Impacts of bulk wind generation and waste-to-energy on the economic operation of the Puerto Rico Electric Power Authority system

The Puerto Rico Electric Power Authority (PREPA) supports an orderly development of the renewable energy potential on the islands. To attain this goal, PREPA is conducting science-based analytical studies and research to increase knowledge on these technologies. As part of this effort, PREPA commissioned the Electric Power Research Institute (EPRI) to assess the potential impacts that different penetration levels of waste-to-energy (WTE) and wind generation on PREPA power system operations. The study covered different technical and economic aspects of wind integration. This paper summarizes the impact of hourly wind power variability and wind generation forecast uncertainty on system operation cost The analytical approach and evaluation results are described.
