In this paper, the proposed shunt regulator is presented. Compared with a series voltage regulator, the shunt voltage regulator gives wideband power supply rejection (PSR) and fast transient response at the expense of large quiescent current. In this paper, a novel shunt regulator architecture is proposed to achieve the genuine characteristic of a shunt regulator with small quiescent current. T...

With an increase in the penetration of renewable energy sources such as wind into power systems, operation and control voltage/reactive have become more complicated challenging than ever. As a result, reactive imbalance between generation demand instigates reduction system voltage stability. To deal with aforesaid scenarios, automatic regulator (AVR) static synchronous compensator (STATCOM) are...

The dynamic characteristics of converter-dominated systems are governed by controlling power converters and the interactions between converter conventional alternators. Frequency oscillations can appear under operation conditions caused phase-locked loop dynamics among control systems. may be poorly damped, which result in reduced generation, longer settling time, or disconnections sensitive co...

The second system of the IEEE second benchmark model of Subsynchronous Resonance (SSR) is considered. The system can be mathematically modeled as a set of first order nonlinear ordinary differential equations with the compensation factor (μ = Xc/XL) as a bifurcation (control) parameter. So, bifurcation theory can be applied to nonlinear dynamical systems, which can be written as dx/dt = F (x;μ)...

An application of the current search (CS), one of the most efficient metaheuristic optimization search techniques, to design the PIDA (proportional-integral-derivative-accelerated) controllers is proposed in this paper. The CS is applied to search for the optimum PIDA controller’s parameters. The obtained controllers are tested against nine benchmark systems collected by Åsström and Hägglund co...

This paper presents the design of two separate Continually Online Trained (COT) Artificial Neural Network (ANN) controllers for excitation and turbine control of a turbogenerator connected to the infinite bus through a transmission line. These neurocontrollers augmentheplace the conventional automatic voltage regulator and the turbine governor of a generator. A third COT ANN is used to identify...

This paper presents the design of two separate continually online trained (COT) neurocontrollers for excitation and turbine control of a turbogenerator connected to the infinite bus through a transmission line. These neurocontrollers augment/replace the conventional automatic voltage regulator and the turbine governor of a generator. A third COT artificial neural network is used to identify the...

The present article is a sequel of the article"Fislab the Fuzzy Inference Tool-Box for Scilab"and it represents the practical application of:"The development of the Fuzzy regulator with an input and an output in Fislab". The article contains, besides this application, some functions to be used in the program, namely Scilab functions for the fuzzification of the firm information, functions for t...

We derive the maximum entropy of a flow (information utility) which conforms to traffic constraints imposed by a generalized token bucket regulator, by taking into account the side information present in the randomness of packet lengths. Under constraints of maximum aggregate tokens and maximum aggregate bucket depth, information utility is maximized only if the generalized token bucket regulat...

This paper presents a four-stage DC/DC converter with high precision and small ripple utilized in an electronic power conditioner (EPC). The galvanically isolated topology contains four cascade connections: buck circuit, push–pull converter, voltage regulator. switches, as well the diodes output-side rectifier, operate zero-voltage switching (ZVS) zero-current (ZCS) modes at both switch off on,...
