Power quality is always an important issue within the area of power systems. According to a Copper Development Association survey, the cost of poor power quality is in excess of $100 billion dollars a year. With the wide spread of distributed renewable energy systems, the poor power quality problem is expected to be even worse. Also with the increase number of ‘modern’ non-linear loads, mainly Switch-Mode...
This paper presents a flexible control technique for power electronics converters, which can function as an active power filter, as a local power supply interface, or perform both functions simultaneously. Thus, it can compensate for current disturbances while simultaneously injecting active power into the electrical grid, transforming the power converter into a multifunctional device. The main objective...
Renewable energy is gaining its importance widely on because of continuous degrading of conventional energy resources. Due to the intermittent availability of renewable energy sources which makes the system variable in nature, the involvement of power electronic components gain its importance. This paper investigates the various methods practiced in power electronic interfaces to tap energy from hybrid...
The following topics are dealt with: power converters; custom power devices; electrical drives; FACTS; deregulation; smart grid; harmonic filters; electrical engineering applications; distribution system; HVDC; power quality; power electronics; power system planning; renewable energy; metaheuristic techniques; and power system protection.
This paper presents a comprehensive review of power quality challenges under high penetration rate, fluctuation and imprecise prediction of incoming energy provided from different types of renewable sources. Power electronics devices such as active and hybrid filters topologies as well as different harmonic extraction techniques, and advanced type of controllers are classified, evaluated and discussed...
