The Joint Working Group C4/C2.58/IEEE was established to review voltage stability of power systems in the context of increased penetration of Inverter Based Resources (IBR) in electric power grids. The focus was to evaluate the adequacy of existing methods of voltage stability assessment in the present-day context. The developed technical brochure reviewed the definition of voltage stability and explained the role of voltage stability assessment within the voltage security assessment task of near real time power system operation. The overall conclusion is that the controllers implemented on IBRs makes a significant influence on short-term, but also long-term voltage stability. The presence of IBRs at distribution voltage levels contribute to the dynamic behavior of the power grid. Voltage stability assessment must incorporate these facts to ensure that the methods and tools accurately capture voltage stability limits.
