“…A comparison of the dynamic response curves in Fig. 10 reveals that the load bus voltage returned to the preset values of 0.986 pu following the disturbance for the STATCOM with the function of the proposed controller (EA + SDC), EA and LOC [16], respectively. It is noted that, with the proposed controller, the STATCOM reactive current (i qe ) settled towards to inductive region rapidly in a well-damped sense as compared with EA and LOC when the wind farm subjected to step load change disturbance.…”

This study presents a new control design approach for the wind farm voltage regulation using static synchronous compensator (STATCOM). A mode decoupling proportional plus integral (PI) controller, in which the control gains are synthesised by eigenstructure assignment (EA), is proposed for the STATCOM. EA is a state-space approach, which is used to improve system damping by eigenvalue assignment and alter system mode shape by eigenvector assignment. To embed the physical PI control loops in the state-space model, an equivalent transformation is proposed to map the feedback gain matrix to the PI controller. Owing to the presence of the physical PI control loops, the control signals would not mire into saturation when appropriate limiter according to the STATCOM capacity is placed in the control variables. To further alleviate the undesired oscillation mode excited by transient disturbance, a lead-lag-based supplementary damping controller (SDC) is adopted. Simulation comparisons are provided to show that the proposed technique can be an effective method for mitigating the voltage fluctuation in the wind farm because of the load changes and the wind gust.

“…This is best accomplished by regulating the PWM switching commands to alter the modulation index and phase angle in Equation [7.5]. Since its inception, a variety of control approaches have been proposed for STATCOM dynamic control (Schauder and Mehta, 1993;Lehn and Iravani, 1998;Rao et al ., 2000;Sahoo et al ., 2002;Wang et al ., 2002;Liu et al ., 2003;Dong et al ., 2004;Soto and Pena, 2004;El-Moursi and Sharaf, 2005;Cheng et al ., 2006;Jain et al ., 2006;Lu and Ooi, 2007;Mohagheghi et al ., 2007;Saeedifard et al ., 2007;Song et al ., 2007Song et al ., , 2009Sternberger and Jovcic, 2009;Hatano and Ise, 2010;Liu and Hsu, 2010;Spitsa et al ., 2010;Wang and Crow, 2011). The majority of approaches involve traditional linear control techniques, in which the nonlinear equations of the VSC average value model are linearized at a specifi c equilibrium (Schauder and Mehta, 1993;Lehn and Iravani, 1998;Rao et al ., 2000;Liu et al ., 2003;Dong et al ., 2004;El-Moursi and Sharaf, 2005;Cheng et al ., 2006;Saeedifard et al ., 2007;Sternberger and Jovcic, 2009;Hatano and Ise, 2010).…”

“…To compensate for a change of operating conditions, a variety of controls have been reported that provide satisfactory performance over a wide range of operating conditions (Sahoo et al ., 2002;Liu et al ., 2003;Soto and Pena, 2004;Lu and Ooi, 2007;Song et al ., 2007Song et al ., , 2009Spitsa et al ., 2010;Wang and Crow, 2011). One approach is to adaptively change the gains of the PI controller in response to changes in operating condition.…”

“…Thus, a number of intelligent methods have been proposed, the PI controller advances similar to particle swarm optimization [11], neural networks [12], and artificial immunity [13]. In literature [14], [15], adaptive control and linear booming clout have been reported for their anti-external disturbance ability. In literature [16]- [17], a popular dead-beat current controller is used.…”

STATCOM is one of the shunt type FACTS controllers which can supply reactive power and improve bus voltage. STATCOM, a controlling device used on alternating current transmission networks, has advantages like transient free switching and smooth variation of reactive power. This paper proposes a cascaded multilevel inverter type DSTATCOM and DVR to compensate voltage sag in utilities in power distribution network. The proposed DSTATCOM is implemented using multilevel topology with isolated dc energy storage and reduced number of switches. A DVR injects a voltage in series with the system voltage and a D-STATCOM implant a current into the system to correct the voltage sag, swell and interruption. The phase shifter PWM technique is described to generate firing pulse to cascaded inverter. The proposed neuro-fuzzy controller follow itself to the sag and provides effective means of mitigation .The voltage sag with the minimum harmonic at the efficacy end. The proposed technique is simulated using MATLAB/Simulink.
