An Interline Dynamic Voltage Restorer (IDVR) to Mitigate Voltage Sags
Abstract: Nonlinear load are the vast source for voltage sags. Loads such as arc furnace, large variable frequency drives (VFD) Voltage interruptions can cause severe economic loss to the power system. To protect sensitive loads at the consumer side generally a DVR (dynamic voltage restorer) can be used. DVR is connected in series with the line by injection transformer and it is generally located at the distribution side. DVR is basically …

Topology, Operation and Control of Modular Multilevel Converter for Grid Application: A Review
Abstract: Modular multilevel converter (MMC) is a widely accepted technology for high voltage direct-current (HVDC) application. Due to its modularity, scalability, power quality, and no need of bulky filter on ac side, they are widely used as voltage source converters in HVDC applications. This paper presents a comprehensive study on MMC technology for grid applications along with different modulation techniques and voltage balancing strategies which are essential for the converter to …

Power Swing Detection and Out-of-Step Prediction Using the Equal Area Criterion
Abstract: During the operating conditions, the modern interconnected power systems are more subjected sudden changes, such as faults, network changes due to line trip outs, and disconnection of a large load or of a generating plant. Such disturbances create power swing among the other generators which forces the remaining generators to adjust and settle to new stable conditions. In some cases, the swings are so large that some generators run out …

Aspect of Power Transformer Design and Optimization
Abstract: Transformer is one of the most important components of power system. Preliminarily it looksa simple device but from analysis and innovative point of view, it is the big bank ofengineering, which comprises civil, mechanical, chemical and electrical engineering. It is thetime of taking challenges and respective solution of minimizing cost of transformer withoutaffecting customer specifications. This is only possible by design optimization process.Optimization is the process of making something better. …
