Abstract: In this paper, an automatic response method for user side demand under centralised low-voltage load shedding is proposed. The centralised low-voltage load shedding algorithm is used to control the implementation sensitivity of the power system circuit. The time of use price model is built to calculate the price elasticity of power demand, and the K-means algorithm is used to build the power price model. The target function of automatic response on the user side is designed to realise automatic response on the user side. The experimental results show that the power supply of the proposed method is close to the actual power consumption, with the highest degree of user satisfaction of 98.3% and the highest degree of benefit optimisation of power supply companies of 16.3%, which can meet the needs of users, effectively regulate the power consumption and ensure the stability of the power system.

Keywords: centralised low-voltage load shedding; side demand; automatic response; time-of-use tariff; power load.
