用削峰填谷方法提高供电企业效益的分析

ANALYSIS OF IMPROVING PROFIT OF POWER SUPPLY ENTERPRISES BY PEAK LOAD SHIFTING

首先就削峰填谷在降低损耗方面的作用进行了分析,证明了削峰填谷使负荷曲线平坦对于降低损耗具有重要意义,且负荷曲线越平坦,降损效果就越明显。其次,简单分析了削峰填谷在延缓投资方面的作用。最后指出,在近年来峰谷差增大的情况下,加强需求侧管理,实行削峰填谷对于提高供电企业效益是非常重要的。

The action and importance of peak load shafting in reducing network loss is analyzed and it is proved that the more flat the load curve is, the more the network loss reduces. Then, the influence of peak load shifting on the lag in investment is preliminarily presented. Finally, the authors point out that under the increment of difference between the peak load and valley load in recent years, tightening up the DSM and peak load shifting are very important to improve the profits of power supply enterprises.
