This study presents a voltage generation behavioral analysis of the thermoelectric module (TEM) in a transient condition. Two configurations module is carried out to perform the observational analysis of the TEM; which is single TEM and multi stage TEM. For the multi stage TEM, another two arrangements is executed by cascading three and six TEM subsequently. In this real TEM application, both TEM's...
This paper presents modeling, simulation and performance evaluation of grid integrated photovoltaic (PV) with battery energy storage system (BESS). The battery energy storage provides additional benefit for DC bus voltage regulation, where it is interfaced to the common DC bus of the PV power conversion system. A control method for state of charge and BESS charge/discharge is proposed to ensure an...
This paper proposes an algorithm based on the use of the S-transform for time-frequency analysis of the capacitor-switching transients. With no prior knowledge about system parameters, the time-frequency analysis of the voltage and current transient signals due to switched capacitor banks are used to simply but accurately estimate the relative location of the switched capacitor whether it is upstream...
This paper analyzing influence of distributed generation (DG) on transient stability of power system network operating parallel with large renewable energy resources (RES) power plant. The study is performed in hypothetical power system network envision in the future which contains a large number of DG. Network behavior when subjected to disturbance is compared with different level of DG penetration...
In this paper, analysis impulse voltage distribution in transformer winding, and winding of the voltage impulse response with a standard full wave and clipped wave especially at the ends of the entanglement presented. Compared with experimental data EMTPDC simulation, the result of t <;1.0 μs voltage difference occurs. For t >; 2.0 μs was obtained near the same voltage large, between experimental...
This paper concerns with transient stability control which is part of transient stability assessment which needs to be considered so that the power systems remained intact when failures originating from faults occurred in power systems. Conventional UFLS system is designed to retrieve the balance of generation and consumption following disturbances occurrences in the system. In UFLS method, whenever...
This paper presents a fast and accurate method to determine the available transfer capability. The Ralston's method is used to predict the two trajectory points of voltage magnitude, power flow and maximum generator rotor angle difference. Then, the cubic-spline interpolation technique is used to accurately trace the P-V, P-S or P-Δδ curves between two points of trajectory. The P-V, P-S and P-Δδ curves...
This paper presents the application of S-transform and rule based system for diagnosing power quality problems which are related to voltage disturbances. Such voltage disturbances can be caused by permanent or non permanent faults. A permanent fault causes permanent damage and power interruption to the customers whereas a non permanent fault can be categorized as either transient or incipient faults...

This paper presents transient stability assessment of a large actual power system using the probabilistic neural network (PNN) with enhanced feature selection and extraction method. The investigated large power system is divided into five smaller areas depending on the coherency of the areas when subjected to disturbances. This is to reduce the amount of data sets collected for the respective areas...
This paper presents transient stability assessment of a large practical power system using two artificial neural network techniques which are the probabilistic neural network (PNN) and the least squares support vector machine (LS-SVM). The large power system is divided into five smaller areas depending on the coherency of the areas when subjected to disturbances. This is to reduce the number of data...
