Agents are intelligent entities that act flexibly and autonomously and make wise decisions based on their intelligence and experience. A multi-agent system (MAS) contains multiple

intelligent

and interconnected collaborating agents for solving a problem beyond the ability of a single agent. A smart grid (SG) combines advanced intelligent systems

control techniques

and sensing methods with an existing utility power network. For controlling smart grids

various control systems with different architectures have already been developed. MAS-based control of power system operations has been shown to overcome the limitations of time required for analysis

relaying

and protection; transmission switching; communication protocols; and management of plant control. These systems provide an alternative for fast and accurate power network control. This paper provides a comprehensive overview of MASs used for the control of smart grids. The paper provides a wide-spectrum view of the status of smart grids

MAS-based control techniques and their implementation for the control of smart grids. Use of MASs in the control of various aspects of smart grids—including the management of energy
