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

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.
