Power Quality Issues in Commercial Load - Impact and Mitigation Difficulties in Present Scenario

Power quality in electric power grid and at consumer side network is a very significant contributing factor to the development of any country in terms of economics. It is essential to achieve this through maintaining the system power quality. The major division of loads categories are residential, commercial and industrial type. In this paper, a commercial load is taken as a case study and covering wide range of power quality issues related to harmonic distortions, low power factor, unbalancing, triplen harmonic current and high neutral current problems. In the era of growing mitigation techniques, it is very difficult to choose one and find best one. Depend on various parameters the best suitable solution is split capacitor shunt active power filter is proposed and validate with MATLAB simulation to verify the results. The impact and power quality issues in commercial load is ignored earlier but now it’s time to pay attention on such type of loads to minimize the bills and other bad power quality dependent expenses. This case study offered a detailed power quality analysis and solution including economic analysis to go for easily and readily implementable with economical way out.
