Figure 1: Layout of Two Area System
Inertia Emulated strategy is taken in to account where this model helps to increase the system
inertia. The area-2 considered is a microgrid which consists of distributed generators like
wind generation, solar and diesel generator. Where the diesel generator works continuously
in the microgrid but the solar and wind generations are intermittent in nature and depends
on the climatic conditions like solar irradiation and wind velocity. Along with the DGs
an aggregated electric vehicle model is placed in the area-2, which can store excess power
available in the battery with the help of G2V operation. During power deficits the battery in
the EV discharge its energy to the grid with the help of V2G operation thus the intermittency
and inertia of the microgrid i.e., area-2 is improved. The microgrid performance is further
enhanced by the interconnection with area-1. Here Area-1 is considered as main-grid where
area-2 is a microgrid. Thus a model with microgrid integration with the main grid is depicted.
The load disturbances and power mis-matches in the system can overcome with the help of
storage unit i.e., EV model and also with the help of interconnection between the two areas.
Thus the system can perform reliably and stably even during any disturbances. Further to
improve the performance an advanced powerful controllers are incorporated in both the areas
which helps in reducing frequency fluctuations during power mismatches and also keeps the
tie-line power exchanges as constant.
