Inhalt:
The Multiple Power Quality Supply System as the Sendai microgrid is designed as an ideal power supply system that can simultaneously provide services with multiple power quality levels. The microgrid was developed by NTT Facilities and was installed on the campus of Tohoku Fukushi University in Sendai City, Japan. On March 11, 2011, a tsunami and large-scale earthquake such as Japan had never experienced before struck the Tohoku area and caused severe damage to many cities and towns. The devastating Great East Japan Earthquake hit the Tohoku district, inflicting catastrophic damage on the district’s energy supply system for a number of days. Despite the extreme devastation, the Sendai Microgrid continued supplying power and heat to customers, proving its effectiveness. This paper reports the behaviour of the Sendai microgrid during and after the Great East Japan Disaster.
