“…Although still in the infant stages, the concept of SoS has managed to achieve widespread acclaim. Being restricted to defense and information technology (IT) at one point of time, SoS has now entered a plethora of domains (Henshaw et al, 2013;Jamshidi, 2008a). Many definitions have been proposed in the literature for SoS, the more descriptive one being 'systems of systems are large-scale integrated systems that are heterogeneous and independently operable on their own, but are networked together for a common goal' (Jamshidi, 2008b), where the goal is cost-effectiveness, robustness and performance.…”

The microgrid has made its mark in distributed generation and has attracted widespread research. However, microgrid is a complex system which needs to be viewed from an intelligent system of systems perspective. In this paper, a network control system of systems is designed for the islanded microgrid system consisting of three distributed generation units as three subsystems supplying a load. The controller stabilises the microgrid system in the presence of communication infractions such as packet dropouts and delays. Simulation results are included to elucidate the effectiveness of the proposed control strategy.

Economic challenges, technological advancements, and environmental impacts are now demanding distributed generation (DG) in the place of the conventional centralized generation [18]. Power operation companies are now confronted with unprecedented difficulties in terms of meeting the load requirements, consumer satisfaction, and environmental considerations. Thus, DG has received good attention because of its potential to alleviate pressure from the main transmission system by supplying a few local loads [1]. The waste heat generated from the fuel to electricity conversion is exploited by the distributed generation system (DGS) with the help of microturbines, reciprocating engines, and fuel cells to provide heat and power to the customers. Adding to the system distributed energy sources (DES) like photovoltaic (PV) panels, wind turbines (WTs), energy storage devices such as batteries and capacitors, generators extracting energy from other renewable and controllable loads can provide momentous contributions to future energy generation and distribution. Another noteworthy feature is that the carbon emission is reduced to a large extent satisfying the commitment of many nations concerning decrease of carbon footprints [8]. However, the DG faces technical issues regarding its connection to the intermittent renewable generation and feeble areas of the distribution network. Further, owing to the distinct behavior of the DG unlike the conventional load, alteration in power flow results in problems. To counter the irregular behavior and increasing penetration of the DG, the microgrid (MG) was introduced.The concept of MG has received considerable attention owing to its potential to serve as an alternate power source, utilizing unconventional sources and supplying the most critical loads of the main grid in case of a network failure. MGs are low voltage networks or distributed energy systems which provide heat and power to a particular area by employing generators and loads. They have the ability to operate independently and isolate themselves from the main grid in case of a fault [4,5,26]. If proper control techniques are implemented, they may improve the reliability of electrical energy supply. MG comprises of microturbines, WTs, fuel cells, PV

“…While ergonomics practitioners are skilled in systems ergonomics, there is a requirement for extension of this into systems of systems ergonomics, since CPSs have extra characteristics not evident at the systems level (see section 3.1 above), such as the interoperability issues consequent upon linking independent systems together (Maier 1998, Dahmann and Baldwin 2008, Jamshidi 2009b, Firesmith 2010, Barot, Henson et al 2012, Henshaw, Barot et al 2013. A major consideration in the CPS and systems of systems environment is emergent behaviour, frequently intended and beneficial, but also unexpected, unpredictable and detrimental.…”

Global drivers, sustainable manufacturing and systems ergonomics

This paper briefly explores the expected impact of the 'Global Drivers' (such as population demographics, food security; energy security; community security and safety), and the role of sustainability engineering in mitigating the potential effects of these Global Drivers. The message of the paper is that sustainability requires a significant input from Ergonomics/ Human Factors, but the profession needs some expansion in its thinking in order to make this contribution.Creating a future sustainable world in which people experience an acceptable way of life will not happen without a large input from manufacturing industry into all the Global Drivers, both in delivering products that meet sustainability criteria (such as durability, reliability, minimised material requirement and low energy consumption), and in developing sustainable processes to deliver products for sustainability (such as minimum waste, minimum emissions and low energy consumption). Appropriate changes are already being implemented in manufacturing industry, including new business models, new jobs and new skills.Considerable high-level planning around the world is in progress and is bringing about these changes; for example, there is the US 'Advanced Manufacturing National Program' (AMNP)', the German 'Industrie 4.0' plan, the French plan 'la nouvelle France industrielle' and the UK Foresight publications on the 'Future of Manufacturing'.All of these activities recognise the central part that humans will continue to play in the new manufacturing paradigms; however, they do not discuss many of the issues that systems ergonomics professionals acknowledge. This paper discusses a number of these issues, highlighting the need for some new thinking and knowledge capture by systems ergonomics professionals. Among these are ethical issues, job content and skills issues.Towards the end, there is a summary of knowledge extensions considered necessary in order that Systems Ergonomists can be fully effective in this new environment, together with suggestions for the means to acquire and disseminate the knowledge extensions.
