ADEQUACY ASSESSMENT OF COMPOSITE POWER-SYSTEMS WITH HVDC LINKS USING MONTE-CARLO SIMULATION

Direct current (DC) links are finding increasing use throughout the world in the form of long distance transmission and asynchronous interconnections. System reliability studies of a composite generation and transmission system containing a DC link involve modelling the DC transmission line and then analysing the overall composite system with the DC link forming an integral part. This paper illustrates a technique for DC system reliability analysis using the Monte Carlo simulation approach. The procedure developed was tested on a model DC system and the results are presented. The basic MECORE program was extended to include a DC link within composite generation - transmission system adequacy assessment. This paper also presents the Monte Carlo techniques employed for the composite system study and the results obtained for the modified IEEE-RTS.
