Abstract
The thesis presents some approaches that can be used in the evaluation of approaches
the reliability of electric power systems
The first approach is used in the field of generation reliability . It is a quali¬tative approach for the evaluation of the loss of load et titian ( COLE ) which is based on the eigen - system technique . The a --=ac:n is used ja per
.
form a sensitivity study a mong different generation system models W
can be convolved with an appropriate load model to produce system risk in¬dex .
The second approach is used in the field of electric transmission , In this field it is necessary to calculate the steady state probability of a multi - stage Markov system . The importance of the calculation of the steady state proba¬bility in electric power system is evident since it contains repairable compo¬nents . The proposed approach is based upon the eigen - system method
calculate the steady state probability .
The third approach is used in the field of bulk generation and
sion reliability evaluation.It is a new technique to calculate the in¬dex at individual load buses, in any electric power net work .
The loss of load probability ( LOLP ) is a measure of the redabL=v
this evaluation . The approach is based on the minimal pa& szm ad dual fault tree techniques - This approach shows that the loading ate- - - -;z 15 a must in the evaluation of reliability , since it determines :he d---:,a --n of the power flow in each and every element of the system .
