Abstract

The invention discloses a method, system, device and storage medium for controlling an output command of an offshore fan array. The method for controlling an output command of an offshore fan array includes the steps of: calculating the superimposed wind speed of the target fan at time t-1; according to the time t-1 Combine the superimposed wind speed of the target fan with the power output command of the target fan at time t-1 and the wind speed of the target fan at time t-1 to calculate the power output command of the target fan at time t; output the power output command of the target fan at time t, using The power output of the control target fan at time t. The offshore wind turbine array output command control method provided by the present invention uses a multi-scale evaluation system based on the wind speed and distance of the target wind turbine and adjacent wind turbines to independently establish the wind turbine output command value suitable for the current application environment. It not only allows the wind turbine station to carry out the most reasonable power distribution as a whole, but also takes into account the power output prediction of a single wind turbine through the wind speed superposition method.

Description

technical field [0001] The invention belongs to the field of offshore wind power generation, and in particular relates to an offshore wind turbine array output command control method, system, device and storage medium. Background technique [0002] At present, the domestic offshore wind power industry is developing rapidly, and there are a large number of domestic offshore wind power projects planned and under construction in recent years. With the large-scale access of offshore wind power to the grid in the coastal provinces of various provinces, the inaccurate output control commands of offshore wind turbine arrays caused by factors such as inaccurate wind power forecasting and anti-peaking characteristics may affect the stability of the grid. . [0003] At present, the overall control of offshore wind turbines in large-scale offshore wind farms is in an extensive state, that is, according to the real-time wind speed, the output power command target value of offshore wind...
