An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation (CIG), include the variable renewable energy generators (wind, solar) and battery storage power stations. [1]
Large penetration of the inverter-based resources (IBRs) reduces the short circuit level: a typical synchronous generator can deliver a significant overcurrent, 2-5 [7] p.u., for a relatively long time (minutes), while the component limitations of the IBRs result in overcurrent limits of less than 2 [7] p.u. (usually 1.1-1.2 p.u.). [4]
Inverter-based resources (IBR), if not running at full available power, can also be ramped extremely quickly (25% per second for wind, 100% per second for photovoltaics), [20] limited amount of kinetic energy can be extracted from a wind turbine, providing an extra 10% of its capacity for about half a second (after a half a second delay). [21]
Because inverter-based generation inherently lacks inertia, increasing penetration of inverter-based renewable energy generation could endanger power system reliability. [ 7 ] [ 8 ] Further, the variability of renewable energy sources (RES), primarily concerning photovoltaics (PV) and wind power, could amplify this issue by creating more ...
