The Strategy Of Classification Differentiated Price Of Electricity And The Management Of Interruptible Load

Nowadays, the traditional power supply mode can not accommodate with the rapiddevelopment of electric. It worth to reflect on how to ease the critical electricity supply,exploring the method of improving the efficiency of electric and decreasing the powerconsumption in the peak-load time.In Zhuhai, classification differentiated price of electricity just used in industry, andbrownouts happen frequently. The power demand side management is on junior level. Thispaper study on the strategy of classification differentiated price of electricity and themanagement of interruptible load in Zhuhai, analyses the formulation principles andoperational risk of the strategy. It turns out that the strategy has increased residentialelectricity consumption. Most residents are willing to consume more valley electricity, and theeffect of valley filling is comparatively obvious. This paper has also analyses the cost and thebenefit of the strategy of interruptible load, and set up the compensation mechanism of it. Itturns out that this strategy has leaded the consumers to shift peak load, eased the criticalelectricity supply in peak-load time. The strategy can also ensure the security and economicoperating of power gird.
