This paper presents a neural network based decentralized excitation controller design for large-scale power systems. The proposed controller design considers not only the dynamics of generators but also the algebraic constraints of the power flow equations. The control signals are calculated using only local signals. The transient stability and the coordination of the subsystem control activiti...

The demand of electricity globally led to the concept renewable energy resources for power generation that are eco-friendly and freely available from nature. solar photovoltaic systems wind-based generators considered as primary called Distributed Generation units they scattered in These operated with bidirectional converters by providing auxiliary services at grid side load either mode microgr...

Airborne wind energy (AWE) systems with electrical machine on the ground are a promising alternative to classical wind turbines. Such systems are operated in pumping mode with the reel-out phase generating electrical power and the reel-in phase dissipating power [1]. We discuss DC-link voltage control of the grid-side voltage source inverter (VSI) which controls active power flow from the machi...

many real time processes have complex, uncertain and nonlinear dynamics. boilers are nonlinear, time varying, multi-input multi-output (mimo) systems, whose states generally vary with operating conditions. the major problem in controlling that system is that its drum water pressure and steam flow dynamics include an integrator that results a critically stable behavior. conventional controller p...

In this paper, a novel current control technique is proposed to control both active and reactive power flow from a micro grid system fed by a renewable energy source through a single phase parallel-connected inverter. The parallel connected inverter ensures active and reactive power flow from grid with low total harmonic distortion even in the presence of non linear load. A p-q theory based app...

This paper introduces a novel Bi-directional DC-DC converter with artificial neural network controller (ANN).Bidirectional power flow is obtained by the same power components and provides a simple, efficient, and galvanically isolated converter. In the presence of DC mains the converter operates as buck converter and charges the battery. When the DC main fails, the converter operates as boost c...

On the basis of the linearized Phillips-Herffron model of a single-machine power system, a novel method for designing unified power flow controller (UPFC) based output feedback controller is presented. The design problem of output feedback controller for UPFC is formulated as an optimization problem according to with the time domain-based objective function which is solved by iteration particle...
