AI Technical Summary

Technical Problem

With the increasing proportion of new energy sources and the gradual retirement of traditional thermal power units, the planning of offshore wind power is difficult to match with the load, resulting in wind curtailment, serious waste of resources, and a lack of effective methods for assessing the wind power acceptance capacity of the receiving-end power grid.

Method used

By constructing an operation optimization model for the receiving-end power grid, and combining power balance, branch capacity, wind power output, and load curtailment constraints, a wind curtailment rate minimization objective is established. The analytical expression for wind power absorption is calculated using a parametric programming algorithm, and the wind power acceptance capacity of the receiving-end power grid is evaluated.

Benefits of technology

It enables the assessment of the wind power acceptance capacity of the receiving-end power grid, optimizes wind power utilization, reduces wind curtailment, and ensures the efficient and safe operation of the new energy power system.
