BCTC’s experience towards a smarter grid - increasing limits and reliability with centralized intelligence Remedial Action Schemes

This paper presents the system perspective of BC Transmission Corporationpsilas (BCTC) strategy and experience with the EMS based Remedial Action Schemes (EMS-RAS) system. The automated centralized intelligence RAS has been successful since its implementation in 1994 in providing improvement in reliability and transfer limits. Three examples are provided to illustrate the EMS-RAS capability and flexibility with specific examples of transfer increases.
