Decomposition of Mega-Solar for Interconnecting to a Weak Power System

Amin Mohammadirad and Ken Nagsaka
Abstract—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.

Index Terms—Mega-solar, interconnection, weak power system, decomposition.
