IEC 61850-based Communication Specifications for Output Curtailment of Generators with Non-firm Connection Agreement

Abstract

This paper proposes the application of IEC 61850 standards to manage communications for output curtailment setpoints directed at generators with non-firm connection agreements. The unique requirements of such communications include managing schedules that span two days, updating setpoints in rapid cycles, and ensuring reliability amidst communication disruptions. To address these needs, the proposal outlines the use of logical nodes for scheduling. The efficacy of the proposed specifications has been confirmed through tests conducted on a prototype system.
