Power Quality and Enhancement Techniques: Research Gaps and Current Trends

The increased use of electricity-dependent devices has posed many concerns to the power industry. The devices like electric motors, printers, generators, transformers, computers, etc are widely used in today’s world. The electronic devices increase the non-linear load to the power system which leads to the power quality (PQ) issues by which the electrical devices may get affected with fluctuation causing equipment failure, power system failure, etc. In order to resolve the PQ related issues and harmonics mitigation occurred due to nonlinear load power filters were introduced in decades ago. This paper deals with the review of existing researches that uses power filters and other methods for power quality improvement. The paper also gives gaps and the current state of the art in the recent researches which have futuristic scope in the research domain.
