abstract
The increasing number of distributed generation units has led to the development of microgrids, to which the distributed generators are commonly interfaced by means of a voltage-source inverter (VSI). When the microgrid is operating independently of the power system, i.e., in islanded mode, two levels of control can be distinguished for these VSIs: power control and voltage control (frequency and amplitude). The set-point values for the voltage controller are obtained from the power controller. This paper investigates theoretically and experimentally the benefits of using several PID control structures for the voltage control. Theoretical insights into the dynamics of such a system emphasize the benefits of measuring current signals for control purposes and adding voltage measurements to the output of the controllers. Direct voltage control and cascade voltage control are compared both with and without forward compensation of the grid voltage. Simulation and experimental results are given showing that such PID-type controllers on a digital signal processor are simple yet effective strategies for an accurate voltage control in islanded microgrids.
