Utilizing renewable energy including photovoltaic (PV) power generation is raising expectations as a key to realizing a sustainable and affluent low-carbon society.However, there is an issue with effectively using such energy in accordance with demand because the amount of energy generated may vary greatly with unpredictable changes in the weather.While PV power generation has a characteristic suited for peak power reduction—more energy is output in the daytime and during the summer when energy demand increases—it is necessary to appropriately deal with the hard-to-predict output variations in order to enhance the peak power reduction effect.This paper presents a technology for optimal operation planning for storage batteries that has been developed for resolving this issue and verification results based on the results of operating a demonstration system built in Fujitsu's Kawasaki Research amp; Manufacturing Facilities.
