Abstract:
This study discusses the design and modeling of a microgrid system that is comprised of wind
turbines, solar panels, and battery energy storage units (BESU). The purpose of the proposed
system is to offer a consistent and dependable supply of power by integrating renewable energy
sources with BES units in order to overcome the intermittent nature of these sources of energy.
Continuity of power supply to vital loads is ensured by the microgrid's ability to function in either
grid-connected or island mode, depending on the situation. The findings of the simulation indicate
that the suggested system has the potential to achieve high levels of efficiency and reliability while
simultaneously lowering carbon emissions and cutting down on energy expenses. In addition, the
control strategy for the system is developed utilizing a hierarchical structure, which ensures the
most efficient functioning of the photovoltaic, wind, and battery energy storage units. In order to
increase the power quality, stability, and efficiency of this microgrid system, it is managed and
regulated using an improved power management (IPM) algorithm. The efficiency of the proposed
system is examined under a wide variety of scenarios, including the unpredictability of the weather
patterns and the erratic nature of the electrical grid. According to the findings of the research, the
PV-wind-BES-based microgrid system has the potential to be a workable option for off-grid and
isolated locations that demand a dependable and environmentally friendly source of power.
