Abstract:
Energy and environmental issues on conventional
energy sources has been a serious concern due to greenhouse gas
emissions, depletion of energy resources and growing demand for
electrical energy. Microgrid is an innovative solution researches
are focusing as a sustainable energy supply system to utilize
reliable and clean energy sources. With the higher penetration of
solar PV, together with the increasing use of electronic loads and
Electric Vehicles, researches are focusing back on using DC
systems and thus, DC microgrids. The objective of this paper is to
present the designing of a control strategy for a 48 V radial
unipolar DC microgrid. Power control is the main factor that
decides the correct operation of a DC microgrid when
considering the power sharing between different types of power
sources where some being intermittent in nature. To verify the
performances of the proposed design and control scheme of the
microgrid, a simulation analysis is conducted using Matlab
Simulink. Results indicate proper operation of the designed DC
microgrid.
