4 FAQs about Dynamic phase locking of microgrid

What is a microgrid control strategy?

The proposed control strategy is based on the use of a phase locked loop to measure the microgrid frequency at the inverter terminals, and to facilitate regulation of the in-verter phase relative to the microgrid. This control strategy allows microgrids to seamlessly transition between grid-connected and autonomous operation, and vice versa.

What is a phase regulated in a microgrid?

The phase of the inverter voltage is regulated to control the active power output of the inverter. The basic idea behind this strategy is proposed in . The inverter interface with the microgrid can be modeled according to Vt t is the voltage on the grid side of the filter, and jX is the effective impedance between those two points.

How does a con-Troller control a microgrid?

To accomplish that goal, the proposed con-troller uses droop characteristics for active-power/frequency and reactive-power/voltage. The proposed control strategy is based on the use of a phase locked loop to measure the microgrid frequency at the inverter terminals, and to facilitate regulation of the in-verter phase relative to the microgrid.

Can a phase-locked loop be used for phase synchronization?

By using either an analog or a digital phase-locked loop (PLL), realization of phase synchronization is possible. The PLL may be unsatisfactory because of corrupted input signal with strong disturbances. To overcome such difficulties, synchronization method based on a multirate PLL can be used.
