Management method of power interruptible load based on interruptible potential assessment

Abstract

The invention discloses a management method of a power interruptible load based on interruptible potential assessment. The management method comprises the following steps that the total power consumption Qi and the total operating profit Bi of the industry i of certain consecutive years, the typical daily average load of the typical user m and the maximum load during the peak period of the systemare acquired, and the typical user of each industry i is selected to perform questionnaire survey; the interruption intension index xi1, the power shortage loss index xi2, the load reduction ratio index xi3 and the peak daily load rate index xi4 of the industry i are acquired; the reference values of xi1, xi2, xi3 and xi4 are set; the corresponding weight omega1, omega2, omega3 and omega4 of xi1,xi2, xi3 and xi4 are determined; and the interruptible potential score ILPi of the industry i is calculated and the interruptible potential of the industry i is ordered. The industrial load interruptible potential evaluation index system is constructed by using the indexes of interruption intention, power shortage loss, load reduction ratio and peak daily load rate and the interruptible potentialof different industries is quantitatively compared so that the industry suitable for participation is preferentially selected.

Description

technical field [0001] The invention relates to the field of power demand side management, in particular to a method for managing power interruptible loads based on interruptible potential evaluation. Background technique [0002] my country's electricity market has shown a situation of oversupply of electricity in the past two years, but short-term electricity shortages will still occur during the peak summer period and system accidents in economically developed areas. Practices at home and abroad have verified that interruptible load management can effectively alleviate the periodical power shortage of the system and help to promote the optimal allocation of power resources. At present, most provinces in my country have not implemented interruptible load management, and the implementation areas have not considered the differences in load characteristics and production characteristics of different industrial loads. Most of the selected participating enterprises are black an...

Problems solved by technology

At present, most provinces in my country have not implemented interruptible load management, and the implementation areas have not considered the differences in load characteristics and production characteristics of different industrial loads. Most of the selected participating enterprises are black and non-ferrous industries with high energy consumption.
