Abstract

Due to their evolved technological structures and operational concepts, the dynamical aspects of new power generation technologies such as solar photovoltaic (solar-PV) generators are significantly apart from the conventional technologies such as steam turbine generators. Solar-PV generators are among the most sustainable form of renewable energy sources; however their increased penetration level may cause many problems to the power system like high transients due to shading effect, harmonics, frequency and voltage regulation and islanding problems. There is also the problem of being intermitted and inertia less which make it more sensitive to grid disturbances.
The dynamical impact of the solar-PV technologies and their operational modes are given much attention for ensuring the security of power systems. In addition, the construction of adequate models of solar-PV generators for dynamic stability analysis of power systems needs to be considered for simplified, fast, and proper analysis of the impact of solar-PV generators on power grids. Also the availability of adequate reduced-order dynamic models of solar-PV generator is essential for fast assessment of the dynamic security of power systems as affected by the natural variations of solar-PV output.
This thesis presents a new maximum power point tracking technique (MPPT) to compensate for the usual drawbacks of conventional MPPT like perturbation and observation (I&P) and incremental conductance (IC), another technique to control the output active power will be presented and tested. Due to the solar-PV generator detailed model complexities a reduced order model suitable for stability studies will be presented and utilized to determine the maximum penetration level of the solar-PV generator; the reduced order model will consider the various operational modes of the solar-PV generators. A systematic approach for estimating the maximum penetration level (MPL) of solar-PV generators for securing the dynamic stability of power systems is also presented. Finally the results are validated through the ETAP simulation and they show the acceptable accuracy of the presented reduced dynamic models.
