Reactive Power Optimization Strategy Considering Electricity Market Environment for Wind Farm

In power market environment, reasonable consideration of reactive power generation cost is conducive to mobilizing the enthusiasm of power suppliers to participate in voltage regulation in power system. First, the reactive power zone offer model in power market environment is established. Then, aiming at the wind farm composed of permanent magnet direct-drive wind turbines, a reactive power optimization strategy with the objective function of minimizing network loss, voltage deviation and reactive power cost is proposed. This strategy can effectively reduce the generation cost and can improve the voltage stability of the power system. Finally, taking IEEE 14 bus as an example, the corresponding simulation model is established in GAMS simulation software, and the MINLP solver is used to solve the problem. The simulation results can verify the rationality and effectiveness of the optimization model.
