| Abstract: |
| The concept of exergy is introduced to represent the homogenization of multi heterogeneous energy resources such as wind energy, solar energy, water energy and so on. An exergy analysis method is adopted to calculate the efficiency of the MEGPS(Multi-Energy Generation Power System) including wind power, photovoltaic power and hydro power. The input exergy and output exergy of the MEGPS are calculated according to the proposed exergy analysis model. The efficiency indexes such as the total exergy efficiency, sustainability index and the unite exergy loss ratio for the MEGPS are proposed to evaluate the energy efficiency of the MEGPS. Case studies are carried out to prove the validity and applicability of the proposed model. The proposed method provides scientific foundation for enhancing the utilization of the MEGPS. |
