Description

technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to a fuel cell-based multi-energy complementary heat and power cogeneration system and working method. Background technique [0002] With the rapid growth of the national economy, the demand for energy is increasingly strong, and the problems of energy shortage and environmental pollution caused by fossil energy are becoming increasingly acute. Solar energy and wind energy resources have great potential and can be used sustainably. They have played an important role in meeting energy demand, improving energy structure, reducing environmental pollution, and promoting economic development. They have attracted widespread attention from the international community. However, solar and wind energy are typically random and intermittent, and their grid-connected consumption faces huge challenges. Complementary operation among various types of power sources is an import...
