Based on an analysis of the historical data and electricity consumption behaviors, customers' response to SOU price is first described by a price elasticity matrix of demand.

But these researches all established on the stage of elasticity analysis, the same characteristic period of response spectrum was used for the stage of elastoplastic analysis.

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.
