Comparative Architecture Analysis: Using Laminar Structure to Unify Multiple Grid Architectures

A great many architectures for various aspects of electric grids have been proposed over recent years and new ones continue to be suggested. Generally speaking, there is no means except ad hoc analysis by which one can reduce these architectures to some common basis, or extract common elements. This leads to confusion in choosing an architecture for implementation, as well as making it difficult to identify core product or platform opportunities with sufficient potential markets to encourage vendors to provide or develop them.
The discipline of Grid Architecture as defined for the US Department of Energy (DOE) in 2014 has multiple purposes. Among them are two that are relevant here:
• Providing rigorous bases for architectural structures
• Identifying common aspects of apparently divergent architectural structures
For the first of these, mathematical methods are applied where possible to provide the rigorous basis for structure. For the second, mapping of architectural structures to a canonical structure puts apparently disparate architectures onto a common basis. In the best case, these two methods coincide.
In this paper, Laminar Coordination structure serves as the rigorously defined common basis for analysis of several real and proposed grid architectures.
