Thermoelectric generators (TEGs) are used for the direct conversion of heat energy into electricity. Given that there is an extreme concentration of heat present on house roofs, the application of TEGs on these locations is feasible. This study involves the modeling of thermoelectric generators on house roofs through the use of simulations and an actual prototype. Simulations were done using the matrix...
Conventional switches are usually controlled by a manually defined algorithm implemented in the network processor. The conventional methods of control are fast, reliable and transparent. The article deals with alternative method of switch control - based on a neural network, focused on Quality of Service. The article describes the designed model, simulation and summarizes the results.
This work treats the study of the power balance of a high voltage power supply for microwaves generators, used in various industrials applications, from its modeling with Matlab-Simulink. The power supply uses a single-phase high voltage transformer with magnetic shunts supplying a cell voltage doubler and current stabilizer composed of a capacitor and a diode. This doubler supplies in its output...
Performance optimization, system reliability and operational efficiency are key characteristics of smart grid systems. In this paper a novel model of smart grid-connected PV/WT hybrid system is developed. It comprises photovoltaic array, wind turbine, asynchronous (induction) generator, controller and converters. The model is implemented using MATLAB/SIMULINK software package. Perturb and observe...
In the paper, it is shown how is electricity trading (including congestion) influence on market participants in each area. Market participants we focus here are generators (traders) and suppliers (customers). It is shown three examples (models) with four connected areas (regional market), where this benefits and losses for the involved parties are presented - impact on competitiveness. Four area example...
This paper introduces a modeling method of Three-stage Brushless Synchronous Machines. Three-stage Brushless Synchronous Machines' model is built by SimPowerSystems module and SIMULINK module in MATLAB. This model can be used to simulate both in electromotion-state and generating state. Compared with the common model, this model have the advantages of faster simulation speed and more intuitive.
Doubly-Fed Induction Generators (DFIG) are commonly utilized in wind farms nowadays due to their advantages as compared with single-fed ones. Control complexities and their unique characteristics may, however, raise different problems during abnormal or faulty operating conditions. In this paper, an integrated simulation for DFIGs in wind farms is presented for protection application purposes in particular...
The generator power have related with the wind turbine torque heavily. The wind speed, the rotor speed, the pitch angle and the inherent parameters of wind turbine can influence the wind turbine torque. Different torque curves in different operation can be simulated by Simulink software of Matlab. However, this method needs wind turbine's parameters which aren't usually obtained to construct the model...
Power systems stability has been analysed specially due to the quick increasing of wind power penetration all around the world, specific in USA and Europe. This research presents the small signal stability analysis based on Kundurpsilas theory but specifically for wind turbines with squirrel cage induction generators - SCIG, understood as a widely accepted and applied for many researchers, power system...
