Abstract
A fundamental change toward a cleaner and more sustainable energy landscape can be seen in the rapid growth of renewable energy sources like Photovoltaic (PV) and wind power. Adopting these resources has numerous benefits, such as decreased greenhouse gas emissions, decreased operating costs, and improved energy security. Renewable energy sources diversify energy portfolios, lessen reliance on fossil fuels, and help to mitigate the effects of climate change. However, these resources’ sporadic nature presents a substantial issue. Production of PV and wind energy is dependent on factors like time of day and weather conditions like the availability of sunshine and wind speed and consistency. Energy generation becomes more unpredictable as a result of this intermittency, which may affect the reliability of the grid. Despite this drawback, energy storage options are consistently being created to efficiently handle and control the intermittency issue.
Thankfully, both locally and globally, the use of Electrical Vehicles (EVs) is rapidly increasing. The goal of this study is to enhance the performance of the power distribution network by utilizing the expanding of EVs sales. By injecting active power from EVs to the system during certain time periods, the major goal is to reduce total power losses and minimize the Total Volatge Deviation (TVD). The research uses the Teaching-Learning Based Optimization (TLBO) method to do so. Using a modified IEEE 33-Bus system, this approach finds the ideal size and placement for active power injections from EVs. The integration of renewable energies (RE) and its fluctuating power output are also taken into account in the study.
This study examines sixteen different scenarios to determine how EVs’ injected power affects the distribution system. These scenarios demonstrate the importance of EVs as active power sources. Four of these include the use of RE sources together with standard system loading, whereas the remaining four do not have any generation from RE. Eight additional examples represent higher loads by 50%. This all-encompassing strategy makes it possible to thoroughly examine the advantages of integrating EVs and RE into the electricity distribution system.
In summary, the rapid uptake of electric vehicles presents a special opportunity to improve the performance of the power distribution system. It is possible to reduce power losses and improve voltage profiles by maximizing the use of active power from EVs and incorporating with the existence of renewable energies. The conclusions of this research shed light on the anticipated benefits of this strategy.
