The smart grid is one of the most significant applications of the next-generation communication networks, i.e. 5G/LTE, SD-WAN. MPLS, Fibre networks and IoT etc. As information and communication technologies (ICT) along with Cloud integration developed and applied in traditional power systems, the need for improvement in smart grid cyber-physical-systems (CPS) is increasing exponentially. Smart grid systems are critical infrastructures, also they have complex architectures and include critical end-node devices for real-time data monitoring.

Any malfunction in these critical infrastructures can lead to national security deficits, disruption of public services, and loss of life or large-scale economic damage when the confidentiality, integrity, or availability of the communication is broken down. These huge systems may be vulnerable to cyber-attacks. Therefore, there is a lot of research effort to enhance smart grid security in industry, government, and academia.

This theme focuses on next-generation communication frameworks, cyber-attacks, and provide in-depth knowledge of security and privacy in smart grids. Particularly, we concentrate on the discussion and examination of network vulnerabilities, resilience, attack countermeasures, and security requirements. We aim to supply a deep understanding of cybersecurity vulnerabilities and solutions and give a guide on future research directions for cyber-security in smart grid applications.

Reliable condition monitoring, proper diagnostics and accurate interpretation could help reduce the rate of ageing, improve operations and network optimisation, enable an accurate assessment of the overall integrity of the network and its assets, and minimise the risk of unexpected failures. Sensing technologies and systems play a strong role in fulfilling this need.

This theme develops novel sensors, as well as characterising a variety of sensor technologies that could be applied within the electricity business, and analyses methods and systems to make better use of data.

Future electricity networks will be capable of incorporating widespread energy generation, storage facilities and ‘smart grid’ solutions. From a protection perspective, networks will be subject to changing and variable fault levels. There will also be changes to the topology of networks and markedly different system behaviour, particularly during network faults. Coordination of network protection, and between network protection and the protection of distributed energy resources (including energy storage) both represent major challenges that need addressing through research, development and demonstration.

This theme investigates the protection and control of future networks, covering networks that are both incrementally and radically different from those of today, through a variety of means.

Power-electronic based technology is increasingly being adopted in power networks as FACTS (Flexible Alternating Current Transmission System) and HVDC devices to redirect power flow, control voltage, provide fast fault-current limiting as well as providing a grid interface for distributed energy resources such as solar, wind, energy storage and electric vehicles.

This core research theme looks at the grid integration and operational aspects of these technologies to optimise network operation by providing ancillary services and deferring reinforcement as well as the interplay of these technologies for a future smarter grid. The work is delivered under this theme in the form of testing, demonstration and simulation.

As such, the key words for this theme are ancillary services, microgrids, power quality, energy storage, electric vehicles, solar, wind, FACTS and HVDC.

Significant advancements towards a low carbon economy require the integration of clean and renewable forms of energy sources on the electricity networks. Future electricity networks need to be capable of incorporating widespread energy generation, storage facilities and “smart grid” solutions. These developments mean today’s networks will be increasingly subject to change with increasingly variable load levels, changes to the network topology and operation, and different types of end-user.

Power networks are subjected to a range of new influences and will be exposed to numerous innovative or novel technologies, products or operating paradigms that are evolving as part of future power systems.

Network and Demand Side Management (NDSM) solutions can assist in these anticipated future network scenarios by peak shifting electrical loads or redistributing unbalanced loads between phases. This activity and its evolution is the key focus of the Network and Demand Side Management theme.

Power generation, transmission and distribution is changing. The future includes a greater proportion of distributed generation and significant renewable sources which place new stresses on equipment and the systems that connect them. In addition, power industry infrastructure is ageing and there is a continual drive to optimise the utilisation of existing infrastructure, thus avoiding significant new capital investment. As such, the current asset base needs to operate safely, reliably and affordably, while minimising the risks and the impacts on the network of the new sources and load profiles.

Asset Management is critically important to make the most effective spend decisions. Operating power industry assets to their maximum useful lives while increasing the reliability of the operation and reducing the risks and the costs, is the ultimate aim.

In this context the asset management theme of research concentrates on the development of methodologies for assessing asset condition and estimation of the risk of failure through state of the art models, optimisation of maintenance practices, development cost analysis modules and investigation into decision-making practices.
