 Electricity demand has increased significantly in recent years due to industrialization and the transition to a smart grid system. To meet this growing demand, microgrids, renewable energy sources, plug-in electric vehicles, and energy storage systems have been introduced. These changes require the adaptation of existing electrical power systems to ensure reliable and efficient operation. Demand side management, DSM, programs are being implemented to address these challenges and improve the performance of electrical power systems. This paper reviews the current state of DSM initiatives, techniques, impacts, and recent developments. It also identifies potential benefits of DSM and provides directions for future work.
