“…A pole assignment and LQR-based state feedback controlled SVC is presented by Zhou for studying transient and steady-state performances [47]. A periodic output feedback based STATCOM damping controller design is proposed by Pant et al [48]. The presented controller effectively damps out the oscillations without any PSS in the system.…”

A comprehensive review on stability analysis in multimachine power system is presented in this study. The increasing demand of power has led to the expansion of power system and complexity in design as well as operation. This threatens to deteriorate the stability and reliability in the power network. However, with the advances in semiconductor and power electronic control technology, various flexible AC transmission systems (FACTS) are designed to enhance the power system stability. Different power system configurations with the incorporation of conventional and distributed generations (DGs) are proposed whose stability is being tested in the presence of the FACTS controllers. The optimal damping of power system oscillations under transient operating conditions are studied in presence of HVAC and HVDC links with conventional as well as DG systems and energy storage options like battery, supercapacitors and so on. Different control approaches such as classical control, robust control, wide-area control along with soft computing approaches like neural networks, fuzzy logic control, adaptive neurofuzzy inference system, genetic algorithm, particle swarm optimisation and so on are broadly discussed. A comparative analysis of different methodologies is presented to establish a quick survey of the proposed solutions for stability enhancement.

“…14 Based on direct linearization method, two damping controllers for STATCOM have been designed. 15,16 In spite of these developments, to the best of the authors' knowledge, there is very few works on coordinated control of the AVR and STATCOM. 17 It is well known that the motivation of linearization is to obtain a feedback equivalent linear system by canceling the internal nonlinearities of the considered systems.…”

“…18 One of the advantages of Hamiltonian function is that Hamiltonian function method can effectively use the internal structural characteristics during the controller design, and hence, it has attracted great attention in nonlinear system synthesis and has obtained many achievements in the power system stabilization and performance enhancement. 2,16,18 The STATCOM is regarded as a reactive current source, and the controllers of STATCOM have been designed. 2,3 To the best of our knowledge, controllers of STATCOM have not been designed using pseudo-generalized Hamiltonian function theory.…”

Flexible alternating current transmission system devices are widely used to enhance the power transfer limit and stability improvement in transmission networks. They also help damp out both local and inter-area low-frequency oscillations. Using pseudo-generalized Hamiltonian theory, this article investigates the coordinated control of automatic voltage regulator of synchronous generator and static synchronous compensator in multi-machine power systems. First, via a proper variable transformation and pre-feedback control, the dissipative pseudo-generalized Hamiltonian realization of the static synchronous compensator and power system are completed, respectively. Then, based on the obtained dissipative pseudo-generalized Hamiltonian realization, a brand new nonlinear coordinated control law is constructed. Simulation results indicate that the proposed coordinated control scheme can effectively improve both the transient stability and voltage regulation performance of the power system.
