A Cyber-Physical Security Analysis of Synchronous-Islanded Microgrid Operation

Cyber-security research in the field of smart grids is often performed with a focus on either the power and control domain or the Information and Communications Technology (ICT) domain. The characteristics of the power equipment or ICT domain are commonly not collectively considered. This work provides an analysis of the physical effects of cyber-attacks on microgrids – a smart grid construct that allows continued power supply when disconnected from a main grid. Different types of microgrid operations are explained (connected, islanded and synchronous-islanding) and potential cyber-attacks and their physical effects are analyzed. A testbed that is based on physical power and ICT equipment is presented to validate the results in both the physical and ICT domain.

The Impact of the Recent Economic Recession on the operation of the NEC Contract in Northern Ireland

In May 2006, the NEC contract was introduced as the preferred contract for Northern Ireland public sector works. This was subsequently followed by the 2007 economic crash and ensuing recession, which continues to affect the Northern Ireland Construction Industry, to a greater extent than the remainder of the United Kingdom (UK). However, use of the NEC contract has increased during this period, particularly in the public sector. There has been debate in the literature regarding the impact of the NEC contract on adversarial behaviour, but little consideration of the impact of external economic factors on the use of the NEC contract. Using a sequential mixed method approach, the study aims to fill this gap in knowledge, through examination of the impact the economic downturn has had on the operation of the NEC contract in Northern Ireland. Qualitative and quantitative findings show that the demands placed by the NEC contract, and the effects of the economic recession, have exerted opposing forces contract implementation, thus hindering its execution. The findings can lead to a deeper understanding, in the context of both industry and academia, of situations where a lack of resources may negatively impact the operation of the NEC contract.
