Modern electrical power systems now require the spread of microgrids (MG), where they
would be operating in either islanded mode or grid-connected mode. An inherent mismatch between
loads and sources is introduced by changeable high renewable share in an islanded MG system
with stochastic load demands. The system frequency is directly impacted by this mismatch,
which can be alleviated by incorporating cutting-edge energy storage technologies and FACTS
tools. The investigated islanded MG system components are wind farm, solar PV, Electric vehicles
(EVs), loads, DSTATCOM, and diesel power generator. An aggregated EVs model is connected to
the MG during uncertain periods of the generation of renewable energy (PV and wind) to support
the performance of MGs. The ability to support ancillary services from the EVs is checked. DSTATCOM
is used to provide voltage stability for the MG during congestion situations. The MG is studied
in three scenarios: the first scenario MG without EVs and DSTATCOM, the second scenario MG
without DSTATCOM, and the third scenario MG with all components. These scenarios are addressed
to show the role of EVs and DSTATCOM, and the results in the third scenario are the best.
The system voltage and frequency profile is the best in the last scenario and is entirely satisfactory
and under the range of the IEEE standard. The obtained results show that both EVs and DSTATCOM
are important units for improving the stability of modern power grids. The Matlab/Simulink
program is considered for checking and validating the dynamic performance of the proposed configuration
