The Current Status and Experience of Renewable Energy Development in Portugal

Portugal has extensive expertise and decades of practice in the field of renewable energy grid-connected technology. In particular, in the past ten years, much more rich experiences have been gained in large-scale grid-connected operation and management of renewable energy. The level of renewable energy operation control is very high in Portugal. Recently, the Portuguese power grid has experienced three times of 100% renewable energy (hydropower, biomass, wind power, PV power, etc.) to support the continuous operation of the national power load for several days. The successful consumption of large-scale renewable energy in power systems is a systematic project. It relies on energy planning, national transmission network planning, operational and control technologies, and market mechanisms. The current status of Portugal's renewable energy development and its related experience are analyzed in this paper.
