Abstract :
This paper presents the modeling of high-voltage direct current (dc) transmission systems with voltage-source converters (VSCs) in security-constrained unit commitment (SCUC). The impact of VSC-DC transmission system on the economics and the security of integrated ac/dc transmission systems is discussed. The nonlinear ac/dc equations are linearized and the Newton-Raphson method is utilized to solve the linearized network in the base case and contingencies. The SCUC solution will determine the optimal hourly schedule of controllable VSC-DC transmission systems in electricity markets. Numerical examples show the efficiency of the proposed model.
