Reactive power optimization of active distribution network with wind-photovoltaic-energy storage hybrid system
In order to improve the utilization rate of wind and light energy and reduce the impact of its output volatility on the distribution network, the active distribution system model with Wind-Photovoltaic- Energy Storage Hybrid System is established by using the complementarity between wind and solar energy time and space and the effect of energy storage device on power. With the reactive compensation device as the optimization variable, multi-time dynamic reactive optimization of the active distribution network is established, the multi-objective optimization model with the lowest network loss and voltage deviation is established, and the optimization model is converted into a mathematical planning form with convex feasible domain by using the second-order cone relaxation technology. Finally, the IEEE33 node distribution system is verified, the distribution network with different types of distributed power generation methods is reactiveoptimization, the role of the active distribution network pressure control and loss reduction is compared with the analysis, and the wind-photovoltaic-energy storage hybrid system is analyzed. Finally, the accuracy and reliability of second-order cone planning relaxation technology are verified.
