Intermittent renewable energy sources require the large-scale battery energy storage system for ensuring grid-wide frequency stability. As a kind of the smart grid in Japanese context, we have proposed a ubiquitous power grid concept [1]. Total battery capacity could be optimized by coordinating the blade pitch angle control of wind power generation [2], the heat pump water heater [3], and the battery energy storage system [4] as coordinating to the conventional thermal power generation.

Because of advanced lithium battery and hybrid electric vehicle technology, large amount of next-generation vehicles including plug-in hybrid electric vehicle (PHEV) and electric vehicle (EV) are expected in Japan. Therefore, there is a large

Abstract- Penetrating large amount of renewable energy sources into power system, battery energy storage performs an important role for smoothing their natural intermittency, ensuring grid-wide frequency stability, and suppressing voltage rise caused by reverse power flow. The ubiquitous power grid is one of the concepts as a smart grid in Japanese context, where the total battery capacity can be optimized by coordinating renewable energy sources, controllable distributed generators, and controllable loads on demand side, for example, heat pump based water heater with heat storage, and plug-in hybrid vehicle or electric vehicle with onboard battery, and so on. These controllable devices behave as an autonomous distributed smart storage by charging or discharging against the power system frequency measurement as paying attention to user convenience. In this paper, effects of the autonomous distributed smart storage on bulk power systems are investigated thorough a load frequency control simulation.
