Smart grids are an innovative energy infrastructure that utilizes information and communication technologies to manage energy production, transmission, and consumption more efficiently and sustainably. Designed to overcome the limitations of traditional energy grids and enable more dynamic and flexible energy management, smart grids employ advanced sensors, communication networks, and computing technologies to provide real-time monitoring, intelligent planning, and optimal management.

Smart grids are electricity network infrastructures that integrate information and communication technologies to monitor, manage, and optimize energy systems. Compared to conventional grids, smart grids have a more dynamic structure. They enable bidirectional flow, allowing both electricity and data transmission. This structure enhances operations, data transmission, security assessments, distribution decisions, and automated control systems within the grid. The use of smart grids ensures that energy production and distribution become more efficient, secure, and sustainable.
