摘要
The main purpose of the look-ahead dispatch is to manage operational uncertainties over the next several hours, with benefits for the exploitation of renewable energy resources. This paper describes a robust optimization (RO) model for wind power look-ahead dispatch. The model calculates allowable interval solutions for wind power generation and provides optimal economic solutions for conventional power generation to mitigate the uncertainty inherent to wind power. By introducing the interval values as control targets for wind farms, the method can reduce the curtailment of wind power and the frequency of regulation. Interval wind power look-ahead dispatch is a two-layer RO problem, which can be transformed into a quadratic programming problem using strong duality theory, allowing for a more straightforward solution. The results of numerical simulations using the IEEE RTS system, as well as field tests using a 1.8-GW transmission system, are reported.
