摘要

At the present time, one of the significant focuses of power system optimization is on coordinated management of distributed energy sources for the minimization of operational expenses in low-voltage microgrids. This paper suggests a two-level optimization scheme with the objective of curtailing the overall generation costs of microgrid (MG) as well as expanding the profit of the distribution company (DISCOM). The MG examined here comprises of three conventional fossil-fueled generators, a fuel cell, a solar photovoltaic unit, a wind power unit, and a battery energy storage device. The overall cost of generating MG incorporates costs like fuel, depreciation, operation and maintenance, and emission penalty costs. This work suggests an incentive-based demand response control procedure that is guided by customers’ willingness to curtail the loads for incentives. The first level of optimization utilizes the incentive-based demand response (IBDR) method to optimize DISCOM revenue, while the second level of optimization curtails generation cost with respect to the reduced load for MG optimization. The recently designed RIME optimization algorithm is used to resolve optimization levels because of its efficiency in solving optimization problems in a very few iterations and its speedy convergence. The various results achieved demonstrate highest DISCOM profit and also lowest generation cost of MG. Statistical assessments reinforce RIME optimization’s robust and efficient performance in resolving complex optimization problems.
