In this paper, a novel approach is proposed to build model for a multi-heterogeneous energy power generation system(MHEPGS) including wind power, solar power and hydro power. The exergy flux, exergy flow potential, exergy flow potential difference and exergy resistance are firstly defined based on exergy theory. The exergy equivalent model for the MHEPGS is constituted by exergy source series with the exergy resistance, which are represented by exergy flow potential and exergy resistance from the angle of force and resistance. Result show that the equivalent exergy model can correctly reflect the output of the MHEPGS.
