Power quality analysis in hybrid power resources in a distributed generative system. Different power failures may cause huge damage for the end user the failures should be compensated as earliest. MC-UPQC is a new power quality conditioning system for multibus/multifeeder systems capable of simultaneous voltage and current compensation. Several series voltage source converters are used in this configuration, as well as one shunt voltage source converter (shunt VSC). As well as compensating for supply-voltage and load current imperfections on the main feeder, the system can also compensate for supply voltage imperfections on adjacent feeders. DC-link capacitors are shared among all converters in the proposed configuration. In this way, sag/swell and interruptions can be compensated by transferring power between feeders. Simulations are used to illustrate the performance of the MC-UPQC and the control algorithm named advanced wolf pack algorithm (AWPA). Results showing an accuracy of 98.8% of power quality compensation with the proposed work.
