Description

technical field [0001] The invention belongs to the technical field of integrated energy system operation and control, and in particular relates to a day-ahead optimization scheduling method for a multi-energy complementary system that considers the maximum consumption of new energy. Background technique [0002] With the continuous development of society, the contradiction between energy utilization and environmental pollution is becoming more and more obvious. At this stage, fossil fuels still occupy a large proportion in my country's energy consumption system, which restricts the development of social economy to a certain extent. In order to achieve sustainable development, my country is working hard to upgrade its energy structure in an all-round way, gradually transforming to a non-fossil, efficient and environmentally friendly energy operation system. It is of great practical and far-reaching significance to realize the cascade efficient utilization of energy and prom...
