Power Quality Improvement in Utility Grid using Single Phase Micro Sources, DSTATCOM and Distributed Generators
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2013, Vol 1, Issue 7
Abstract
This paper proposes to improve the power quality in a utility connected grid by using converter based single phase micro sources. The voltage unbalance can be severe if single-phase rooftop mounted PVs are distributed randomly between the households. Moreover, there can also be single-phase nonlinear loads present in the system. The cumulative effect of all these will cause power quality problem at the utility side. To counteract this problem, we have proposed two different schemes. In this first scheme a distribution static compensator (DSTATCOM) is connected at the utility bus to improve the power quality. The DSTATCOM only supplies reactive power and no real power. In the second scheme, a larger three-phase converter controlled DG is placed that not only supplies the reactive power but also provides active power. The efficacies of the controllers have been validated through simulation for various operating conditions using MATLAB/SIMULINK.
