DER Flexibility

25 November 2020 | 12:00 – 2:00pm

Professor Pierluigi Mancarella
Veski Innovation Fellow, University of Melbourne

Abstract:

The aim of this tutorial is to present the main techno-economic concepts about provision of power system flexibility, reliability and resilience from distributed energy resources (DER).
Specific topics that will be covered include:

  • Modelling of DER for flexibility study purposes, including different types of distributed/embedded generators (e.g., photovoltaic, gas, diesel, and combined heat and power generators), storage (e.g., batteries, electric vehicles, thermal storage), and demand response (e.g., smart appliances, building-to-grid flexibility, hydrogen electrolyzers) resources;
  • DER aggregation modelling and orchestration under different concepts such as power nodes, virtual power plants, community energy systems, and microgrids;
  • Techno-economic characterization of the flexibility of individual DER and DER aggregations, with consideration of different metrics;
  • Generalization of DER to the emerging concept of distributed multi-energy systems (which also entail interaction with other energy vectors such as heat, cooling, hydrogen, etc.) and modelling of multi-energy flexibility via the recently proposed concept of multi-energy node;
  • Use of DER flexibility to provide market, security and reliability services, to support both system operation (e.g., energy arbitrage, frequency control ancillary services, fast frequency response, reactive power and voltage support) and planning (e.g., DER contribution to supply and network adequacy and capacity markets, displacement of network asset, firm-up of renewables and capacity credit assessment);
  • Use of DER flexibility to provide resilience services to deal with extreme, high-impact low-probability, events (again for both operation and planning);
  • Modelling and assessment of DER in the interaction with distribution system operators and at the interface with transmission system operation;
  • Discussion of technical, commercial and regulatory barriers to DER widespread adoption;
  • Case studies from a number of recent projects in Australia, UK, Europe, Malaysia and Chile.

A full list of relevant references and toolboxes will also be provided.
