POWER GRID REACTIVE POWER CAPACITY CONFIGURATION METHOD AND TERMINAL FOR OFFSHORE WIND POWER LARGE-SCALE GRID-CONNECTION

Resumen de: EP4589801A1

Provided are a method and a terminal for configuring reactive power capacity of a power grid to which offshore wind power is connected on a large scale. Static voltage stability indices of substations in a regional power grid to which the offshore wind power is connected on the large scale and at multiple points and relative dynamic voltage drop area indices for an N-2 fault are calculated. Thus, weak nodes in voltage stability are located, thereby implementing a prediction of a risk to the voltage stability of the regional power grid. These nodes are used as candidate reactive power compensation configuration nodes. An objective function is established as the minimum total cost of reactive power compensation devices at the candidate reactive power compensation configuration nodes. A multi-type reactive power optimization configuration model including static voltage stability constraints, voltage stability constraints in a faulty state, and other constraints is solved. Thus, a configured static reactive power compensation meets a voltage regulation demand during normal operation of the power grid, and a configured dynamic reactive power compensation meets a demand for reactive power support in the event of a severe fault in an important transmission channel. In addition, the total cost of a reactive power compensation configuration is minimized so that a stable voltage and an economical reactive power configuration of a system with a high proportion of offshore wind power are
