—This paper represent interconnection of 16
Megawatt [MW] Mega-Solar with a dedicated control system to
a grid. The Photovoltaic (PV) are connected to DC/DC
buck-boost converter with Perturb and Observe (P&O)
Maximum Power Point Tracking(MPPT) controller. For
controlling the DC/AC inverter, reference controller
(abc-controller) and hysteresis current control are used. When
amount of the connected Mega-Solar increased, as a result of the
simulation, it become obvious that the reactive power of main
grid (weak power system) is consumed and the voltages rise at
the connected bus. In this study, first we controlled the voltage
and current with dedicated control system and get maximum
power from Mega-Solar. Second, we interconnect our
Mega-Solar site to IEEE 30 Bus Test System (Weak power
system) as main grid and by decomposition control strategy
solved the problem of reactive power shortage. In this paper, all
simulation designed in MATLAB/SIMULINK. For simulation
of an actual power system, for the first time, a simulation model
of the IEEE 30 Bus Test System on the MATLAB/SIMULINK
environment its developed and its effectiveness is verified
through various simulation results.
