摘要：Generally the micro grid system is a large scale power distribution network of very complexarchitecture, satisfying the needs of common electrical loads. This giant class power system lacks in ability to serve thehilly, remote and terrain regions by its power due to their hard striking non-homogeneous geographical conditions,under which renewable energy based Off-Grid Hybrid Power System (OG-HPS)s, were emerged as the reliablealternative. But very often due to the time based fluctuations of the renewable power levels and frequent line faults, thepower quality of OG-HPS may be degraded. As an eternal solution to this ever teasing problem, in this paper weproposed a robust IMDGU and ZRU based approach for power quality enhancement and regulation in OG-HPS.Theproposed approach was realized with an Intelligent Module Distribution Generation Unit(IMDGU) as a core processingunit, internally which comprises a Phasor Measurement Unit(PMU) intended for an instantaneous detection andisolation of the network line faults, a Power Quality Regulation Unit(PQRU) meant for power quality restoration and aZener Regulation Unit(ZRU) for power quality regulation as sub-core processing units. As a prime commandingmodule, the IMDGU will provide an adaptive fault security, real-time correction and regulation of the distributedpower quality by properly steering the operational control of all sub-core processing units. The proposed approach iscoded, simulated and tested in the Mat lab Environment. Simulation results adjudged that the proposed approach is thebest in all aspects and outperforms all the existing techniques.
