Power system stabilizer (PSS) is one of the most important controllers in modern power systems for damping low frequency oscillations. Many efforts have been dedicated to design the tuning methodologies and allocation techniques to obtain optimal damping behaviors of the system. Traditionally, it is tuned mostly for local damping performance, however, in order to obtain a globally optimal perfo...

Modern computing substrates like cloud computing clusters, massively multi-core processors, and generalpurpose GPUs offer a wealth of computing power with the caveat that programmers must carefully structure their programs to fit within various hardware and communication limits in order to get high performance. Unfortunately, modern abstractions expressly hide machine structure from the program...

The interline power flow controller (IPFC) is a concept of the FACTS controller for series compensation which can inject a voltage with controllable magnitude and phase angle among multi lines. This paper proposes a novel IPFC-Based Damping Neuro-control scheme using PSO for damping oscil‌la‌t‌i‌o‌ns in a power system to improve power system stability. The add‌i‌tion of a supplementary controll...

This paper proposes the application of a hierarchical fuzzy system (HFS) based on multi-input power system stabilizer (MPSS) and also Static Var Compensator (SVC) in multi-machine environment.The number of rules grows exponentially with the number of variables in a conventional fuzzy logic system. The proposed HFS method is developed to solve this problem. To reduce the number of rules the HFS ...

In this paper, using a personal computer (PC), the practical implementation of scalar and vector control methods on a three–phase rotor surface- type permanent magnet synchronous machine drive is discussed. Based on the machine dynamic equations and the above control strategies, two block diagrams are presented first for closed-loop speed controlling of the machine drive/system. Then, the desig...

This paper proposes the application of a hierarchical fuzzy system (HFS) based on multi-input power system stabilizer (MPSS) in multi-machine environment. The number of rules increases exponentially with the number of variables in a standard fuzzy system. This problem is solved in the proposed HFS method. In this method, the total number of rules increases only linearly with the number of input...

This paper presents results about power system stabilizers (PSS) coordination in multi-machine power systems. Due to their versatility, power system stabilizers have been employed extensively to enhance the power oscillations damping. One of the main tasks within this context is to estimate the best PSS’s parameters. In this paper, this is solved by a neural network. The applicability of the pr...

This paper presents a systematic procedure for designing a wide-area centralized Continuous Time Model Predictive Controller (CTMPC) to improve the angular stability of a multi-machine power system. In this scheme, each generator is assumed to be provided with a local controller to damp out the local mode of oscillations and also employs a global signal from the centralized controller to damp o...
