| This thesis coven the sizing and validation of a number of novel efficient low cost dynamic error driven maximum photovoltaic power tracking controllers developed by Dr. A.M. Sharaf for stand-alone renewable photovoltaic and hybrid photovoltaic/wind energy utilization schemes. The dynamic error driven controllers ensure maximum photovoltaic power tracking near maximum power point (MPP) operation at all times under varying electric load, ambient temperature and solar irradiation conditions. Four stand-alone renewable photovoltaic and hybrid photovoltaic/wind energy utilization schemes developed by Dr. A.M. Sharaf are validated using low cost dynamic error driven maximum photovoltaic power tracking controllers namely: (1) Photovoltaic Four-Quadrant PWM converter PMDC motor drive scheme: PV-DC Scheme I. (2) Photovoltaic DC/DC dual converter scheme: PV-DC Scheme II. (3) Photovoltaic DC/AC six-pulse inverter scheme: PV-AC Scheme. (4) Hybrid renewable photovoltaic/wind energy utilization scheme: Hybrid PV/Wind Scheme.;The dynamic controllers require only the measured values of PV array output voltage and current signals in addition to the induction generator or load bus RMS current, RMS voltage and DC motor speed signals that can be easily measured with low cost sensors and transducers and also the dynamic controllers can be easily implemented with low cost micro controllers. The proposed low cost stand-alone renewable photovoltaic and hybrid photovoltaic/wind energy utilization schemes and dynamic error driven maximum photovoltaic power tracking controllers are digitally simulated and validated using the MATLAB/Simulink/SimPowerSystems software and are suitable for resort/village electricity application in the range of (1500 watts to 50000 watts), mostly for water pumping, ventilation, lighting, irrigation and electricity supply use in arid remote and isolated communities. |
