Abstract

Based on the adjustable characteristics of demand-side energy conversion and storage devices, the value of demand-side resources to improve the vulnerability of distribution network after power failure was analyzed. In order to maximize the effect of demand-side distributed energy on power grid load recovery, a two-stage optimization demand-side resource optimization selection model considering planning and operation was constructed. On the basis of considering different fault scenarios, the model aims to minimize the sum of system investment cost and off-load operation cost. At the same time, considering the constraints of user energy consumption and system operation, the demand-side resources can be used to evaluate the vulnerability of power grid by optimizing and selecting the callable demand-side distributed energy. A distribution network was selected as a case to analyze the effect of different demand-side resource optimization options on improving the vulnerability of the distribution network, and the effectiveness of the proposed method for supporting the rapid recovery of the distribution network was verified.
