In recent years, South Korea accelerated its deployment of renewable energy and assigned Jeju, its largest island, as a testing ground for smart grid concepts like battery storage and demand response (for example, using electric vehicles). In a project funded by A1 Engineering, Seita, together with A1 Engineering, will develop a balancing valorisation platform for Jeju: a multi-user web application for scheduling balancing actions from a diverse set of assets on the island. The platform allows energy companies and asset owners to monitor power consumption and production as well as relevant price data. In addition, the platform uses algorithms for machine learning and control strategies to assist human operators with forecasts and decision-making.
