Reliability Evaluation of Power Systems pp Cite as. The previous chapter illustrates the application of basic probability methods to the evaluation of static capacity adequacy. The basic indices illustrated in Chapter 2 are the expected number of days or hours in a given period that the load exceeded the available capacity and the expected energy not supplied in the period due to insufficient installed capacity. These are useful indices which can be used to compare the adequacy of alternative configurations and expansions. They do not, however, give any indication of the frequency of occurrence of an insufficient capacity condition, nor the duration for which it is likely to exist.

Digital Computer Algobithms for the Calculation of Generating Capacity Reliability Indices Abstract: This paper presents a complete and consistent set of equations suitable for digital computer calculation of generating capacity reliability indices. Each set of equations is accompanied by a brief and relatively simple numerical example to illustrate the proposed procedure.
The algorithms detailed commence with the equations for building capacity models required in the Loss of Load Expectation technique using two state and multi-state generating unit representations. These algorithms are then extended to the equations required in the Frequency and Duration method. Article :. Date of Publication: Jan. Need Help?

Each interconnected system can then operate at a given risk level with a lower reserve than would be required without the interconnection . This condition is brought about by the diversity in the probabilistic occurrence of load and capacity outages in the different systems . The actual interconnection benefits depend on the installed capacity in each system, the total tie capacity, the forced outage rates of the tie lines, the load levels and their residual uncertainties in each system and the type of agreement in existence between the systems .
