The report modeled an electricity interchange trade between a PPS (Power Producer and Supplier) and a cogeneration user, and evaluated the trade using the optimizing simulation. In this simulation model, cogeneration user and PPS behave economically optimizing independently. The aim of this report was to evaluate the energy consumption under the economical electricity interchange. The computed estimations answered that the primary energy consumption was reduced in proportion to electricity interchange amount, even if the electricity efficiency of cogeneration was low than the grid's efficiency. From the comparison with energy formula and the computed estimation, the operation of cogeneration was shown to choose the heat-load-following mode and to utilize the waste heat. This was the reason to reduce the primary energy consumption and the energy cost, by interchange of CGS surplus electricity.
