Description

technical field [0001] The invention belongs to the field of optimal configuration of a distributed mixed cooling, heating, and electricity energy system, and specifically relates to a design method for a distributed cooling, heating, and electricity mixing energy system oriented to optimal comprehensive energy efficiency. Background technique [0002] The energy industry is not only a necessary prerequisite for national strategic security, but also an important guarantee for sustainable economic development. Although my country's energy production and consumption rank among the top in the world, there are still a series of outstanding problems in energy supply and utilization methods, such as irrational energy structure, low energy utilization efficiency, low proportion of renewable energy development and utilization, and energy consumption. The level of safe utilization needs to be further improved. Therefore, it is of great significance to transform from the traditional e...
