Monthly Contract Electricity Compilation Method Based on Wind Farm Operation Characteristics

doi:10.11930/j.issn.1004-9649.201705102

Abstract

Abstract: The monthly contract electricity quantity for power grid is usually compiled using the average decomposition method, but its implementation is difficult for dispatching. A new monthly contract electricity quantity compilation method is therefore proposed based on the operation characteristics of wind farms. On the basis of the rolling correction of the monthly decomposition values of the annual contract electricity quantity, the wind farm operating characteristic indices are established with consideration of the prediction error, output volatility and load-following features of wind power. Considering the constraint range of wind farms' load rates, the monthly contract electricity quantity of each wind farm is worked out. The compilation result can satisfy the constraint of contract electricity of each wind farm, and the operation characteristics of each wind farm is considered in electricity allocation. A case study has proved the effectiveness of the proposed method.

Key words: wind farm, rolling correction, operation characteristics, load rate constraint, monthly contract electricity quantity
