Toward the renewable energy era where the electricity is based 100 % on renewable energy sources, the power systems are experiencing operational challenges due to lack of short-circuit power and inertia support. This may cause a cascade failure or even a collapse of the whole system. In addressing this issue, synchronous condenser as a reborn technology which not only supports voltage regulation but also supplies inertial response and short-circuit power for the systems. This paper validates the synchronous condenser benefit at Talega substation in southern California which is equipped with a modern and advanced control technology for synchronous condensers. Based on the measurement data from phasor measurement unit (PMU), it can be concluded that synchronous condenser is a critical key
for the system frequency stability improvement and short-circuit power support of renewable-based systems.
