要約(英語): In Kyushu area, renewable energy, mainly consists of PV, has been introduced rapidly. Therefore, as for dispatching operation, a risk that renewable energy should be suppressed because of restrictions of thermal plants' minimum operation is growing faster than ever especially during light demand daytime. To avoid this risk, in March 2016 we constructed Buzen Battery Substation and installed a large scale battery system (output: 50MW × 6 hours, capacity: 300MWh) featured NAS batteries. We implemented verification study by operating NAS battery system's function similar to a pumped storage plants aiming to avoid maximally 300MWh suppression of renewable energy per day by establishing its operation method to improve the energy balance. As a result, we verified that NAS battery system has ability to charge/discharge 300MWh energy safely and to control the grid voltage by changing reactive power output.
