Modeling and simulation of grid-connected solar photovoltaic systems with D-statcom and dvr to improve stability in distribution system

Electrical utilities face problems such as the rising cost of electricity, aging equipment, increasing demand for electricity, regulating frequency, and the difficulties of incorporating renewables into the grid. The accumulated global photovoltaic (PV) particularly the installation of Grid-Co...

The accumulated global photovoltaic (PV) particularly the installation of Grid-Connected Solar Photovoltaic (GCPV) systems has been exponentially expanding around the world.

The purpose of this project is to model and simulate 100 kW and 250 kW solar PV systems that are connected to the utility distribution system with and without Distribution Static Synchronous Compensator (D-STATCOM) and Dynamic Voltage Restorer (DVR) under normal and faults condition in MATLAB/ Simulink. The test systems consist of a PV array that is connected in series and parallel modules, a DC-DC Boost Converter, Maximum Power Point Tracking (MPPT) control, DC-AC inverter, inverter control, filter, three-phase load, distribution transformer, and grid equipment.
