Abstract:
This research concerns itself with the design and modeling of a microgrid incorporating
renewable energy sources like wind and solar resources and employing BESS to boost the microgrids stability and reliability. This research pertains to fundamental issues, for
instance voltage variation, frequency sensitivity, and load sharing especially during losses
in renewable generation, dynamic loads changes, and others from normal disturbances. In
numerous simulations undertaken in the ETAP, various possibilities were studied to
determine how the microgrid functions its capabilities with and without the incorporation
of BESS. Analysis of the results shows increases in BESS’s ability to reduce voltage
fluctuations, maintain the stability of the power grid during faults, and effectively control
for power discrepancies arising from variability in load or total generation. The stability
was also confirmed through enhanced voltage regulation in 132kV, 33kV and 11kV buses
and BESS is capable of immediate compensation in emergency situations. Furthermore,
based on economic analysis, the implementation of BESS led to the reduction of utility
cost by 36% after a year of implementation with a return on investment annually of 63.2%
and approximately 16 months payback period. As a result, this research provides a
framework where BESS can be integrated into microgrids adapting efficient and reliable
decentralized renewable energy system apart from the utility power. Thus, the findings
contribute to the development of the subsequent research and implementation of efficient
and sustainable energy systems
