Method for determining capacity of energy storage apparatus for new energy support machine, and new energy support machine

Abstract

Provided in the present application are a method and apparatus for determining the capacity of an energy storage apparatus for a new energy support machine, and a new energy support machine. The method includes: determining the duration of a rotor of a doubly-fed induction generator participating in adjustment; determining a slip ratio of the rotor of the doubly-fed induction generator when same participates in the adjustment; and determining the capacity of an energy storage apparatus according to an active power of a stator of the doubly-fed induction generator participating in the adjustment, the slip ratio of the rotor when same participates in the adjustment, and the duration of the rotor participating in the adjustment. The method is intuitive and has a small calculation amount, and a determined capacity value is larger and more reliable, such that the engineering practicability is higher. By configuring an electrochemical energy storage apparatus of the capacity in a new energy support machine, the adjustment capability of a new energy station can be improved.
