Professor Tim Green is Co-Director of the Energy Futures Lab, an institute that promotes and stimulates multi-disciplinary research, education and translation in energy at Imperial College London. His research is in formulating the future form of energy systems to support zero carbon futures and in particular the exploitation of the flexibility of power electronics to achieve high penetrations of variable renewable energy. He has researched Soft-Open-Points for enhanced operation of distribution networks, High Voltage DC for international interconnection and the stability of inverter-dominated grids and microgrids. He is a fellow of the Royal Academy of Engineering and IEEE.

Keynote: Solutions for stability of electricity grids with high penetration of inverter-based resources

The replacement of electro-mechanical machines by inverter-based resources (IBR) is fundamentally changing the dynamics and stability properties of grids, and further, the growth of small-scale resources raises the curse of dimensionality. How should theories and tools for stability analysis evolve to tackle these new properties and new dimensionality? This talk reviews recent progresses in stability analysis techniques including review of synchronisation across traditional generators, grid-following inverters and grid forming inverters and black-box, grey-box and white-box views of participation of individual IBR in modes of the system. Under pinning this are modelling techniques employing impedance spectrum models and new techniques in order reduction. Together, these methods offer useful advances for simplification and interpretation of complex grids and have been combined into a toolchain for automated stability analysis of large-scale grids.

Keynote: Space Microgrids - NanoSats, Lunar Bases and Closed Ecosystems

This talk will begin by introducing the control of microgrids, the parallelisms with the human brain and the research for possible sources of inspiration in last frontiers of neuroscience. Then, control in electric power systems of satellites and space platforms will be presented, showing approaches that are extended from terrestrial microgrids and explaining the differences and challenges when it comes to apply them out in the space. Further, multi-microgrid systems will be discussed for moon craters in future lunar manmade bases. Finally, the extension from the hierarchical control of microgrids to bioastronautics in the control of closed ecological systems to support with oxygen, water, and food to the astronauts and creating thus creating new ecosystems for the moon and future mars bases.

Keynote: From software to savings - using digitalisation to unlock energy efficiency and sustainability

Siemens globally supports their broad customer base to improve their productivity and journey towards, sustainably, achieving their net zero targets. However, businesses have many different constraints making every journey different, whether they are an SME or multinational. But thanks to Energy Solutions at Siemens, digital toolchains are providing insight, clarity and data allowing organisations to design tangible roadmaps to net zero. Siemens is collaborating with a number of progressive universities around the UK on digitally enhancing their facilities to sustainably deliver decarbonisation goals and reduce energy costs. One of the key enablers is the use of Siemens industrial software to create digital twins of the facilities and campus, which then incorporate our automated energy management systems to establish the best systems optimisations. As we spend 90% of our lives in buildings, it is important that these designed spaces can be realised for comfort, efficiency and safety, and that can be optimised in real-time to adapt to the conditions – this then has an impact on energy use, occupant density, facility design (storage, efficiency, safety in COVID-19 and heating and cooling).

Keynote: Distributed Parallel Optimization for a Large-Scale Aggregation of Prosumers

A novel scalable and privacy-preserving distributed parallel optimization that allows the participation of large-scale aggregation of prosumers with residential PV-battery systems in the market for the ancillary service (ASM) is proposed in this paper. To consider both reserve capacity and reserve energy, day-ahead and real-time stages in the ASM are considered. A method, based on hybrid Variable Neighbourhood Search (VNS) and distributed parallel optimization is designed for the day ahead and real-time optimization. Different distributed optimization methods are compared and designed, and a new distributed optimization method based on Linear Programming (LP) is designed that overcomes previous methods based on integer and Quadratic programming (QP). The proposed LP-based optimization can be easily coded up and implemented on microcontrollers and connected to a designed Internet of Things (IoT) based architecture. Both day-ahead and real-time proposed optimization methods, by allocating the computational effort among local resources, are highly scalable and fulfil the privacy of prosumers.

Keynote: Grid Edge Solutions for sector coupling between power and transport

Energy systems are currently undergoing several coincident paradigm shifts. Global megatrends of electrification, digitalization, and decentralization are reshaping how we plan, address, and operationalize for the energy needs of the next generations. Sector coupling, in particular between power and transport as mobility is increasingly powered by batteries, will create new opportunities and require new solutions spanning these sectors.

In electricity networks there is a massive concomitant trend towards adding large amounts of renewable and distributed energy resources (DERs) near the edge of the network. In other words, this means more renewables, more battery storage but also more flexible management of loads in the electrical distribution systems. Such a fundamental change in asset portfolios, and new ownership models such as prosumers, requires novel ways of managing the network, leading to the implementation of microgrid and microgrid-like grid edge solutions that locally combine DERs. It also leads to large numbers of these grid edge solutions and other DERs that are aggregated into virtual power plants. Increasingly affordable battery storage and solar generation are key technology drivers, but the benefits of these are unlocked by end-to-end digital solutions integrating real time control with cloud-based asset managing.

The electrification of the transport sector emphasizes the need for reliable, flexible, and resilient electricity supply. In my presentation I want to highlight how automation and storage play a key role in successful sector coupling, illustrated by smart charging concepts for commercial electric bus and fleet depots. The combination of intelligent energy management solutions for charging in depots together with battery energy storage can contribute towards reducing peak demand charges, avoiding overload conditions for the grid interface and also allow for integration of local renewable generation or the provision of network services.
