摘要：
This paper presents the solution to the security-constrained unit commitment (SCUC) problem with a detailed representation of high voltage direct current (DC) transmission system with current source converters (CSCs). The SCUC problem is decomposed into a master problem for solving unit commitment (UC) problem and hourly transmission security check subproblems that evaluate branch flows and bus voltages of integrated AC/DC transmission systems. The solution of the transmission security check subproblem is based on a linear programming (LP) formulation that minimizes AC bus mismatches subject to AC/DC transmission constraints. The final SCUC solution prescribes an economic and secure operation and control strategy for AC/DC transmission systems and coordinates DC power transfers for enhancing the economics and the security of AC transmission systems. Numerical tests illustrate the efficiency of the proposed AC/DC transmission model.
