Abstract
This article emphasizes on a modified static series synchronous compensator (mSSSC) in transmission lines for enhancing the dynamic stability of Automatic Generation Control of a double area Distributed Generation source integrated Thermal-Thermal interconnected multi source power network. A practical insight is provided incorporating 3%/min generation rate constraint and 0.0036 Hz governor dead band to each unit in each area. Proportional-Integral-Derivative Controller Incorporating first order filter effect is used as a secondary controller to reduce the area control error. Impact of Static Series Synchronous Compensator (SSSC) and then SSSC with Lead Lag Compensator is evaluated with 1% and 1.5% disturbance respectively in Area 1 and improvement of dynamic stability is executed in terms of reduced crest undershoot, crest overshoot and settling time. A modified compensator of SSSC by employing optimum time constants of Lead Lag SSSC is utilized in the tie-line to further improve the system dynamics by reduced settling time.
