Impact of solar-mounted truck on the grid

Sammanfattning: Sweden has a climatic goal to reduce the emission of greenhouse gases by 2045. One of the major contributors to carbon dioxide emissions is the transportation sector, out of which the major share lies in the heavy freight sector. There has been a huge shift towards electrification of transportation in the last decade, but it has been slow for heavy transportation. We can see that there are many electric vehicle charging stations around Sweden for heavy freights now. But the increase in dependency of traffic on electric power is a challenge for the electric grid, which leads to many power quality issues and capacity shortages. The introduction of Battery Energy Storage Systems (BESS) and the integration of Photovoltaics (PV) systems at charging stations are novel methods to reduce the impact of electric vehicle charging on the grids. Another technology, Vehicle Integrated Photovoltaics (VIPV) was developed as an add-on for powering the auxiliary services on the vehicles, though it was not much experimented in the heavy vehicle sector.  Passenger vehicle manufacturers like Lightyear and Sono motors have developed solar cars which increased the driving range. The technological development in the design and construction of solar panels led to novel ideas in the heavy electric vehicle sector as well. This not only reduces the need to create new infrastructures for generating power since the solar energy integrated charging stations normally take up large spaces where the solar modules are mounted but also provide enough space on the vehicle where the solar modules are placed without affecting the aerodynamics of the car.  The thesis is conducted to study the impact on the grid when solar hybrid truck, mounted with solar panels on top and sides are charged at the station. It is extended to the possibility of Vehicle-to-Grid on weekend as well to increase productivity and reduce the dependency on the grid during peak hours. The design and simulation part are conducted with the help of MATLAB Simulink.
