“…Load flow studies were carried out in PSAT toolbox and it is found that bus 8 is the weakest and the voltage is below 0.95 per unit. So reactive power support in form of STATCOM is applied at bus 8 and it alleviates the voltage to 1.036-0.94828 per unit significant voltage regulation is observed in area 2 (Padhy et al , 2012; Ganesh et al , 2014a, b).…”

“…To alleviate the voltage instability STATCOM has to be installed in area 2. Since bus 5 connects areas 1 and 2, while one of the tie line is at bus 4, connecting areas 1-3, which also needs voltage support hence STATCOM is installed at bus 4 to provide necessary reactive power support (Ganesh et al , 2014a, b).…”

“…For two area system the eigenvalue analysis of the system shows that there are two modes of oscillations oscillating at different frequency and the participation of the generator speed deviations (Δω2, Δω3, Δω4) in the these oscillating modes is also shown in Table I. Mode I, that is, system oscillating at frequency of 0.64 Hz has poor damping in comparison to the other mode (Ganesh et al , 2014a, b).…”

“…Use of non-linear control techniques such as fuzzy logic control and artificial neural network (ANN) have been used in designing supplementary controller for STATCOM to damp the inter-area oscillations (Mohagheghi et al , 2005, 2007, 2008; Chandrakar and Kothari, 2007; Ray et al , 2008; Harikrishna et al , 2011; Dhal and Rajan, 2012; Ganesh et al , 2014a, b). The effectiveness of the fuzzy interface system depends upon the selection of the membership function.…”

Purpose The purpose of this paper is to develop an adaptive fuzzy controller for STATCOM to damp low-frequency inter-area oscillation over wide operating range using wide area signals in multimachine power system. Design/methodology/approach In this paper tuneable fuzzy model is proposed where the parameters of the fuzzy inference system are tuned by using the adaptive characteristic of the artificial neural network. Based on back propagation algorithm and method of least square estimation, the fuzzy inference rule base is tweaked according to the data from which they are modelled. The wide area control signals, for the proposed controller, available in the power system are selected on the basis of eigenvalue sensitivity defined in terms of participation factor. Findings The effectiveness of the proposed controller with wide area signals is tested on two test cases, namely, two area network and IEEE 12 bus benchmark system. The comparative analysis of the proposed adaptive fuzzy controller is carried out with conventional STATCOM controller along with fuzzy-and neural-based supplementary controller all using selected wide area signals. The results show that neural network tuned fuzzy controller leads to better system identification and have enhanced damping characteristics over wide operating range. Originality/value In the available literature, numerous researchers have indicated the use of fuzzy logic controller and neural controller along with their hybrid schemes as STATCOM controller for improving the dynamics of the multimachine power system using local signals. The main contribution of the paper is in using the hybrid intelligent control scheme for STATCOM using wide area signals. The advantage of proposed scheme is that the performance of well-designed fuzzy system can be enhanced with the same training data that are used for designing a neural controller thus giving enhanced performance in comparison to individual intelligent control scheme.

“…The method uses the frequencies of the generators as the feedback data for the control system. In [36] a fuzzy damping control design for damping swing mode using a STATCOM and global stabilizing signals is presented. The proposed controller for the STATCOM effectively enhances the angular stability of the multimachine network.…”

Wide area monitoring systems (WAMS) together with phasor measurement units (PMUs) are the key to implement wide area control systems (WACS). WACS are responsible of achieving different control objectives from signals and measurements taken of a wide area network. Control objectives can be focused on a large region of the network or part of it. Furthermore, flexible ac transmission systems (FACTS) are devices that allow to implement the control laws designed and developed from measurements of WAMS/PMU. This paper presents a review of the current state of the art of WACS incorporating FACTS devices, specifically, the different FACTS configurations, applications and control used.Index Terms-Wide area control systems, wide area monitoring systems, flexible ac transmission systems, power system control, phasor measurement unit.
