The electricity sector worldwide is facing considerable pressure arising out of climate change issues, depletion of fossil fuels and geo-political issues around the location of remaining fossil fuel reserves. Electricity systems are also facing technical issues of bi-directional power flows, increasing long-distance power flows and a growing contribution from fluctuating generation sources. There is a concern that these systems are vulnerable. Investigation of vulnerability has focussed on shocks to the system associated with weather risks, equipment failure, supply (fuel) failure and price shocks, and analysis has been primarily based on financial measures such as the value of lost load.As the UK electricity system makes the transition to a low carbon future, it is unclear what this new future will look like. Transition pathways research using a multi-level perspective has identified a general picture of the drivers in future systems architecture. In such futures, vulnerability becomes multi-dimensional, and security becomes a more complex issue than that of supply of fossil fuels. These issues are not specific to the UK. Electricity systems across the globe face the same issues of multi-dimensional vulnerability and complexity of security. There are also issues around governance of energy, particularly for those scenarios that involve a significant proportion of energy needs being met locally.Research into the transition to a low carbon electricity system has, to date, been primarily focussed on the national scale in the UK. The aim of this work is a critical analysis into the 2050 pathway scenarios for the UK with respect to their impact locally on the distribution network in a case study urban area in the North East of England. The case study shall examine the proposed national low carbon scenarios, what this means in domestic and nondomestic buildings for the case study area, and the nature of the stress on the electricity distribution system which may result from the expected growth in electrical load. The significance of these findings shall then be discussed with respect to transitions and local governance.

“…A number of atomic models have been developed to represent both EI and II logical components, as identified in the previous Section, and their interactions in presence of malfunctions affecting one or both infrastructures. Such atomic models, implemented through the Stochastic Activity Networks (SAN) formalism, have been already presented in previously published papers (e.g., (Chiaradonna, Lollini & Di Giandomenico, 2007) and (Chiaradonna, Di Giandomenico & Lollini, 2011)). Therefore, we shortly recall them in this chapter, but without details.…”

“…While we basically maintained the above recalled models in the current EPS modelling framework, we extended the models related to the II infrastructure for what concerns the protocols addressed by the scenario to apply the emergency plan (arming requests) and the severity of the attacks to the DSO net, in particular all the models associated to the last two sets of submodels listed above have been modified with respect to the one proposed in (Chiaradonna, Di Giandomenico & Lollini, 2011), to appropriately take into account the reference scenario.…”

“…In this chapter we build on the model of EPS presented in (Chiaradonna, Di Giandomenico & Lollini, 2011), which defines a set of stochastic models representing in a rather faithful way (yet abstract enough to be tractable) both the electrical infrastructure evolution in presence of failures, and the control actions activated by the control system (both locally and at a higher level in the control hierarchy). The model is here enriched with a set of submodels that represent a cyber attack.…”

“…In the context of CRUTIAL, an innovative, modular EPS modelling approach, that considers separately the two constituting infrastructures but takes into account their interdependencies and allows to assess the impact of reciprocal failures, has been developed (Chiaradonna, Di Giandomenico & Lollini, 2011).…”
