The inclusion of large numbers renewable energy sources (RESs) can lead to the operation electric-power systems close their natural stability limits. To improve stability, flexibility and fast control RESs be exploited. However, must “told” what do for sake “common good”. One possibility is apply global based on functions, but this requires appropriate mathematical tools models. In addition “re...

In this modern world, the electrical power consumption is vast and its power system is complex and faces many challenges due to growing demand and construction of new lines. Transient stability is one of the main system insecurity when large disturbances occur. Here at first conventional shunt facts devices Static VAR Compensator (SVC), Static Synchronous Compensator (STATCOM)are used as an add...

The Doubly Fed Induction Generator (DFIG) is getting wider popularity due to its ability to adapt with variable wind speed and to capture more wind energy. Though DFIG has a salient feature of the fault ride through capability, this is not sufficient to preserve the necessity of the grid code when the DFIG system is connected with the grid. To accomplish this goal, a DC resistive superconductin...

FACTS devices can help the damping of power system oscillations. The objective of this paper is to design and propose a systematic approach for damping controller to validate results by comparing with lab prototype. This paper presents a control scheme, comprehensive analysis and result obtained for the dynamic control of power transmission, damping of oscillations with Unified Power Flow Contr...

in this paper, a two-surfaces sliding mode controller (tssmc) is proposed for the voltage tracking control of a two input dc-dc converter in application of electric vehicles (evs). the imperialist competitive algorithm (ica) is used for tuning tssmc parameters. the proposed controller significantly improves the transient response and disturbance rejection of the two input converters while prese...

Stability is an important constraint in power system operation; the transient stability constrained optimal power flow (TSCOPF) has a considerable attention in recent years. The solution obtained from the conventional optimal power flow (OPF), which considers only the static constraints, does not guarantee transient stability in the system against possible contingencies such as line fault. In t...

Evaluation of Explicit Congestion Control for High-Speed Networks. (May 2007) Saurabh Jain, B.Tech., Indian Institute of Technology Roorkee Co–Chairs of Advisory Committee: Dr. Dmitri Loguinov Dr. A. L. N. Reddy Recently, there has been a significant surge of interest towards the design and development of a new global-scale communication network that can overcome the limitations of the current ...

A transient damping method (TDM), introducing the frequency of a virtual synchronous generator through high-pass filter (HPF) to power reference, is usually adopted stabilize system against disturbances. However, different from small-signal stability perspective, this letter reveals that gain H...
