| Summary: | Power quality control still remains as one of major research topic in power engineering.
Weak power quality affects the reliability and efficiency of the utility and consumers. One of
the contributing factors is voltage unbalance which could potentially affects sensitive
equipment such as electronics and induction motors. With the use of hierarchical control
having primary and secondary control, this paper will introduce the use of voltage unbalance
compensation and negative sequence current feedback in an islanded microgrid to improve
overall power quality. With the installation of proportional integral (PI) controllers in each
individual Distributed generator (DG), it is able to exchange data with its neighbouring DGs.
A total of 3 DGs will be connected to the point of common coupling (PCC) in parallel with
simulation of unbalanced loads using MATLAB. |
