Abstract: Incremental Transmission Loss (ITL) factors have been widely used for decades as part of the solution of the classical power dispatch problem. In recent years, ITL factors have acquired renewed importance because they can be integrated in the spot pricing problem in order to allocate transmission losses among market participants. However, uncertainty in demand consumption as well as generation from renewable sources either with or without stochastic behavior, strongly affects nodal power injections and consequently the ITL factor pattern. This paper demonstrates that the effect of uncertainty upon ITL factors computation can be efficiently assessed using fuzzy programming. At a given operating point, location and time specific fuzzy ITL factors can be obtained from the results of running a Fuzzy Power Flow program where load and generation are represented as fuzzy sets. A general algorithm is developed and tested. Fuzzy set techniques provide a whole spectrum of fe!
asibility of the spot prices applied to each market agent. Proposed methodology has been applied to the 3-bus test system for didactic purposes.
Keywords: Incremental transmission loss factors, loss allocation, spot pricing.
