“…These include poleplacement, 11 partial pole-placement, 12 eigen-structure assignment, [13][14][15] phase compensation, 16,17 and phase shaping. 18 The pole-placement is a straightforward method with an advantage of assignment of the closed-loop poles, however, leading to complex models and, therefore, the difficulty in designing complex controllers arises. 19 Furthermore, many classical methods prevalent in the literature [20][21][22][23][24] require reduction of the system model before designing the controllers.…”

Summary For improvement of the operation and control of the power system, the flexible AC transmission system devices are significantly used. This paper proposes a model‐based frequency response matching technique for designing a lead‐lag power system stabilizer and a thyristor controlled series capacitor controller to improve the small signal stability. The method relies on development of an appropriate reference model, based on the desired specifications that can be attainable by the system dynamics. The unknown controller parameters are obtained by the frequency response matching between the closed‐loop control system and the reference model. The efficacy of the proposed controllers is examined on an unstable test power system taken from the literature. Improvement of the damping factor and the other performance indices shows robustness and effectiveness of the proposed controllers for stabilizing the power system oscillations in comparison with some design methods prevalent in the literature. It is illustrated through rigorous simulation that the proposed controller works successfully for stabilizing the power system over a wide unstable operating conditions and perturbed system models.

“…Robust design of PSSs is to achieve desired performance over multiple operating modes. Many robust design methods have been reported such as eigenstructure assignment [4], P-vr method [5,6], computational technique [7], and search-based method [8][9][10]. Coordinated design of PSSs is to coordinate the parameters of different PSSs in multimachine power systems so that the overall system's stability is improved.…”

“…In the mathematical model of electrical turbine generators connected to an electrical system, it is not always possible to determine exactly all the parameters. Moreover, because of simplification and linearization of models there is the so-called unmodeled dynamics [11,12]. This leads to the fact that the system stabilizers that are synthesized for one set of model parameters do not always provide the desired level of stability and quality control for other parameters values within the permissible limits.…”

Introduction. This research aims to develop the method of synthesis of interconnected robust power system stabilizer (IRPSS) for power supply systems of sugar factories with own turbine generators. Materials and methods. The mathematical tools of H ∞ synthesis with pole placement and the linear matrix inequalities (LMI) are used for developing the method of IRPSS synthesis. MATLAB Simulink is used to verify synthesized regulator by computer simulation. Results and discussion. A model of power supply system with own generator, automatic exciter regulator, turbine and speed governor is constructed. The controlled object nonlinear differential equations model is linearized and simplified by reducing of its order using Schur's method. The model is extended with chosen weighting functions preparing for H ∞ synthesis procedure. The LMI region is chosen in the form of a conic sector for satisfying condition of lower oscillability of transient process, which is the main goal of such a regulator to optimize turbine generator operation process. The IRPSS for extended model was synthesized, using H ∞ synthesis procedure with poles placement. The regulator is presented in the form of matrix continuous transfer function. The transition process of 3-phase short-circuit fault behind the transformer and subsequent automatic re-closing is simulated with full-order nonlinear model with IRPSS and compared with standard system stabilizer and the system without stabilizer. The graphs of modelled transients demonstrate effectiveness of IRPSS. Conclusion. The developed method can be used for operation process optimization of turbine generators in sugar factories. The synthesized IRPSS was found to have satisfying robust stability and performance qualities for given structure of power system.
