Pillar 1: System Operator Research and Peer Learning Accomplishments
G-PST/ESIG Webinar Series: Going the Distance: Moving AC Power from Large Inverter-Based Generation Pockets to Load Centers
Featured Speakers: Nick Miller, Principal, HickoryLedge LLC & Matthew Richwine, Founding Partner, Telos Energy
Webinar Abstract: Getting the power from large areas of high-quality wind and solar resources across AC transmission to load centers is one of the most pressing and practical challenges facing major interconnections today. This webinar covers the stability challenges associated with long-distance, high-voltage transmission by examining the performance of emerging grid-forming inverter technology relative to grid-following inverter technology and synchronous machine technology and the impact of non-wires transmission system reinforcements.
G-PST/ESIG Webinar Series: Developing an Engineering Framework to Support Australia’s Energy Transition
Featured Speaker: Christian Schaefer, General Manager, Energy Systems Engineering, Australian Energy Market Operator (AEMO)
Australia is a world leader in the rate of adoption of renewable energy. This webinar will describe AEMO’s proposal for an Engineering Framework to provide an integrated roadmap for the National Electricity Market’s energy transition.
The Engineering Framework seeks to provide an up-to-date foundation regarding emerging power system design and operability needs, as a complement to existing work being progressed across industry, recognizing that in managing the energy transition, no one organization has all the answers. Hence, the Engineering Framework is intended to help stakeholders stay informed of the changing technical needs of the power system, the work underway to meet these changing needs, how the different pieces fit together, and how they can engage on topics of interest. This framework is also needed to structure industry discussions around the prioritization of future work, so that the most urgent issues are addressed first.
The Engineering Framework is structured around the three pillars of: system integration, system attributes and system operability, and describes a number focus areas within these.
G-PST/ESIG Webinar Series: Frequency Control in a 100% Inverter Based Grid
Featured Speaker: Deepak Ramasubramanian, Senior Engineer Scientist, EPRI
The changing resource mix of the bulk power system, particularly the increasing deployment of wind power and solar PV, has resulted in an increasing portion of the resource mix being asynchronously connected through inverters – Inverter Based Resources (IBRs). These resources behave differently than traditional synchronous resources, which has necessitated investigation into viable alternate control schemes for use during operation of the system. A major theme of alternate schemes proposed in research has been on ensuring that these IBRs conform to the operational norms and limits that are presently followed. However as a faster response can be obtained from IBRs, this webinar will first pose the question of whether there is really a need to make IBRs conform to a slower operational paradigm which reflects synchronous machine operation. Or can the fast response characteristics of an IBR be leveraged to obtain superior frequency control?
G-PST Research Agenda Group Maps Out the Research Frontier for System Operators
Representatives from leading global technical institutes and the G-PST Founding System Operators are actively defining near-term applied research priorities and programs to support system operators in achieving very high penetrations (i.e., >80%) of inverter-based variable renewable energy resources on their power systems over the next decade. This process is systematically mapping out the state-of-the-art in research, industry and practitioner communities around the world, and identifying key knowledge gaps that can be filled by cutting-edge research activities in the priority areas. It will then develop research proposals and seek to secure support from national research program managers for collaborative research with the Founding System Operators. Ultimately, this research agenda will be pursued by all participating system operators and technical institutes in the G-PST Consortium, with insights efficiently disseminated for broad adaptation and application.
Pillar 2: System Operator and Technical Support Accomplishments
Designing Control Rooms to Support High Penetrations of Variable Renewable Energy
Featured Speaker: Evy Haryadi, PLN Indonesia; Adrian Kelly, EPRI Europe; Sadie Cox, NREL; Hongming Zhang, NREL
Webinar Abstract: As power systems continue to evolve, control rooms and other operational measures must evolve alongside them. The Global Power System Transformation (G-PST) Consortium’s Pillar 2 lead organization, the National Renewable Energy Laboratory (NREL), presented this webinar examining good practices for designing power system control rooms with high penetrations of variable renewable energy in mind. Presentations focused on sharing experiences and lessons that support cutting-edge upgrades to control rooms as countries integrate greater shares of renewables into their power sectors. The Electric Power Research Institute (EPRI) shared learnings from their experience leading work on developing control rooms of the future and PLN Indonesia highlighted plans for upgrading their Java-Bali grid control room.
