Abstract: In order to reasonably evaluate the fully renewable energy multi-energy complementary system, a comprehensive evaluation index system considering renewable energy resource endowment is proposed. Firstly, a fully renewable energy multi-energy complementary system that uses 100% renewable energy as an energy input is designed, including the system structure, the equipment configuration and the operation strategy. Secondly, according to the principle of index system construction, a comprehensive evaluation index system including the resource endowment (bearing resource reserves and characteristics) is established. Thirdly, aiming at the resource endowment index, the AHP-entropy weight-TOPSIS method is used to comprehensively evaluate the system. Finally, five representative cities are selected as the analytic cases according to the regional climate differences. The analysis results show that there is a positive correlation between the renewable energy resource endowment and the system evaluation results. The addition of resource endowment index makes the evaluation results more reasonable and reliable, which verifies the effectiveness of the proposed evaluation system. The evaluation method can not only effectively deal with the indicators like the resource endowments, but also make the evaluation results more differentiated, which can provide decision-making basis for the optimal allocation of renewable energy multi-energy complementary systems.
