Abstract

An important operating aspect of all transmission systems is power system stability and satisfactory dynamic performance. A particularly problematic operating scenario occurs when conventional generation is operated at a low level but photovoltaic solar generation is at a high level. This paper addresses the impact of high solar penetration that results in potentially problematic low system damping operating conditions. An actual case study is reported in which real operating system data are used. Solutions to low damping cases are discussed and a solution based on the retuning of a conventional power system stabilizer is reported. The Larsen Swann method is used.
