Reactive power compensation in distributed networks with wind turbine integration using resonant corrector

In this paper, the control of a Distribution Static Synchronous Compensator (DSTATCOM) based on Resonant Corrector (RC) is proposed, for the reactive power compensation of a distribution network with wind turbine (WT) integration. The sinusoidal system transformation to the dq0 reference frame is usually made, in order to model Proportional + Integral (PI) controllers. However, these controllers are unable to completely remove voltage unbalance transients during the power interchange between the distribution network and the WT. The use of a Resonant Corrector (RC) for compensating voltage disturbances allows developing the control in the abc reference frame; thus, it is not necessary the use of a Phase Lock Loop (PLL) and the system with the minimum of components is managed, generating a sensorless control, working reliably in steady state and under unbalanced transient operation conditions. The distribution network through MATLAB & Simulink® is simulated.
