A control strutture for thè Unified Power Flow Controller (UPFC) based on multipul.sc Neutral Point Clamped (NPC) Inverters is proposed and thè relevant dynamic analysis is described. In particular, attention is focused on thè control design for both shunt and series converters, together with a ncw solution for thè regulator of thè de link voltage sharing across de capacitors of thè multilevel inverters. For such purpose, an energy-based approach, which uses thè notion of incrementai energy and passivity, is investigated. In order to test this approach, a detailed UPFC model has been developed in ATP using 24-puIse NPC inverters. Simulation results about UPFC dynamic performance, effects of increasing transmission capacity and damping low-frequency oscillations are reported.

Abstract
A control strutture for thè Unified Power Flow Controller (UPFC) based on multipul.sc Neutral Point Clamped (NPC) Inverters is proposed and thè relevant dynamic analysis is described. In particular, attention is focused on thè control design for both shunt and series converters, together with a ncw solution for thè regulator of thè de link voltage sharing across de capacitors of thè multilevel inverters. For such purpose, an energy-based approach, which uses thè notion of incrementai energy and passivity, is investigated. In order to test this approach, a detailed UPFC model has been developed in ATP using 24-puIse NPC inverters. Simulation results about UPFC dynamic performance, effects of increasing transmission capacity and damping low-frequency oscillations are reported.Pubblicazioni consigliate
