Active power limiter for grid connection of modern renewable SSG SPC

Management of Renewable Static Synchronous Generation units based on Synchronous Power Controller (RSSG-SPC), not only provides grid synchronization without using PLL and gives proper dynamic to output active power, moreover yields simple solution to overcome technical constraints on these units. Control of active power level injected to the grid is one of these key constraints which can overcome by an Active Power Limiter (APL). In this work, an APL designed based on the classic power equation is proposed for this kind of modern RSSG-SPCs. Primary Simulink analysis and real time test results confirm that suggested APL can control and limit both maximum and minimum level of output active power for several grid connection cases.Peer ReviewedPostprint (published version
