An Operable Peak-Valley Time-of-Use Tariff Setting Method for Demand Side Management

The market effect of peak-valley time-of-use (TOU) tariff is researched by use of principles of economics and a mathematical model of peak-valley TOU tariff based on price elasticity matrix of electric power demand is built. A concept of reaction sensitivity of total network sale revenue against network load is proposed. By means of optimizing the objective function of the built mathematical model, an operable peak-valley TOU tariff setting method is obtained. Numerical simulation results show that the presented TOU tariff setting method is practicable and feasible, it is beneficial to reducing the peak load, improving the shape of load curve and enhancing the reliability and economy of power system operation as well as realizing the optimal arrangement of resources and the sustainable development of the power industry.
