Distributed Algorithm for Robust Economic Dispatch of Integrated Transmission and Distribution System Considering Wind Power Uncertainty
As wind power is widely integrated into transmission systems and distribution systems in centralized and distributed forms
it is a new challenge how to implement the coordinated economic dispatch of integrated transmission and distribution systems to ensure the economy and security of the whole system considering the uncertainty of wind power outputs. In this paper
firstly
a robust economic dispatch model of integrated transmission and distribution systems considering the wind power uncertainties is proposed
and a polyhedral uncertainty set is adopted to describe the uncertainty of wind power outputs. Secondly
under the framework of the column and constraint generation (C&CG) algorithm
a distributed algorithm based on Lipschitz dynamic programming and analytical target cascading is proposed for the C&CG master problem and C&CG sub-problems
respectively
to ensure the relative independence of information between the transmission system and distribution system. Finally
the simulation is carried out on a small integrated transmission and distribution system and an actual integrated transmission and distribution system. The results verify the correctness and effectiveness of the proposed algorithm.
