A Decentralized Coordinated Dispatch Approach for Interconnected Power Grid With Wind Power via HVDC Tie-Line
摘要
Abstract
For day-ahead security-constrained unit commitment (SCUC) of interconnected power grid via HVDC tie-line with wind power,a decentralized coordinated dispatch model based on analytical target cascading (ATC) is proposed.In order to make full use of flexible adjustment ability of HVDC tie-line to promote trans-regional accommodation capacity of wind power,refined modeling of complex operating characteristics of HVDC tie-line is performed in this paper.On this basis,HVDC tie-line transmission power and generator output are coordinated and optimized.Day-ahead power generation problem is decomposed into master optimization problem of the upper-level dispatch center and sub optimization problems of the lower-level dispatch centers.The upper-level dispatch center is responsible for coordinating tie-line power flow of the interconnected power grid,and the lower-level dispatch centers solve their own SCUCproblem in a parallel manner.A 12-bus 2-area interconnected test system and a 2-area interconnected test system via HVDC tie-line modified from New England 39-bus system are utilized to illustrate effectiveness of the approach.Results indicate that the proposed method is in accordance with hierarchical and partitioned scheduling mode in China and helps to improve wind power accommodation ability.关键词
