差亦接近2100万千瓦,约占最高负荷的1/4。

②新建机组投资大,运行效率低
总体来看,在新形势下: 随着社会经济的不断发展和电力市场改革的不断深化, 原先以政府行政命令式手段进行负荷调控的方式已越来越不适用,政府 开始着手研究通过市场化的需求响应等技术手段实现负荷调控。

Solution
•Power plants: new generators •System:peak load units •governments: orderly electricity consumption •consumers: energy saving
However: ①Industrial structure is being adjusted, extensive electricity saving has large impact on society, which can not guarantee the fairness. ②New units need large investment and operating efficiency is low.
