Identification of intentional and unintentional islanding situations of dispersed generators (DGs) is one of the most important protection concerns in power systems. Considering safety and reliability problems of distribution networks, an exact diagnosis index is required to discriminate the loss of the main network from the existing parallel operation. Hence, this paper introduces a new island...

MODULARIZED MULTILEVEL AND Z-SOURCE POWER CONVERTER AS RENEWABLE ENERGY INTERFACE FOR VEHICLE AND GRID-CONNECTED APPLICATIONS By Dong Cao Due the energy crisis and increased oil price, renewable energy sources such as photovoltaic panel, wind turbine, or thermoelectric generation module, are used more and more widely for vehicle and grid-connected applications. However, the output of these rene...

The protection of conventional high voltage capacitor banks relies on an unbalance relay. However, investigating the faults requires time and human resources. To address this issue, characteristics system parameters were analysed in study by performing simulations using power systems computer-aided design software. modelled based a 115-kV-system Electricity Generating Authority Thailand. case s...

in distribution systems, in order to diminish power losses and keep voltage profiles within acceptable limits, network reconfiguration and capacitor placement are commonly used. in this paper, the hybrid shuffled frog leaping algorithm (hsfla) is used to optimize balanced and unbalanced radial distribution systems by means of a network reconfiguration and capacitor placement. high accuracy and ...
