Abstract:
In recent times, the trend of using electric vehicles in transportation has become
more than ever. Electric cars are powered by an electric motor that is powered by a
battery, where they are recharged using an electric charger, and thus they need electric
charging stations to be charged.
This project studies the electric power network in the city of Hebron as a result of
adding seven electric vehicle charging stations distributed in the network using the
Electricity Analyzer (Etap), and aims to make strategic planning on the network and
make developments and improvements and study the resulting effects on the network
in order to develop appropriate solutions.
The essence of this project is to use etap which has a simulation feature that
allows us to analyze and study the state of the network more accurately.
In this project, different types of electric vehicles were used that contain batteries
of different capacities that can be charged using charging technology and charging
levels according to the approved international standards that are used in the stations
that have been added to the network by proposing scenarios to simulate the loads on
the network at times Different throughout the day and a different number of electric
vehicles.
This network suffers from large losses, as it was found that the amount of wasted
energy in the medium voltage network before adding the stations is 3.198%, which is
an acceptable value according to the standards of the International Electrotechnical
Commission (IEC).
In this project, different scenarios for loads on the network were applied to
analyze the energy flow and display losses in different cases. It was found that the
amount of wasted energy in the network at the highest load was 3.694% in addition to
the presence Increasing loads on some cables, distribution transformers and feeding
transformers for EV charging stations, and thus a scenario was proposed to solve the
problems that appeared on the network by redistributing the loads to the substations
and adding a new station to the network in order to reduce losses.
The results showed that the total energy losses could be reduced at the highest
proposed load on the grid as a result of adding electric vehicle charging stations from
3.694% to 3.0009%.
