چکیده مقاله
Abstract—Nowadays, due to the increasing price of fossil
fuels and its decreasing resources on the one hand and
environmental pollutions on the other hand, use of electric
vehicles (EVs) has been increased. Charging EVs has
imposed new loads on power systems. These new and
major loads along with the deregulation of power systems,
which introduces new uncertainties to grid, have caused
new challenges for the frequency control and stability of
power systems. Use of EVs as moving batteries is one of
the ways for dealing with this problem. In this method, EV
charging is controlled and, when necessary, EV battery is
discharged in grid. This concept is so-called vehicle to grid
(V2G). V2G concept is employed in this study for the
control of a smart deregulated grid frequency. For this
purpose, an optimized fuzzy controller is used to control
EVs. Using the proposed method, charging or discharging
batteries is carried out with respect to grid frequency and
battery state of charge (SOC). To investigate the proposed
approach, a modified IEEE 39-bus system in the presence
of renewable energy resources is assumed. Then, this
system is converted into a three area system in order for
the frequency analysis. Investigating the performance of
the proposed method for the charging of EVs is done in
another part of paper. Simulations are carried out in
MATLAB/SIMULINK environment and their results
illustrate good performance of the proposed method in the
frequency control of deregulated system and EV charging.
