Enhanced Economic Load Dispatch in Smart Grid Through Pelican Optimization Algorithm

The efficient management of Economic Load Dispatch (ELD) in microgrids is crucial for optimizing energy costs, maintaining grid stability, and integrating renewable energy sources. This paper proposes a method of enhancing the ELD in a multi-microgrid system using the Pelican Optimization Algorithm (POA), tested on IEEE-14 bus system. Here, the objective function includes reduction of line losses, optimization of cost efficiency and reserve generation, enhancement of grid stability, and maximization of power generation for achieving optimal ELD. Further performance of the proposed POA method for ELD enhancement is compared with Moth-Flame Optimization (MFO) and Particle Swarm Optimization (PSO). Additionally, POA provides enhanced operational stability with lower variability in power output and maintenance costs, making it a superior choice for optimizing microgrid operations. The results highlight that POA outperforms MFO, achieving a 45.4% reduction in power generation costs and a 56.3% increase in power output for certain units. Moreover, the comparative analysis underscores the superiority of POA in managing microgrid operations, offering a promising solution for future energy management challenges.
