Abstract
New questions related to the quality of the grid energy and reliability with the insertion of distributed energy resource (DER)s, and, new problems may arise as voltage variations by load variations and the determination of current limits. Thus, the control of the DER units should be cooperative and active to support the voltage regulation, as the frequency is still controlled from the main grid. Most of control strategies applied for distributed generation systems (DGS) have relied on power controls based on active (P) and reactive reactive (Q) power droop to achieve. This paper shows a comparative study between the classic PQ droop control and a accurate IV droop control.
