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 (Reliability Test System)
