With the increasing penetration of renewables in power system, secondary frequency regulation (SFR) is becoming a big challenge for conventional coal-fueled thermal generator units. To address this issue, a stricter AGC criteria to regulate the generators has been but forward. However, old-fashioned units can hardly meet the requirements and thus are subject to penalty. In this paper, an approach...
As total inertia of a power system decreases with an increase in wind penetration, it cannot fully recover the frequency following a load perturbation. Control performance standards (CPS) deteriorate due to an increased variability in Area Control Error (ACE). Throughout a day, the operating conditions in a power system changes. As, the fixed gain controllers are only designed for nominal operating...
