Abstract: This paper describes a methodology based on safety factor concept and peak load considerations for a reliability evaluation of a generation system. This paper also refers to major research papers presented for the evaluation of reliability of power systems, reliability indices and modelling of power system components. Load models are considered as a straight line and a stepped load duration curve is used for reliability evaluation of system using Simpson|s 1/3rd rule. The probability of load exceeding the generating capacity has also been considered in Loss of Load Probability (LOLP) evaluation.

Keywords: Gaussian distribution; generation capacity; loss of load probability; mean capacity; mean load; peak load; stepped load duration curve; success probability; power system components; component modelling; reliability evaluation; power systems; safety factors.
