Systems Modeling And Economic Analysis Of Photovoltaic (Pv) Powered Water Pumping Brackish Water Desalination For Agriculture, Michael A. Jones
Systems Modeling And Economic Analysis Of Photovoltaic (Pv) Powered Water Pumping Brackish Water Desalination For Agriculture, Michael A. Jones
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The objective of this study was to determine the economic viability of solar powered water pumping and desalination systems for agriculture. Growing global demand for agricultural production has put increased pressure on limited freshwater resources in various locations around the word. Many areas have low quality groundwater resources that have not been utilized for agriculture due to limited availability to electricity, high operational costs of diesel generators and the economics associated with water pumping and processing. Reverse osmosis is a desalination technology that removes salts and other minerals from low-quality water, making it fit for drinking or irrigation. Reduced costs …
Control Of Grid-Connected Photovoltaic Systems Using Fractional Order Operators, Hadi Malek
Control Of Grid-Connected Photovoltaic Systems Using Fractional Order Operators, Hadi Malek
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This work presents a new peak seeking strategy for maximum power point operation using fractional order operators in the three-phase grid-connected photovoltaic systems. Moreover, fractional order controllers have been implemented in the voltage and current control loops. The simulation results and theoretical analysis indicate that the proposed fractional order control strategy improves the efficiency of the system by reducing the total harmonic distortion of the injected current to the grid and increases the robustness of the system against uncertainties. Additionally, the proposed maximum power point tracking algorithms provide more robustness and faster convergence speed under environmental variations than other maximum …
