The availability of sampled values in IEC61850 combined with the ability to create SV nets across a wide area network allow the emergence of better wide area protection and multiple zone protection and control when secondary communication networks and primary electrical networks are integrated.
Leveraging the advantages of new protocols and packet based networks in a secure manner requires operational wide area networks with a focus on serving the electrical circuit not extending the enterprise paradigms in to the grid.

Routing has been absent in utility networks since communications entered the utility sphere to assist with SCADA and high speed relaying. Leveraging the advantage of packet communications to advance inter-substation communications doesn't require adding the security vulnerabilities of routing to the operational network.
Packet networks can also lower cost and the right packet network can save you over 40% CAPEX&OPEX over the wrong packet network while having clear security advantages.

Wide Area Architectures should consider full integration from Network System Management through primary electrical system as the "soft" data becomes more central to protection, automation and control.

I have worked on initial recommendations to emerging Network System Management standards and have authored and advanced Operational Wide Area Network architectures that support advancing PAC in the inter-substation sphere.

My interest is in taking packet communications between substation fences to advance the opportunities for PAC and packet networks to improve grid operations and efficiency.
