Rising levels of inverter-based resources (IBRs) create a need for new approaches to modelling for the power grid, for both operational and planning purposes. Examples of such shifts in modelling approaches are occurring for some regions of Australia’s National Electricity Market (NEM) power system, as the need to understand and address unknowns before events occur…

Customer-sited renewable resources offer tremendous promise for lowering costs, improving reliability, and reducing carbon footprint on the electric grid. But operators struggle to take advantage of the various forms of flexibility, having found it challenging to get multiple resources and increasingly complex systems to work well together. A distributed control environment, in which some assets…

A goal of competitive wholesale markets is to be efficient both in the short-run, by ensuring that resources are dispatched to minimize production costs while maintaining secure operations, and in the long-run, by ensuring that market prices help to coordinate investment in new generation or the orderly retirement of resources that are no longer competitive.…

Introduction China’s urbanization rate increased from 36% in 2000 to 60% in 2019. With the rapid growth of urbanization, the efficiency of the centralized energy supply is receiving increasing attention. It becomes more important to coordinate different energy sectors, i.e., electricity, heating, cooling, and gas systems to increase the overall energy efficiency. With the development…

Why have grid-forming inverters become a hot topic? High penetration of renewable energy, mainly from wind and photovoltaics (PV), has been associated with a major shift in power source connections. The shift has been from power sources being connected to the power systems directly using synchronous generators, to connections via solid state inverters, introducing inverter-based…
