Abstract:
Solar energy is the most emerging renewable energy. Applications of solar energy are increasing
for both gird connected and standalone system. Large power grid connection solar systems are
developed by giant power companies. But standalone system can be established by normal person
at available places of roof of house, office, hospitals, schools etc. That’s why they are becoming
much popular than others.
At an area of 1000 sq. feet, 8 kWp solar system can be installed. Before install rooftop optimal
rooftop area calculation is required. Once installed rooftop roof cannot be used for most of other
purposes. In this report standalone as well as gird connected solar system are designed and
simulated in MATALB. MPPT being the essential part of solar photovoltaic system is simulated
using Incremental conductance plus integral regulator technique in MATLAB environment in
chapter 4. For grid connection Vdc control and feed forward control is used. Results are shown in
chapter 8. A boost DC-DC converter and inverter are employed to achieve this goal. To implement
the system in real time hardware FPGA controller is used. FPGA uses HDL (Hardware Description
language) to describe the system.
