The multi-agent system is emerging as an effecting tool for the realization of the smart power distribution system. The smart power distribution system comprises the different scattered entities such as grid supply, renewable generations, customers, etc. In this distributed system, with the use of information and communication technology (ICT) and control systems, multi-agent system can implement different control and management schemes. The renewable generations such as solar photovoltaic (PV), and wind, as well as electrical load are associated with uncertainties. In this chapter, different battery agents are designed to work for scattered distributed battery energy storage system (BESS). These battery agents decide the power exchange for charging and discharging of BESS in order to balance the power mismatch and cater uncertainties in the smart power distribution system. The LQR-based distributed robust optimal control schemes are designed for battery agents to achieve the objective of balancing the power mismatch in the presence of uncertainties. The proposed control schemes show that the effects of uncertainties in power distribution system, in terms of power and energy sharing, are distributed and catered by all energy storage devices as per their energy storing capacities.
