Based on the price elasticity matrix

the method to implement peak-valley and time-of-use and season-of-use price is explored to consist with electricity consumers’ response of different industries. Through the establishment of the season-of-use price elasticity matrix and time-of-use price elasticity matrix for each industry

the cost function and profit function for each industry are created according to the investigation data of electric power consumers. By solving the two functions’ cross point

the needed adjustment ratios for each industry electricity consumers when achieving the electricity quantity shift limit with the electricity quantity shift cost restraint are obtained. At last

the proposed method is applied to Yunnan power system. The application results show the larger price adjustment quantity differences among the different industries when achieving the electricity quantity shift limit

and the necessity to implement different peak-valley and time-of-use and season-of-use prices in view of different electricity consuming characteristics of every industry.
