The Nested Hierarchy as a System Structure in a Changing Industry
Before introducing the notion of nested hierarchies, considered here as necessary for formulating operation and control in the changing electric power industry, we briefly describe the horizontal hierarchy structure typically found in existing power systems. Next, we introduce the concept of the nested hierarchy and its relation to the changes required in present system operation and control in order to accommodate competitive supply/demand energy transactions while still keeping the system together. Examples of some recently evolved industry structures are shown to be particular cases of the general nested hierarchy.
