Effectiveness of wind turbine fast frequency response control on electrically distanced active power disturbance mitigation

摘要

In a power system, increased wind energy penetration changes the dynamic system response to active power disturbances. Due to the lack of natural inertial response from converter connected wind sources, an advanced converter control is required for maintaining a transient frequency stability of modern power systems with high shares of renewable energy sources. This research examines the new wind turbine fast frequency response control capability on the addressing electrically near and distanced active power imbalances considering transient dynamics system parameters. The focus of this research is to analyse the effectiveness of wind turbine fast frequency response control in reduced inertia power system modelled as a four-inertial centre system. The study is done on the case of Croatian power system with “real life” data for power generation, wind production, primary frequency regulation, and load shedding schemes. The simulation and scenario analysis are conducted under the MATLAB/Simulink environment using detailed power transmission system model.
