Abstract [en]

This master thesis project represents an improved model of a grid connected three phase, singlestage PV system implemented in SIMPOW program. The proposal model consists of a PVgenerator employing a PWM converter in order to interface the AC network. The main objectiveof the project is to introduce the main components of the represented model as well as therequired controller schemes. In order to achieve the accurate performance of the PV system withrespect to the integration grid, both AC and DC side network are equipped with controllerfacilities, optimizing the system operation. The control facilities, implemented on the DC side,are mainly focusing on regulation of the output DC voltage of the generator depending on therequirements of the system. The newly proposal MPPT model represents an improvedoptimization strategy for the DC voltage extraction corresponding to various environmentalconditions. The AC side controllers are designed considering the PV system dynamiccontribution on the grid as well as its participation in reactive power provision to the network. Tostudy the accuracy of the dynamic operation of the system, several case studies have beenperformed on AC and DC side. The results of those studies have been discussed considering theirsimulation diagrams.
