“…The effectiveness of this idea for the improvement of the stability performance of power systems has been proved in [5]. Superconducting magnetic energy storage (SMES) represents a promising FACTS technique and has become a significantly effective tool since it is capable of injecting and absorbing the active and reactive power rapidly [6][7][8][9]. A lot of attention has been paid to the application of SMES.…”

This article studies the H ∞ control problem for single-machine infinite bus power systems with superconducting magnetic energy storage (SMES) via simultaneous design of generator excitation control and SMES control. In the control system design, the exciter dynamics and unknown external disturbances are considered for practical implementation in power systems. A new synthesis framework is proposed to address the robust control problem of power systems with SMES. First, from the energy perspective, the interconnection and damping assignment (IDA) approach is applied to improve the transient performance of power systems. Second, by introducing the idea of virtual control in the design process, the authors obtain the solution of a partial differential equation that is a crucial point and cannot be obtained by using the traditional IDA method. Third, in order to enhance the robustness of the closedloop system, the authors study the H ∞ control design that is challenging and difficult for power systems considering the above mentioned practical considerations. In addition, the authors use a novel equivalent generator model to avoid using unmeasurable infinite bus voltage. Simulation results also show the effectiveness and advantage of the proposed controller.

“…These solutions are such as using wide-area measurement signals [3], phasor measurement unit [4] and flexible AC transmission system etc. In these solutions, one of the powerful methods for enhancing the transient stability is to use flexible AC transmission sys-Transient Stability Assessment of Two-Area Power System with LQR based CSC-STATCOM S.

Even though the prime objective of shunt FACTS devices (SVC, STATCOM) is to maintain bus voltage by absorbing (or injecting) reactive power, they are also competent of improving the system transient stability by diminishing (or increasing) the capability of power transfer when the machine angle decreases (increases), which is accomplished by operating the shunt FACTS devices in inductive (capacitive) mode.…”

Original scientific paper A current source converter (CSC) based static synchronous compensator (STATCOM) is a shunt flexible AC transmission system (FACTS) device, which has a vital role as a stability support for small and large transient instability in an interconnected power network. A robust linear quadratic regulator (LQR) based controller for CSC-STATCOM is proposed. In this paper, LQR based CSC-STATCOM is designed to enhance the transient stability of two-area two-machine power system. First of all, modeling & LQR based controller design for CSC-STATCOM are described. After that, the impact of the proposed scheme on the test system with different disturbances is demonstrated. The feasibility of the proposed scheme is demonstrated through simulation in MATLAB and the simulation results show an improvement in the transient stability of power system with CSC-STATCOM. Also, the robustness and effectiveness of CSC-STATCOM are better rather than other shunt FACTS devices (SVC & VSC-STATCOM) in this paper.

“…In (wang et.al. 2002) and (Tan & wang, 2004), the robust non-linear control based on a direct feedback linearization technique has been applied to design an excitation system, a thyristor controlled series capacitor (TCSC) and a SMES. However, the drawback of this design method is a tuning of Q and R matrices for solving Riccati equation by trial and error.…”
