Tlic package utilises the fast cimulant tcchniqucs for siniulatitig tltc random outages of tlic gcncratitig units and thc load. To etisitrc good accuracy, the expansion technique b a d on Lagucrrc I’olyitoniials is used. Otic of the disadvantages of the traditional probabilistic simulation packages is that the chronology i s lost whcn the hourly load is converted to a load duration curvc. This produces unacceptable errors if llic system contains energy limitcct units, such as pumped storage units or non-dispatchablc tcclinologics, such as solar, wind etc. A new technique i n scheduling these units have bccn incorporated into FEL’SS. Tlic hourly Ihcrmal incrcmctitiil cost is evaluated using an ingenious tccliniquc, which avoids hourly evaluation.

Kevwords: Production costing, I’umpcd Storiigc Optiniisation, Keliability, LOLI’. To ovctcomc these problems, this paper initially describes an improved cumulnnt method of probabilistic power system siniulaitioti using the Laguenc polynotnial expinsion. In this method, Laguerre polynomials are used for obtaining the equivalent load duration probability dcnsity function from cumulants representing the load and generator outage probability density functions. A recursivc algoritlini is used for calculating moinenh arid cumulants wlliich enables practically any number of cutnulatits to be used in the simulation. It will be shown that this technique is superior in its accuracy when compaied with the traditional Gram-Charlier or the Edgeworth series bascd on tlic Hennite polynomial expansion. Another disadvantage of the traditional probabilistic simulation packages is that the chronology is lost when the hourly load is converted to a load duration curvc. This prodiuccs unacceptable errors if the systeni contains energy limited units, such as putnped storage units or non-dispatchable technologies, such as solar, wind etc. A new techniquc in scheduling these units have ‘ken incorporated into FEPSS. The hourly thermal incremental cost is evaluatcd using an i ngcnious technique, which avoids hourly evaluation. The papcr will describe the novel optimisation process used in FEI’SS to sclicdulc tlic pumped storage pumping opcrntion at night to ctisurc that the generation oE clcctricity during the day will always provide niaximuni saving. 1.
