Satisfactory damping of power oscillations is an important issue to be addressed when dealing with the angle stability of power systems. This phenomenon is well-known and observable especially when a fault occurs. To improve the damping of oscillations in power systems, supplementary control laws can be applied to existing devices. These supplementary actions are referred to as power oscillatio...

In this paper an attempt has been made to study the application of Thyristor Controlled Series Capacitor (TCSC) to mitigate small signal stability problem in addition to congestion management of a heavily loaded line in a multimachine power system. The Flexible AC Transmission System (FACTS) devices such as TCSC can be used to control the power flows in the network and can help in improvement o...

Saluran transmisi yang berfungsi menyalurkan energi dari pusat pembangkit ke beban harus secara efisien. Akan tetapi, jaringan luas memungkinkan pengoperasian saluran menjadi tidak Hal ini terjadinya rugi-rugi daya dan drop tegangan pada sistem. Oleh karena itu, dibutuhkan upaya untuk memanfaatkan kapasitas sistem tersedia efektif, salah satunya dengan memasang perangkat baru seperti TCSC (Thyr...

The paper presents the design of linear robust decentralised fixed-structure power system damping controllers using genetic algorithms (GA). The designed controllers follow a classical structure consisting of a gain, a wash-out stage and two lead-lag stages. To each controller is associated a set of three parameters representing the controller gain and the controller phase characteristics. The ...

A method for the design of supplementary damping control system for TCSC in a power system is presented in this paper. The problem is formulated as an optimization problem with an eigenvalue based multi-objective function. Various optimization techniques have been used in the past but here, a novel random walk optimization technique is used to find optimal set of controller parameters by minimi...

Rapid industrial development and innovations in technology bring about the menace of congestion deregulated power systems (DPS). The transmission lines are continuously working under a stressed condition with reduced transfer capacity. In this situation, losses voltage deviations at load buses increased hence reduce system stability. To mitigate congestion, improving available capability (ATC) ...

In this paper we present the basic principles of supervised learning and reinforcement learning as two complementary frameworks to design control laws or decision policies within the context of power system control. We also review recent developments in the realm of automatic learning methods and discuss their applicability to power system decision and control problems. Simulation results illus...
