Improving power quality in micro-grid

Unified Power Quality Conditioner (UPQC) has been a favourable candidate for high performance power conditioning devices due to its feasibility and ability to mitigate all power quality problems. It will be very useful in the future micro-grid systems where power quality issues will be more pervasiv...
