Abstract: The role of the battery energy storage system (BESS) has become essential in modern power systems. Among various types of BESS, NAS (Sodium and Sulfur) battery is one of the most promising products. NAS battery system is a commercial product implemented widely in Japan. A practical strategy and planning of NAS battery operation is proposed in this paper. In Planning, a load forecast using past cases is introduction. In strategy, two important parameters are evaluated to get a satisfactory performance of the load following operation of NAS battery. The first one is the amount of reserve (margin) and the second one is the trigger of release. The amount of margin is defined as a percentage of gcharged battery energyh. A predetermined threshold is used to control the battery energy use in this paper. By a series of computational simulations, it is verified that the load-following operation introduced by this strategy yields flexible and cost-benefit effectiveness.
