The workstream covered topics related to maintaining transmission system reliability from the transmission owner or ISO/RTO perspective, including transmission operations tools and transmission planning assessments with active DERs.
The first task of the workstream was to support transmission operators through structured analysis to identify the main issues faced in operations with high DER market participation. The task reviewed the main functions carried out by transmission operators in real time operations and operations planning, identified how DER market participation could influence bulk system opera¬tions, and cataloged several options to integrate DER or mitigate adverse impacts for transmission operators. Overall, it represented a highly structured approach towards assessing the impact of DER aggregations.
