Özet
Renewable energy sources (RES) are becoming increasingly popular for electricity
generation for most global electric power grids. Governments, consumers, and investors
have recognized hybrid photovoltaic (PV) and wind turbine (WT) storage system
technologies as viable options for investigating power demand and reducing carbon
emissions from conventional sources. Utility workers may be harmed if they fail to notice
that a circuit is still powered in an islanding situation. This occurs when renewable energy
sources feed electrical power despite losing external electrical grid power. This thesis
proposes modified maximum power point tracking based on fractional order proportional
integral (FOPI) controller to harvest the maximum power from wind and PV systems under
critical conditions. In order to solve the islanding problems that arise when hybrid
photovoltaic, wind turbine, and battery storage systems lose connection to the grid, an
improved droop controller based on the maximum power of the PV system for antiislanding and investigating an accurate power-sharing is proposed in this work as a solution
to these problems. Power set-points for inverters can vary when operating in grid-connected
mode but must all be adjusted when operating in islanded mode. When operating in gridconnected mode, a hybrid system either draws power from or sends power to the primary
grid depending on generation and load needs and market policies that optimize efficiency
and cost. The suggested hybrid PV-wind-battery system's performance is assessed using
the Matlab R2021a program. The outcomes verified the proposed controller's potential to
limit DC link voltage while enabling gearless mode transfer. The energy management system (EMS) is tested in both grid-connected and islanded modes of operation to
demonstrate the efficiency of the proposed droop control and the EMS-based battery
controller. The total harmonic distortion of the output current at the common coupling point
was reduced to 1.98%, and the efficiency of the proposed hybrid system reached 97.5%.
