Research on Time-of-Use Tariff Optimization and Influencing Factors under the Background of New Electric Power System

Abstract

Under the background of new power system construction, this paper studies the optimization strategy of time-of-use (TOU) price, and provides a TOU price decision scheme for the operation of power market. Based on the price-based demand response (PBDR) strategy, the guiding effect of TOU price on users’ peak-valley reduction is fully considered. Therefore, this paper establishes a TOU price model with the minimum peak-valley difference as the optimization objective, and solves the model to obtain the optimal TOU price. Finally, the influence of power demand price elasticity, peak-valley time division and other factors on TOU price strategy is analyzed quantitatively, and relevant policy suggestions are put forward.
