A Study of Dynamic Characteristics of Series-Connected Wind Farm Using a Simulation Model that can Reduce Computational Load

Simulations of dynamic performances of a series-connected wind farm output, consisting of a number of wind turbine/generators (PMSGs) and current-source thyristor converters, are investigated. Simultaneous simulation of the entire wind farm is hard to execute due to excessive computing load and memory consumption. For this reason, this study proposes a simplified model in which the PMSG and thyristor rectifier portions are expressed simply. First, simulation results from this model are compared with results from that of detailed simulation to show the usefulness of this model. Finally, simultaneous simulations for the entire wind farm are executed to investigate the effect of integrating a large number of wind power outputs on smoothing output fluctuations in the wind farm.
