Abstract

Renewable energy generation in the All-Island of Ireland (AII) is set to increase by 2020 due to binding renewable energy targets. To achieve these targets, there will be periods of time when 75% of electricity will be generated mainly from onshore wind. Currently, the AII system can accommodate a 50% maximum permissible instantaneous level of wind generation. The system operators must make system wide wind curtailment decisions to ensure this level is not breached. Subsequently, the ability to limit wind curtailment using large scale energy storage such as pumped hydroelectric energy storage and compressed air energy storage (CAES) is increasingly being scrutinized as a viable option. Thus, the aims of this paper are to estimate the level of wind curtailment on the 2020 AII system for various scenarios including with and without CAES; assess and quantify the revenue loss due to wind curtailment using power systems simulation software PLEXOS
