Cost-Benefit Assessment Method for Demand Response Participating in Power Balance

doi:10.11930/j.issn.1004-9649.202102018

Abstract

Abstract: The balance of power supply and demand is a key problem in power planning. During the “14th Five-Year Plan” period, China's energy consumption will continue to grow rigidly, and the pressure of energy supply will continue to exist. With the increase of power load such as cooling and heating, electric vehicle charging and so on, the peak load of power grid becomes more prominent, which brings new challenges to power balance. Integrating demand response into power balance is a new way to solve the power balance problem, which can improve the investment efficiency of power planning. Based on an introduction of the basic methods for demand response participating in power balance, a cost-benefit assessment method for demand response participating in power balance is proposed, and its feasibility and effectiveness is verified through a case study. The results show that the economy of demand response participating in power balance is related to the subsidy standard and the proportion of demand response. The net economy decreases with the increase of subsidy standard, and firstly increases and then decreases with the increase of the proportions of demand response, and the optimal proportion of demand response for power balance is that when the net economy decreases to zero.

Key words: demand response, power balance, cost-benefit assessment, power planning
