ABSTRACT:
This paper presents an isolated
microgrid, with synchronous generator(SG) based diesel generation (DG) system in
combination with solar photo-voltaic(PV). The DG supplies power to the load
directly, and a battery supported voltage source converter (VSC) is connected
in shunt at point of common coupling (PCC). The PV array is connected at
DC-link of the VSC through a boost converter. A high order optimization based adaptive
filter control scheme is used for maintaining the quality of PCC voltages and
source currents. This controller makes the waveform free of distortion, removes
errors due to unbalances, corrects the power factor and makes the source
current smooth sinusoidal, irrespective of the nature of load. MATLAB/Simulink based
simulation results demonstrate satisfactory performance of the given system.

CONCLUSION:
An isolated SG based DG and PV hybrid
micro-grid has been presented here, with a battery suppported VSC connected at
PCC. Three-phase adaptive control is used for power quality improvement through
VSC. The given system and control have been simulated in MATLAB/Simulink
environment and results demonstrate their satisfactory performance in both
steady state and dynamic conditions.
