INTRODUCTION
1.1 Motivation
Solar energy is known as a s green and endless energy ource. In the
21st century, solar energy has become more and more one of the most
important sources for human [1, 110]. Compared to other energy sources such
as hydroelectricity, wind power, thermal power, nuclear power, solar energy
has some of the following characteristics: no environmental pollution, high
safety, and endless reserves. Mooreover, it can be distributed everywhere in
wide power ranges (from a few W to hundreds of MW). If 0.1% of solar
energy on the global area is converted into the electricity with an efficiency
of 5%, it is estimated that 5.6 × 1012 kWh can be achieved each year,
equivalenst to 40 times the current generation of electricity on over the world.
In order to enhance the efficient of exploitation and use of solar
energy, the Prime Minister issued Decision No.11/2017/ QĐ-TTg encourages
the development of solar power projects in Vietnam. This is a big opportunity
to push the development of this energy source.
Up to now, the research and development of solar power systems is a
very necessary. The solar energy system has been become increasingly
completed more and more. There are some main trends in research and
development of solar power systems, such as improving optical-electricity
efficiency, building large capacity systems, setting up parallel safety electric
network. In the future, solar energy will become a main source of energy that
supports for some gradually exhausting energy sources such as coal, oil and
gas and water.
1.2 Objectives and content of the research
The objective of the thesis is to design a solar power system with
optimal power in order to enhance the opening efficiency of this system. The
content of the research is given as follows:
- Overview of the solar power system.
- Building a model of solar power system including components in the
system such as PV cell, DC / DC converter, SVPWM inverters, measurement
and control system ...
- Research and develop new algorithm-solution to track Maximum
Power Point (MPPT- Maximum Power Point Tracking)
- Building simulation model on computers.
