An infinite source with series inductance is usually employed as a grid emulator in grid-connected distributed generation systems. Thus, high capacitance of a transmission cable (i.e., underground cable) is too significant to be neglected. As a result, the capacitance and inductance may cause system resonance, which, in turn, challenges system stability. This paper takes offshore wind farm as an example...
This paper investigates the resonance issues occurring in an HVAC grid-connected offshore wind farm and then presents an active damping control strategy accordingly. The offshore wind farm composed of wind turbine generators, voltage source converters, step-up transformers and HVAC submarine cables is considered in this study. The entire system is modeled by per unit values and emulated by a scaled-down...
