Minimal overshoot V-F control for islanded microgrids

Islanded microgrids' dynamics are greatly affected by the controllers' gains and power-sharing parameters. This paper considers an islanded microgrid containing two distributed generation (DG) units. Each DG has its pulse width modulated (PWM) inverter for three phases. Each inverter has two control loops in cascade. The inner loop is a current loop and the outer loop is a voltage loop. The controller of each loop is designed to provide good …
