    This paper considers the superior operating control function and instantaneous discharging characteristics of NAS battery systems, and proposes a method for determining installation planning and operating control schemes of NAS battery systems for suppressing line overload phenomena. In the planning stage, a target contingency is identified, and an optimal allocation and capacity of NAS battery systems and an amount of generation changes are determined for the contingency. In the operation stage, the control strategy of the NAS battery system is determined. Simulations are carried out for verifying the validity of the proposed method using the IEEJ I-machine V-system model and an example 2-machine 16-bus system model.
