Abstract

The invention relates to a medium-and-long-term wind power generation parameter prediction method and system. The method comprises the following steps: determining a wind power generation unit utilization rate of each historical medium-term period according to the abandoned power quantity and the actual power generation quantity of each historical medium-term period; determining wind power generation parameters of the to-be-tested medium and long term periods according to the wind power generation unit utilization rate of each historical medium term period; the technical scheme provided by the invention is simple, practical and good in universality, the predicted medium-and-long-term wind power generation parameters are accurate, and effective data support is provided for long-period electricity market transaction and maintenance plan arrangement.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a method and system for predicting medium and long-term wind power generation parameters. Background technique [0002] With the large-scale development and grid connection of wind power resources, the problem of wind power consumption has been brought. [0003] At present, cross-regional power trading adopts a trading model based on annual contracts and supplemented by monthly temporary transactions. In the process of signing long-term new energy trading contracts, it is necessary to consider the power generation capacity of wind power and photovoltaic stations in the next year or several months; When executing long-term new energy transactions, the process of decomposing new energy power generation into monthly power generation plans also requires wind power and photovoltaic power generation data. [0004] Therefore, the medium and long-term wind power generation...
