Inverter-based resource

<p>An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the <a href="/facts/Electrical_grid/RkWPqjmG">electrical grid</a> via an electronic <a href="/facts/Power_converter/sKmxxvHx">power converter</a> ("<a href="/facts/Inverter/L8cJc3Hu">inverter</a>"). The devices in this category, also known as converter interfaced generation (CIG) and power electronic interface source, include the <a href="/facts/Variable_renewable_energy/kynTl1t2">variable renewable energy</a> generators (wind, solar) and <a href="/facts/Battery_storage_power_station/mGVRuDGc">battery storage power stations</a>. These devices lack the intrinsic behaviors (like the <a href="/facts/Inertial_response/1P9fI8kL">inertial response</a> of a <a href="/facts/Synchronous_generator/NY4NsL9n">synchronous generator</a>) and their features are almost entirely defined by the control algorithms, presenting specific challenges to system stability as their penetration increases, for example, a single software fault can affect all devices of a certain type in a <a href="/facts/Contingency_(electrical_grid)/GI2Ap0HI">contingency</a> (cf. section on Blue Cut fire below). IBRs are sometimes called <i>non-synchronous generators</i>. The design of inverters for the IBR generally follows the <a href="/facts/IEEE_1547/gGkdr05q">IEEE 1547</a> and <a href="/facts/North_American_Electric_Reliability_Corporation/AtSDgddP">NERC</a> PRC-024-2 standards.
