The topological (graph) structure of complex networks often provides valuable information about the performance and vulnerability of the network. However, there are multiple ways to represent a given network as a graph. Electric power transmission and distribution networks have a topological structure that is straightforward to represent and analyze as a… (More)

derive a measure of " electrical centrality " for AC power networks, which describes the structure of the network as a function of its electrical topology rather than its physical topology. We compare our centrality measure to conventional measures of network structure using the IEEE 300-bus network. We find that when measured electrically, power networks… (More)

Numerous recent reports have assessed the adequacy of current generating capacity to meet the growing electricity demand from Plug-in Hybrid Electric Vehicles (PHEVs) and the potential for using these vehicles to provide grid support (Vehicle to Grid, V2G) services. However, little has been written on how these new loads will affect the medium and… (More)

Numerous recent papers have found important relationships between network structure and risks within networks. These results indicate that network structure can dramatically affect the relative effectiveness of risk identification and mitigation methods. With this in mind this paper provides a comparative analysis of the topological and electrical structure… (More)

This paper describes results from the analysis of two approaches to blackout risk analysis in electric power systems. In the first analysis, we compare two topological (graph-theoretic) methods for finding vulnerable locations in a power grid, to a simple model of cascading outage. This comparison indicates that topological models can lead to misleading… (More)

Conventional measures of market structure used by economists, such as the Herfindahl Hirschman Index (HHI), give a misleading picture of the competitiveness of electric power markets, since these metrics do not consider the special properties of electricity as a commodity. The notion of a " pivotal supplier " is better-suited to the electric power industry;… (More)

Braess' Paradox describes a situation in which constructing a Wheatstone bridge causes or worsens congestion in a network, thus increasing the cost to users. While this behavior has been extensively studied in other network industries, its implications for power systems have not. The steady-state conditions under which Braess' Paradox holds in a simple… (More)
