This paper presents three new systematic approaches for computing coefficient matrices of the Heffron-Phillips multi-machine model (K1, …, K6). The amount of computations needed for conventional and three new approaches are compared by counting number of multiplications and divisions. The advantages of new approaches are: (1) their computation burdens are less than 73 percent of that of convent...

Static Synchronous Series Compensator (SSSC) is a series compensating Flexible AC Transmission System (FACTS) controller for maintaining to the power flow control on a transmission line by injecting a voltage in quadrature with the line current and in series mode with the line. In this work, an Adaptive Network-based Fuzzy Inference System controller (ANFISC) has been proposed for controlling o...

In order to test and verify the phenomena of power system voltage collapse, this article chooses a single-load infinite-bus single-machine as sample systems based on PS-5G carry out stability physical tests, an induction motor adjustable resistor are used constitute comprehensive load. The results show that in system, with decrease resistance gradually, load active is gradually increasing bus d...

This paper employs a probabilistic collocation method (PCM) to quantify the uncertainties in dynamic simulations of power systems. The approach was tested on a single machine infinite bus system and the over 15,000 -bus Western Electricity Coordinating Council (WECC) system in western North America. Compared to the classic Monte Carlo (MC) method, the PCM applies the Smolyak algorithm to reduce...

The steady-state stability limit and the system positive damping can be improved by conventional Power System Stabilizer (PSS). However, in order to have abilities such as the online tuning and optimal real-time damping in the entire operating range, robust design of PSS in required. A novel robust PSS design using Artificial Neural Network (ANN) and Imperialist Competitive Algorithm (ICA) for ...

This paper deals with the design of both single input and dual input conventional PSS which is used to damp the low frequency rotor oscillations taking place in power systems. The single input PSS used here are power based derivative type and speed based lead-lag type stabilizer, the dual input stabilizer, PSS3B has two inputs namely from change in speed and deviation of electrical power and ha...

This paper offers novel non-linear control of a doubly fed induction generator (DFIG) and unified power flow controller (UPFC) for transient stability increment with energy function (TEF) sliding mode observer in system. First, the TEF technique is considered damping system synchronous (SG), DFIG, UPFC, then time-derivative signals are estimated by second-order observer. The importance issue em...

This paper presents the comparison of applying an adaptive fuzzy controller with and without a variable structure controller (VSC) for a synchronous machine. A simplified linear model of the synchronous machine connected to an infinite bus with constant impedance is used. The multivariable system was previously decoupled to make easier the application of the control schemes. To control the syst...

Pelepasan beban secara tiba-tiba seperti saat terjadi hubung singkat dapat menghasilkan osilasi pada sistem tenaga listrik. Oleh karena itu, diperlukan suatu peralatan untuk mempercepat redaman tersebut. Salah satunya adalah dengan menggunakan PSS. Dalam melakukan pengaturan parameter dari PSS tersebut,diperlukan metode sehingga beroperasi optimal dalam menstabilkan sistem. penelitian ini, Part...
