Power quality improvement in LV networks using distributed generation

The paper presents how power quality (PQ) can be improved in LV networks with distributed generation by using certain aspects of the sources, i.e. inverters and advanced controllers. This is demonstrated through simulation with PSCAD/EMTDC. PSCAD models of the loads, distributed sources and controllers are discussed. A model of measurement blocks is also proposed for power quality assessment. Some results of simulation are presented, which show the effectiveness of compensation.
