Abstract
This paper presents a novel method for determination of location and tuning of parameters of electronic static synchronous compensator (E-STATCOM) for oscillation control in Wide area monitored power systems. The effect of active and reactive power injection by E-STATCOM, on the damping performance of a two-area interconnected system has been studied and analyzed. Dynamic non-linear simulations of the test system with appropriate modeling were carried out for evaluation of performance of the proposed controller design, and to take forward the previous works done on wide area control of power systems. Novel attempt has been made for optimal selection of nodes for positioning E-STATCOMs in multi-machine power system, by considering the participation factor of angular variation of voltage vector in modal analysis. Many operating conditions have been considered for the proposed study under both normal states and contingencies. Results of the simulation indicate that the proposed method is highly effective in suppressing the low frequency oscillations of the targeted modes and performs better than the flexible alternating current transmission system devices without the support of energy storage. This method is also used for cloud application.
