Among these\, there are 37 inhabit ed islands where 1.46 million people reside.\n\nOkinawa Electric Power Com pany (OEPC) is a vertically integrated electric utility company engaged in all generation\, transmissions\, and distribution. The OEPC supplies elec tricity to all inhabited islands in Okinawa Prefecture. The prefecture has 11 independent power systems\, and due to the small scale of the island g rids other than the main island of Okinawa\, diesel power generation serve s as the primary source.\n\nThe OEPC has been forward-thinking in integrat ing solar and wind from the perspectives of climate change countermeasures and fuel cost reduction on the islands. However\, on small grids\, the wi despread integration of intermittent renewable resources such as solar and wind power can pose technical challenges regarding energy balance\, subse quently affecting grid frequency. To cope with this\, the company has focu sed on developing battery control technology to stabilize grid frequency b y mitigating solar and wind power fluctuations.\n\nMoreover\, as renewable energy increases\, diesel units face operational challenges\, with decrea sed output levels reducing negative headroom and necessitating corrective action through suppressing renewable energy output. As a substitute for di esel units\, while maintaining grid support capability\, OEPC has develope d a motor-driven generator powered by renewable-charged batteries\, known as an MG set. The MG set comprises generators\, AC induction motors\, and batteries\, addressing the negative headroom issue. Additionally\, the MG set allows for battery charging during periods of excess electric supply\, particularly when operating in regenerative charging mode. In 2020\, on H ateruma Island\, all diesel generators were provisionally stopped\, and th is grid\, alongside wind power\, MG sets\, and batteries\, achieved a 100% renewable energy supply for around ten continuous days.\n\nThis webinar s howcases two demonstration projects: 1) a Grid stabilization project with advanced battery controls on Miyako Island and 2) a 100% renewable energy supply project using the MG set on Hateruma Island.\n\nCo-sponsored by: Un iversity of California Riverside\n\nSpeaker(s): Mr. Yusuke Kuniba\, \n\nVi rtual: https://events.vtools.ieee.org/m/408947 LOCATION:Virtual: https://events.vtools.ieee.org/m/408947 ORGANIZER:mail@maxcherubin.com SEQUENCE:20 SUMMARY:Overview of Demonstration Project Aimed at Harnessing Renewable Ene rgy on Remote Islands URL;VALUE=URI:https://events.vtools.ieee.org/m/408947 X-ALT-DESC:Description: <br /><p>Okinawa Prefecture is located at the south ernmost tip of the Japanese archipelago\, comprising a vast expanse of sea spanning 1\,000 kilometers east to west and 400 kilometers north to south \, consisting of approximately 160 islands of various sizes.
