Abstract
Batteries are the power tank of renewable energy power systems. They play
the role of power supply when the renewable energy power sources are not available.
This thesis demonstrates the development of a new battery charge controller for
renewable energy systems. A comprehensive review of the conventional controllers
is conducted to collect their contributions, advantages, and disadvantages for
comparison and validation.
The new controller designed based on a novel maximum power point tracking
(MPPT) technique. The new MPPT technique utilizes a smart algorithm and is
optimized using the genetic neural algorithm. In addition, the proposed controller
utilizes a multistage charging algorithm in order to minimizing the charging time.
The components of photovoltaic generator system are introduced and
mathematically modeled including the control and optimization methods. The
charge controllers design aspects, functions, and charging control methods are
discussed. Consequently, the new controller is modeled based on complete
mathematical models.
In order to determine the performance parameters and evaluate the validity
and efficiency of the new controller, a complete PV system is modeled and simulated
using MATLAB/SIMULINK. Moreover, a complete experimental prototype is
implemented. The simulation and experimental results are compared for validation
and clarification. They strongly agree on that, under all test conditions, the new
controller tracks the target maximum power point (MPP) more faster than the
traditional methods. In addition, it can tracks successfully the global maximum
power point (GMPP) in all partial shading conditions. Moreover, the charging time
is significantly reduced.he thesis is divided into six chapters organized as follows:
Chapter One introduces the components of a general photovoltaic system.
Moreover, it reviews the recent publications and contributions in the scope of
maximum power point tracking and charging control methods for renewable energy
systems. In addition, it lists the thesis objectives and outlines.
Chapter Two covers the mathematical model of general photovoltaic systems and
the control and optimization methods.
Chapter Three demonstrates the theory, design aspects, and control methods of the
battery charge controllers.
Chapter Four shows the complete modeling, simulation, and validation of the
proposed system.
Chapter Five presents a complete experimental version for the proposed system
including all test cases and validation.
Chapter Six concludes the work and states the recommendations for future work.
