Abstract
The report modeled an electricity interchange trade by a PPS (Power Producer and Supplier) and a cogeneration, and evaluated the interchange trade using the numerical example. The PPS and the CGS user behave economically themselves in the model. It is new that not an electric power company but PPS trades the surplus electric power.
From the numerical example, the effect of electricity price and gas prices is different between commercial sector and industrial sector when maximizing the PPS profits. An electricity interchange gives profits to three groups (the PPS, the CGS user, and the unspecified general user) who participate in trades. However, it was shown that the PPS cannot gain only few portions of the whole interchange profits although the PPS determines the purchase price for the CGS user.
