“…PI controllers are conventionally employed for both the tasks while attempting to decouple the d-and q-axiscurrent regulators. In this study, the strategy adopted in [17] for shunt current control has been taken.The inverter current (i p ) is split into real (in phase with acbus voltage) and reactive components. The reference value for the real current is decided so that the capacitor voltage is regulated by power balance.…”

“…As per the strategy, the original currents in d-q frame (i pd ,i pq ) are now transformed into another frame,d"-q" frame, where d"-axis coincides with the ac-bus voltage (V s ), as shown in Thus, in (d"-q") frame, the currentsi pd" andi pq" represent the real and reactive currents and they are given by : (10) (11) Now, for current control, the same procedure as outlined in [17] has been adopted by re-expressing the above differential equations as: (12) (13)…”

An Unified Power Flow Controller (UPFC) is a typical Flexible AC Transmission System (FACTS) device playing a vital role as a stability aid for large transient disturbances in an interconnected power system.This paper deals with the design of Feedback Linearising Controller (FBLC) for UPFC.The disturbances are created in the SMIB system and the results are simulated.The results proved the supremacy of the Power System Stabilizer (PSS) equipped with FBLC over the PSS equipped with Proportional Integral(PI) controller.

Abstract-The unified power flow controller (UPFC) is a pair of back to back power electronic inverters which controls the real and reactive power flow in a transmission line. This paper describes the modeling and simulation of IEEE 30 bus system employing UPFC. Simulink models are developed for IEEE 30 bus system with and without UPFC. Digital simulation using MATLAB/SIMULINK is done with these models and the results are presented. The effect of UPFC on real power, reactive power and the voltage is also presented.

“…In conventional control scheme, there are two voltage regulators designed for these purposes: ac voltage regulator for bus voltage control and dc voltage regulator for capacitor voltage control. In the simplest strategy, both the voltage regulators are proportionalintegral (PI) type cascaded controllers [6,7]. The modeling and control design is usually carried out in the synchronous d Á/q frame, as it is quite standard [8].…”

This paper investigates application of a multivariable control technique to the multi-input multi-output (MIMO) nonlinear model of a static synchronous compensator (STATCOM). The proposed controller design is based on a feedback linearization scheme. Its prime goal is the coordinated control of ac and dc voltage for a STATCOM installed in a power distribution system. First, the nonlinear mathematical model of STATCOM along with the distribution system is derived. Then, by using input Á/output feedback linearization, a state feedback control law is obtained by pole placement. The efficacy of the control strategy is evaluated by digital computer simulations on the complete system for various types of loads and/or disturbances. The comparative study of these results with those obtained in a conventional cascade control architecture establishes the elegance of this new control scheme. #
