This paper presents a methodology to evaluate the EEG as well as overall LOLP (loss of load probability), which is an index for system reliability of multi-area interconnected systems with wind generators, as well as conventional fossil fuel based generating units. The proposed model is also capable of tracking the energy export incorporating the multi-state probability model for wind generator which output varies with time and season.展开更多

文摘Due to randomness of wind generator's availability, power system planners have big concern on EEG (expected energy generation) and system reliability of power system with wind generators. This paper presents a methodology to evaluate the EEG as well as overall LOLP (loss of load probability), which is an index for system reliability of multi-area interconnected systems with wind generators, as well as conventional fossil fuel based generating units. The proposed model is also capable of tracking the energy export incorporating the multi-state probability model for wind generator which output varies with time and season.
