In this paper, a unique design for wind farm and solar PV systems connected to a DC grid is discussed. The proposed DC grid-connected system is more effective, affordable, and dependable than the existing AC grid-connected model for solar and wind farms because of its smaller size and easier paralleling procedures. The AC grid-connected model suffers from issues with frequency instability, voltage stability, operational instability, and the control and compensation of active and reactive power. The proposed hybrid controller ensures stable DC output under grid side disturbances and maximizes power extraction from the input. The DC-DC converters used in this system are optimally employed under both steady and fault conditions. Utilizing DC-DC converters in this configuration guarantees three key benefits: (1) improvement of the voltage profile of the electrical grid during faults, (2) efficient power extraction from PV and wind farms, and (3) overall system reliability. MATLAB/Simulink simulations are used to assess how well the suggested design performs under various test situations.

摘要

In this paper, a unique design for wind farm and solar PV systems connected to a DC grid is discussed. The proposed DC grid-connected system is more effective, affordable, and dependable than the existing AC grid-connected model for solar and wind farms because of its smaller size and easier paralleling procedures. The AC grid-connected model suffers from issues with frequency instability, voltage stability, operational instability, and the control and compensation of active and reactive power. The proposed hybrid controller ensures stable DC output under grid side disturbances and maximizes power extraction from the input. The DC-DC converters used in this system are optimally employed under both steady and fault conditions. Utilizing DC-DC converters in this configuration guarantees three key benefits: (1) improvement of the voltage profile of the electrical grid during faults, (2) efficient power extraction from PV and wind farms, and (3) overall system reliability. MATLAB/Simulink simulations are used to assess how well the suggested design performs under various test situations.
