Title
Simultaneous Regulation Of Active And Reactive Output Power Of Parallel-Connected Virtual Oscillator Controlled Inverters
Abstract
A control strategy is presented that simultaneously regulates both the active and reactive power of two parallel-connected virtual oscillator controlled inverters. In microgrids with distributed generation sources, it is of vital importance to regulate the output power of each source independently. This facilitates better energy source utilization, reduced losses and stress on the distribution lines. PI controllers are proposed that are used to tune the current and voltage gains of the virtual oscillator controller to regulate the inverter output power. Control laws are presented to determine the values for current and voltage gains to achieve both the active and reactive output power set-points simultaneously. Further, a security constraint is derived that guarantees the existence of real-valued solutions for current and voltage gains corresponding to the desired output power set-points. The main advantage associated with this security constraint is the confidence that a particular output power set-point can be achieved. Simulation results show that the VOC inverter with the proposed control strategy follows the desired reference power set-points effectively.
