This work describes the development of a fuzzy logic based control system capable of governing multiple thyristor-controlled series capacitors (TCSCs). The main purpose of the presented coordinated control system is the improvement of active power flow con ...
We investigate the performance of sparsely-connected networks of integrate-and-fire neurons for ultra-short term information processing. We exploit the fact that the population activity of networks with balanced excitation and inhibition can switch from an ...
This work describes a development of a control system and control strategies capable of governing multiple flexible AC transmission system (FACTS) devices. The main purposes of the presented coordinated control system are to remove overloads and to achieve ...
With a given power demand pattern supplied by a set of pulverized fuel coal- fired (PC) power generation units at various locations, different power dispatching solutions will result in different fuel consumptions, CO2 emissions, and power generation costs ...
The aim of the proposed paper is to extend the well known complex torque coefficient method for synchronous machine rotor oscillations, to auxiliary devices (voltage regulators, power system stabilizers (PSS), ...) in electrical networks. To illustrate the ...
Transient stability investigations consist of studying the rotor oscillations of generators (electro-mechanic oscillations, 0.1-2 Hz) after the occurrence of a fault of large amplitude, e.g. short circuit. The goal is to indicate if the generators are capa ...
This paper examines the use of thyristor controlled series capacitors (TCSCs) for the redistribution of active power flows (PFs) in a transmission network and presents a simple model of a hierarchical coordinated control system for multiple devices. The TC ...
The paper deals with the main problems to solve in order to simulate precisely the behavior of complex power systems with mixed elements (power components and digital regulation devices). A simulation tool developed at the Swiss Federal Institute of Techno ...
Similar to the classical solution of hydraulic pump-turbine plant, new means for accumulation of eletrical energy are given for lower but respectable quantities by the so called BESS (Battery Energy Storage System) and SMES (Super conducting Magnet Energy ...
The most critical viewpoints and requirements of potential users are discussed, and a practical and descriptive definition of what an expert system does (rather than what it is) is proposed. The costs and benefits of its adoption are assessed, and lessons ...
