摘要
This article proposes an economic and power quality based control of distributed generation system in autonomous mode. The control strategy proposed here, feeds nonlinear load from photovoltaic and battery energy storage, with a diesel generator (DG) operated in on/off mode instead of continuous mode. The coordinated controls of voltage source converter and buck & x002F;boost dc/dc converter achieve the multiple objectives of harnessing maximum renewable power, maintaining battery state of charge, and continuous power supply to the critical loads, while maintaining the power quality within permissible limits as per the IEEE 519 standard. Furthermore, minimum fuel consumption and maximum fuel efficiency, are obtained while operating DG, along with maintaining its currents free from harmonics even in presence of nonlinear loads, using novel improved robust mixed norm based adaptive control technique. Simulation results and experimental validation of proposed strategy, prove its satisfactory performance under different scenarios.
