This paper investigates the large disturbance stability of single voltage source converter (VSC) connected to infinite bus system through transmission line. One conservative stable region is obtained via direct method Lyapunov. Based on Poincaré Theorem, it interesting find there might exist limit cycle between boundary and angle unstable equilibrium point (UEP). Accordingly, nonlinear damping ...

This paper presents the design of a non-linear controller to prevent an electric power system losing synchronism after a large sudden fault and to achieve good post fault voltage level. By Direct Feedback Linearization (DFL) technique robust non-linear excitation controller is designed which will achieve stability enhancement and voltage regulation of power system.

A Honey Bee Mating Optimization (HBMO) technique is proposed for the optimal tuning of the Power System Stabilizer (PSS) in this paper. The design problem of robustly selecting PSS parameters is formulated as an optimization problem according to the time domain-based objective function which is solved by the HBMO technique that has a strong ability to find the most optimistic results. To achiev...

An important issue related to power system stability is to properly damp low frequency oscillations. Traditionally, these oscillations have been damped by means of power system stabilizers. In recent years, FACTS devices equipped with a power oscillation damper have been also efficiently used for damping oscillations. This paper is a tutorial for designing such power oscillation damper. The pap...

An optimal procedure for designing coordinated output feedback damping controllers of power system stabilizer (PSS) and STATCOM is developed for achieving and enhancing dynamic stability in single-machine infinite-bus power system. The coordinated design problem of STATCOM and PSS with output feedback controllers over a wide range of loading conditions is formulated as an optimization problem w...

In this paper, a Non-dominated Sorting Genetic Algorithm-II (NSGA-II) based approach is presented for distribution system reconfiguration. In contrast to the conventional GA based methods, the proposed approach does not require weighting factors for conversion of multi-objective function into an equivalent single objective function. In order to illustrate the performance of the proposed method,...

The impact of wind energy generation connected to a weak grid is studied with SIMULINK as simulation platform. The wind energy conversion system is modelled by a squirrel cage asynchronous induction machine (ASM). The grid is modelled as an infinite bus. In the proposed system the ASM is connected to the grid through a DC-link with incorporated battery storage. An ultracapacitor (UCap) bank in ...
