Predictor Corrector

A new continuation power flow method based on local geometric parameterization technique is proposed for voltage stability analysis of AC/DC hybrid power system. By means of the alternating iteration method as the AC/DC power flow algorithm, the proposed method takes the coupling relationship between AC and DC systems into account to modify Jacobian matrix of AC system. Constraints of variables in DC system are also considered, as well as the adjustment of converter transformers tap position and the conversion of converters control modes. Based on the predictor-corrector method, this paper adopts the geometric corrector, and changes the direction of convergence effectively. According to different operation modes of AC/DC system, accurate voltage stability limit and the entire PV curve can be acquired. Simulation results of IEEE test systems are used to show the validity of the proposed algorithm.

According to the structure and characteristics of HVDC system, this paper used the FTA (fault tree analysis) method to divide fault results of DC system into five transmission capacities: 0%, 25%, 50%, 75% and 100%, calculated results by incorporating DC system into AC system and used Monte Carlo simulation method to evaluate reliability of AC/DC hybrid system. Whats more, this paper established the model, algorithm and index system for risk assessment of AC/DC hybrid power system and developed corresponding software. Finally, an example was given to prove the correctness and validity of the proposed algorithm and software.
