Inertia and Frequency Support From Britain's AC Powered Trains

The penetration of converter connected generation is increasing globally, bringing with it valid concerns over the stability modern electricity network. In terms frequency stability, provision inertia and support from interfaced has been topic significant research a wide range systems considered. One resource that avoided attention GB rail electrical rolling stock. Everyday thousands trains run on strict schedule, travelling at high speeds considerable mass all acting as one large energy store. AC possess regenerative braking allowing for this to be harvested. With simple software modifications can extracted during events. This article investigates power available response throughout working day. A sensitivity analysis parameters conducted work looks future by considering trains. between 300–850 MW estimated one-minute response. calculated profile was then used investigate effect would have had 9th August cut occurred in U.K. 2019.
