DESCRIPTION:Inverter-based resources (IBRs) are proliferating in distributi
 on and transmission systems. These resources have been driving changes in 
 industry paradigms\, grid codes\, standards\, and recommended practices. O
 ne established utility system design is effective grounding for ground fau
 lt overvoltages (GFOV). This was derived entirely on the premise of a trad
 itional grid\, with utilities conforming their practices over the decades 
 with the expectation of this topology to continue. As IBRs proliferate\, t
 raditional practices are becoming ineffective in depicting expected behavi
 or. As a result\, management of GFOV becomes critically dependent on IBR c
 ontrol algorithms and on the negative sequence impedance of the aggregate 
 load of a distribution feeder. This requires a shift in direction for tran
 smission and distribution operators. These controls also affect Load Rejec
 tion Overvoltage (LROV). This presentation includes an electric utility’
 s lessons learned in the interconnection of a range of large scale IBRs to
  its distribution grid. Simulation and measurement case studies are presen
 ted to illustrate the drawbacks of conventional practices. It also exempli
 fies how utilities can manage the problems and presents a forward-looking 
 perspective on the evolution of rules\, standards\, and practices.\n\nSpea

X-ALT-DESC:Description: <br /><p>Inverter-based resources (IBRs) are prolif
 erating in distribution and transmission systems. These resources have bee
 n driving changes in industry paradigms\, grid codes\, standards\, and rec
 ommended practices. One established utility system design is effective gro
 unding for ground fault overvoltages (GFOV). This was derived entirely on 
 the premise of a traditional grid\, with utilities conforming their practi
 ces over the decades with the expectation of this topology to continue. As
  IBRs proliferate\, traditional practices are becoming ineffective in depi
 cting expected behavior. As a result\, management of GFOV becomes critical
 ly dependent on IBR control algorithms and on the negative sequence impeda
 nce of the aggregate load of a distribution feeder. This requires a shift 
 in direction for transmission and distribution operators. These controls a
 lso affect Load Rejection Overvoltage (LROV). This presentation includes a
 n electric utility&rsquo\;s lessons learned in the interconnection of a ra
 nge of large scale IBRs to its distribution grid. Simulation and measureme
 nt case studies are presented to illustrate the drawbacks of conventional 
 practices. It also exemplifies how utilities can manage the problems and p
 resents a forward-looking perspective on the evolution of rules\, standard
 s\, and practices.</p><br /><br />Agenda: <br /><p>12:00 - event begins</p
