The stochastic behavior of PV together with high penetration have given rise to power quality concerns involving voltage dynamic issues such as undervoltage, overvoltage, sag and swell. To ensure the grid’s stability, various methods been practiced a proper sizing grid lines installation compensation equipment. However, these measures often require costs control complexity due additional equipm...

Mitigating switching overvoltages (SOVs) and conducting well-suited insulation coordination for handling stresses are very important in UHV transmission Lines. The best strategy in the absence of arresters is controlled switching (CS). Although elaborate works on electromagnetic transients are considered in the process of designing transmission systems, such works are not prevalent in day-to-da...

Wind energy is a good alternative to fossil fuels, as the use of fuels has seriously exacerbated emission greenhouse gases such carbon dioxide and greatly affected environment. Conventional AC wind farms transmission systems inevitably face problems involving reactive currents overvoltage in context large-scale, large-capacity, long-distance transmission. However, all-DC turbines, together with...

In low-voltage power networks with a large share of distributed energy sources, the phenomenon overvoltage is increasingly observed. Although it may be desirable to raise voltage value downstream network, in some cases upper allowable limit exceeded. The method eliminating rises commonly used Polish system installation protections, disconnecting source from grid. Such action reduces profitabili...

The biggest loss in the industry that caused to experience financial losses should have been target of achieving 90% - 100% production was a decrease up 40%, due machines not running excessive loads used resulting overvoltage disturbances, voltage drops or unbalanced voltages. To overcome monitoring tool and protection system are needed with method can cut off load automatically when disturbanc...

The high amplitude and steep overvoltage generated by the breaking of vacuum circuit breaker in wind farm damages inter-turn insulation transformer. There is a certain difference between simulation results traditional reignition model measured overvoltage. It necessary to improve simulate condition transformer more accurately then select appropriate protection measures. In this paper, based on ...
