Reactive Power Optimization in Regional Power Grid

The paper analyzes reactive power optimization of regional power grid, and it establishes the mathematical model of power system reactive power optimization, taking minimizing annual operating cost as an object function, at the same time, considering the power factors and constraints of load bus voltage amplitude. It uses the MATLAB optimization toolbox quadratic function to optimize compute, and applies it to the reactive power optimization in actual regional power grid. Results show that the proposed mathematical model and algorithm are effective and practical.
