Research on Optimal Method of Reactive Voltage Control for UHV Power Network
Reactive voltage fluctuation will affect the operational stability and safety of UHV power grid,but the optimization effect of the current reactive voltage control optimization method is not ideal in practice,not only the active power loss of the power grid is relatively high,but also the voltage exceeds the limit is relatively large.Therefore,the optimization method of reactive voltage control of UHV power grid is proposed.With minimum reactive power exchange and minimum active power loss as objectives,multiple objective functions were established,binding conditions were set,and the reactive power network control model was established.Particle swarm optimization was used to optimize the model,and the reactive power and voltage control optimization of UHV network was realized.The experimental results show that the active power loss and voltage overstep can be effectively reduced under the application of the design method,and the optimization effect is good.
