MLI with Simplified Control Strategy for DER Integration with DS

Kelothu Naresh, This book presents MLI(Multi-Level Inverter) with simplified control strategy for DER(Distributed Energy Resources) Integration with DS(Distribution System). It gives basic concept of MLI, different control models, energy sorces from distribution side. Used control schemes for inverter. This book presents the integration scheme of distributed generation to distribution grid through multi-level inverter. Multi-level inverters like three-level and five-level were explained and integration schemes with both topologies were explained. Results were presented for proposed work showing voltage and current in DG, output of inverter, THD in DG current and power factor angle between DG voltage and current. Inverter is controlled with simplified control strategy which was explained with integration scheme. With integration of DG through multi-level inverters, THD reduces and rate of change in voltage also reduces at load.
