Abstract
The grid connected 100 kW PV and 345 kWh battery combined system introduced in 1998 at Shonan Institute of Technology has been investigated. The syste m, equipped with PV and large battery, has a peak cut function against the big surge in electric power consumption in summer as well as working as an emergency electric power source. The daily peak of power consumption during summer occurs at 2:00 p.m. This time does not coincide with the time of pe ak power generation. The use of the PV/battery combined peak cut function e ffectively cuts consumption by 7% during the peak consumption period. (C) 2 001 Elsevier Science B.V. All rights reserved.
