Real-time price responding method in distribution network based on smart loads

Abstract

In order to deal with the real-time power imbalance problem as the integration of renewable energy, and guide users to optimise power consumption, the real-time price technology has been gradually introduced into the demand management of distribution network. However, the response to real-time price is still highly dependent on the artificial switching on/off loads, the intelligent level of which needs to be improved urgently. To solve this problem, improve the response speed and response degree of loads, an intelligent real-time price responding method based on smart loads is proposed. First, the basic principles of smart loads are analysed. After that, the control strategy and control loop which can make smart loads realise the automatic response of real-time price are designed. At last, verified by the simulations conducted in MATLAB/Simulink, the real-time price responding method proposed here is reliable and effective, and the real-time price responding speed and responding degree of loads can be greatly improved.
