This work develops a combined control for a stand‐alone permanent magnet synchronous generator (PMSG) working with variable source and output demand. The power circuit consists of one PMSG, driven by uncontrolled prime mover supplying load through two voltage source converter (VSC) connected through a dc link capacitor. The main objective of the control is to supply load at constant voltage and frequency, even with variation in source speed and power, and also to accommodate the change in load transients. The generator side converter control is developed in rotor flux oriented synchronously rotating reference frame, to keep the dc link voltage, of the back to back VSC, constant. The load side converter control is also developed in the synchronously rotating reference frame to supply load at constant voltage and frequency. The developed combined control strategy is implemented in MATLAB/SIMULINK environment and found to be successful under all considered operating conditions. The theoretical findings are experimentally verified with a real‐time prototype.
