Eliminated volume of CO{sub}2 emissions and effects on economical efficiency of PV/FC system for various load patterns

摘要

PV/FC system is consisted of photovoltaic power system and fuel cell generation system. This system is very easy to operate it, and its capacity is flexible. In this paper, the annual amount of electric power loads and the amount of hot-water supply loads were aimed at the individual residence which is 14000kWh, respectively. This value is equivalent to four houses. The economical efficiency in considering annual CO{sub}2 emissions and an annual carbon tax was searched for by the simulation. As a result. it is found that the best system is 2kW in capacity of a fuel cell, and it is the operation mode of 2.2. Operation mode best from the viewpoint of economical efficiency is the method of fixed operation through every year, which is the mode I. It can be concluded from these things that PVIFC system is an outstanding system.
