[0025] The technical solution of the present invention will be described in detail below in conjunction with the drawings.
[0026] The present invention provides a reactive power compensation control method that considers the volatility of offshore wind power, takes into account the volatility of the offshore wind power access system, and improves the voltage stability of the system based on the network structure and real-time system information to obtain reactive power compensation. The control method includes the following steps:
[0027] Step S1, the known wind power access system is equivalent to a two-node system by multi-port Thevenin equivalent, and the voltage instability index Ivsi of each node in the wind power access system is calculated;
[0028] Step S2: Determine whether the node voltage instability index is out of limit, and the out of limit node is the key node of voltage stability, and calculate the control target of the key node of voltage stability;
[0029] Step S...
