Optimized Planning on Reactive Power Compensation of Distribution Network Based on Linear Programming Algorithm

As the optimization of reactive power compensation plays a key role in planning and design of the distribution network, the chief considerations of optimization targets are the minimum transmission loss ,the minimum investment and the maximum overall economic efficiency, adopting different reactive configuration planning according to different targets. A mathematical model is built in accordance with linear programming method of distribution network. It makes the maximum overall economic efficiency as the objective function, takes reactive power balance and voltage qualification as constraints and combines the optimization of reactive power flow. Through repeatedly using the iterative method after calculating the operating parameters, we obtain reactive power optimization.
