This paper presents the development of a PQ-control model for the grid connected single-phase and three-phase .
The voltage and frequency reference of the microgrid is also set by the main grid. Therefore the main task of a DG unit is to control the output real power (P) and reactive power (Q) [68], [69]. The P, Q generated by a DG can be controlled either by current-based or by voltage-based power flow control [70]. 7.2.
Whether a microgrid operates in grid-connected or islanded mode, active and reactive power (PQ) control is a basic control mode for IBRs [10]. The controllers at the secondary and tertiary levels generate PQ reference values and supplementary signals for the primary controllers [11].
This comprehensive review paper offers an overview of PQ issues in microgrids, covering various types of PQ disturbances, their key features, and the most relevant PQ standards. Additionally, it provides an extensive case study review of published research on PQ analysis of microgrid and renewable energy based systems.
In microgrid systems, a control called PQ control strategy is also used in the primary control layer. In this strategy, the controller controls the system voltage by controlling active and reactive power injected into the system by the inverters used as the grid interface of DG and storage units.
