In the quest for more resilient and efficient energy systems, researchers are turning to advanced technologies to optimize the management of decentralized energy solutions. A recent study published in the journal *Engineering Reports* (translated from the original title) sheds light on innovative approaches to enhance the performance of microgrids, particularly those integrated with renewable energy sources. The research, led by Subhasis Panda from the Department of Electrical Engineering at Siksha ‘O’ Anusandhan University in Bhubaneswar, India, focuses on the optimization of energy management systems (EMS) for grid-connected photovoltaic (PV)–battery systems using demand response (DR) techniques and particle swarm optimization (PSO).
As temperatures rise and power demands increase, microgrid failures have become more frequent, highlighting the need for effective energy management. Microgrids, especially those incorporating renewable energy sources, are gaining popularity as decentralized energy solutions. However, PV systems face challenges due to the intermittent nature of solar energy, necessitating energy storage solutions to maintain a stable power supply. Battery energy storage systems (BESS) play a crucial role in buffering power fluctuations and enhancing grid stability, enabling PV–battery hybrid microgrids to operate in both grid-connected and islanded modes.
Panda’s study aims to optimize the management of BESS within a solar-integrated microgrid over a 24-hour period to improve energy efficiency and cost-effectiveness. The research also explores the implementation of demand response techniques, such as peak clipping, valley filling, and load shifting, to further enhance grid stability and economic benefits. Using MATLAB for simulations, the study employs state flow study and linear programming methods.
The results are promising. “The energy management system using particle swarm optimization enhances the efficiency of EMS using linear programming,” Panda explains. Simulation results conducted using MATLAB R2023b indicate that PSO outperforms LP in minimizing daily electricity costs (up to 15.32% savings), stabilizing the state of charge (SoC), and reducing grid power fluctuations. These findings underscore the importance of advanced EMS in enhancing microgrid efficiency, particularly under variable weather conditions.
The implications for the energy sector are significant. By optimizing the charge and discharge cycles of BESS based on load requirements and implementing DR strategies, the proposed methods demonstrate substantial improvements in system performance and economic benefits. This research highlights the crucial role of energy management systems in enhancing the reliability and sustainability of microgrids, particularly in rural and underdeveloped areas.
As the energy landscape continues to evolve, the integration of advanced optimization techniques and demand response strategies will be pivotal in shaping the future of smart grids. Panda’s work not only provides valuable insights into the optimization of microgrid performance but also paves the way for more resilient and efficient energy systems. The findings published in *Engineering Reports* offer a glimpse into the potential of advanced EMS in transforming the energy sector, making it more adaptable and sustainable in the face of growing demands and environmental challenges.
