A new reactive power optimization model involved the probability of voltage violation (PVV) and power losses to resolve the stochastic impact of wind power injection on voltage regulation. The derivation of PVV is given and applied to a variable-speed constant-frequency (VSCF) wind turbine firstly which is calculated by combining the probability of wind farm power output and the relationship between...
A comparison is conducted on FRT ability of latest Grid Code requirements for wind farm integration between China and selected EU countries. The main causes of the differences are investigated. The author tried to predict the future trend of regulations and illustrate some clues of them.
A research on differences of latest Grid Code requirements for wind farm integration between China and selected EU countries are conducted. The similarities and differences of these Grid Codes in the aspects of low voltage ride-through ability, transient fault ride-through requirements, negative phase sequence requirements and reactive power control requirements are compared. The main causes of these...
A research on differences of latest Grid Code requirements for wind farm integration between China and selected EU countries are conducted. The similarities and differences of these Grid Codes in the aspects of active power/frequency control, reactive power/voltage control and fault ride-through capability are compared. The main causes of these differences are investigated and the author tried to...
Taking Excel as the development platform, one offshore wind turbine foundation monitoring system software is developed merging two excellent analysis softwares, namely FlexPDE expert in multi-physics coupling simulation and ANSYS expert in structural analysis and display features. They are integrated together, the influence of seabed instability on the pile response could be considered, so the pile...
