Customer Reward-B ased Demand Response Program to Control Tie Line Power

Abstract

During the actual operation of micro grid, the power fluctuation of tie line caused by the Load power fluctuation of renewable energy or load prediction deviation needs to be controlled in real time to ensure the economy of micro grid operation. This paper aims at a power system model based on the framework of distribution network - industrial park micro grid - enterprise load user, and studies a power control method of micro grid tie line based on user reward scheme. Firstly, the objective economic function of the micro-grid in the park is established, and then the optimal reward scheme for internal load users of the micro-grid in the park is derived according to two typical load response models. The power fluctuation can be stabilized by encouraging load users to respond to demand, thus the internal load users can benefit while reducing their own economic losses and the day-ahead scheduling results of tie lines can be effectively tracked. Taking a production industrial park as an example, the effectiveness of the proposed optimization model and algorithm is verified by an example analysis.
