Combined Energy Storage and Management Systems for Smart Grid oriented Renewable Energy Optimization

Abstract

This study presents an enhanced energy management system (EMS) to minimize energy costs and optimize storage in
hybrid solar and wind energy microgrids, incorporating battery storage and grid connectivity. The enhancement of
efficiency depends on a parameter known as a contribution factor, which allocates a sufficient quantity of the necessary
power from the battery according to the energy price of the primary grid. Various profiles are examined to improve
system efficiency. A load shift technique has been incorporated into energy management to optimize energy costs.
The system utilizes the efficiency of the components to calculate the energy expenditure precisely. Calculations have
been conducted at various load demand rates, demonstrating the advantages of the suggested energy control system
over the standard model in reducing energy price, degrading battery costs, and enhancing battery lifespan. The findings
indicate that employing a linear profile for the impact of components and transferring load yields daily expenses of
$67.3 for fuel and $0.75 for deterioration. These figures indicate a 24.2% reduction in energy expenses and a 90.4%
reduction in battery life cost relative to the traditional energy administration system, which does not account for power
from the grid or a change in the utilization of battery storage.
