Demand Response Featured Dynamic Voltage Regulation of Active Distribution Network

This With high proportion of distributed power sources integrated into the grid, the active distribution network achieves the economic and safe operation of the grid through the comprehensive application of demand response. In this paper, a voltage optimization method based on demand response is proposed. According to the dynamic combination of interruptible and transferable load and dual energy storage, a day-ahead reactive power optimization model is established to minimize the voltage deviation of distribution network. The optimal decision variables include discrete and continuous, and the second-order cone method can linearize the mixed nonlinear model and simplify the model, so the mixed integer second-order cone programming model is used in this paper. The feasibility and effectiveness of the optimization model are verified by the improved IEEE 33-bus power distribution system.
