| Summary: | This paper established a fully renewable energy system which takes solar energy, wind energy and biomass energy as primary energy and meets the demand of electricity, heat and cooling loads. Considering the uncertainty of both energy source and load, a day-ahead economic dispatch model based on two-stage robust optimization was built and solved by column constraint generation (C & CG) algorithm. The simulation results show that renewable energy can be fully consumed by giving full play to its multi energy complementary characteristics. At the same time, the conservatism of robust optimization can be effectively improved by adjusting the uncertainty adjustment parameters, so as to improve the operation economy of the energy system and ensure safe and stable operation. |
