6 FAQs about [PQ control of microgrid inverter]

Can intelligent p-q control be used in a microgrid?

Encouraged by the aforementioned analysis, a novel intelligent P-Q control method is proposed for three-phase grid-connected inverters in a microgrid by using an adaptive population-based extremal optimization (APEO).

How a grid-connected inverter is designed in a microgrid?

The inverter is designed from a universal bridge. Since we are using the topologies of directly connected inverter to PV cell thus, we use the grid-connected inverter's P-Q control strategy in the microgrid [11 – 14]. In the inverter's P-Q control, the inverter's grid output current and output current are compared.
