Resiliency in Flexible Electricity Grids

The issue of resiliency in the electricity grids has attracted attention in the USA with recent devastating impacts of catastrophic weather storms such as Harvey in 2017, Supestorm Sandy in 2012, and Katrina in 2005. While such rare events create huge financial losses, as well loss of life and infrastructure/property, it is also noticed that over $200billion are lost in the USA alone each year to outages due to the impact of the seasonal severe weather events such as high winds, heavy rain, ice storms, draughts/fires, etc. The challenge is to decide how to mitigate such events and their impact on loss of the electricity lifeline for all the electric energy consumers. The recent reports issued by the Executive Office of the US President in Dec 2016, the US National Academies in 2017 and the IEEE Proceedings in 2017 offer a number of issues to be considered, but it still remains an open question what conceptual and technological solutions are most effective and warrant future investments.

The focus of this talk is on the holistic view of the electric grid resiliency that takes into account the operations, planning, asset and outage management services of the traditional utility company, as well as non-traditional services and resources across wide range of distributed producer and consumer (Prosumer) sites. This notion encourages the developments of the Flexible Electricity Grids (FLEG), and also suggests that special attention should be placed on the predictive, machine learning techniques not traditionally used today that will allow time to engage various effective mitigation approaches. The talk focuses not only on the preemptive measures (mitigation) but also on the reactive measures (restoration), which work hand-in-hand in a holistic approach to the resiliency risk management.

The crucial Role of Distribution System Operators for the Transition of Energy Systems

The energy market is in transition, triggered by the European climate action targets set for 2030. DSOs, as the operators of the distribution systems, will connect and integrate a constantly growing number of distributed generation, while simultaneously engage customers and enable their secure integration as prosumers. The transition of Energy Systems is based on the digital advances (smart meters and network automation), therefore DSOs are becoming increasingly data centric companies responsible for managing their grids more actively. The presentation will outline the challenges and opportunities faced by DSOs in Europe to achieve this transition focusing on new technologies and innovative solutions.

Shipboard and Seaport Microgrids: also going to DC?

The development of electrical power systems in maritime applications like ships, ferries, vessels and seaports are calling for more advanced technologies integrating power electronics, energy storage devices, control and supervisory systems and onboard communications. The challenges of those electrical isolated systems are being solved in other terrestrial microgrid applications, so that many ideas and concepts can be shifted and adapted in order to reduce the fuel consumption in marine applications. Compared with terrestrial microgrid applications, the concept of AC and DC microgrids are presented in this Keynote. Several relevant technologies and standards are provided to ensure adequate power quality and fuel efficiency in ship systems. Many real projects under development in full and hybrid electrical ships and ferries will be presented.
