Problems solved by technology

Equivalenting wind turbines to conventional multi-state unit models can show the probability of wind turbine output, but due to the loss of time series information, it is difficult to accurately describe the impact of wind power generation anti-peaking characteristics; wind power is treated as a negative load, directly Subtracting from the load has certain feasibility for small-scale wind power grid connection

Abstract

The invention discloses a probabilistic production simulation method comprehensively considering a load and a wind power temporal characteristic. The probabilistic production simulation method is characterized in that: for a temporal intermittent characteristic, an anti-peaking characteristic, and a non-dispatchable characteristic of power output of a wind power unit, and that a temporal characteristic of the load is usually neglected in traditional probabilistic production simulation, four unit models are proposed according to different operating modes of a generator unit, and probabilistic production simulation is performed. According to the invention, the wind power temporal characteristic and impacts of various operating factors on the probabilistic production simulation when the generator unit is under different operation states can be studied quickly and reasonably, so that a more comprehensive mathematical model is established and computing efficiency is improved.
