Modelling the partial planned outages in production costing simulation

摘要

This paper presents two ways of modelling such scheduled maintenance whose length is less than that of the simulation period (called partial planned or scheduled outages in the paper). The present author suggests using modified forced outage rate instead of derated capacity in this case. The effect of the different representations is shown on a very simple numerical example by comparing the loss-of-load probability, the energy not served and the expected energy generations of the units. The paper concludes that the modification of the forced outage parameter of units is more appropriate than derating the capacity.
