Description

technical field [0001] The invention relates to a multi-energy complementary comprehensive energy allocation optimization and operation method, which belongs to the field of resource allocation optimization. Background technique [0002] Multi-energy complementarity is a small-scale distribution power system that organically integrates distributed power sources, loads, and energy storage. Connecting distributed power sources to large power grids in the form of multi-energy complementarity is generally considered to be one of the most effective ways to utilize distributed power sources. However, since the installation plan may include easily controlled power sources such as distributed gas turbines, it may also include such Intermittent and uncontrollable power sources such as wind power and photovoltaics, the mutual switching and mutual influence of these power sources, coupled with the variability of power interaction with the external power grid, jointly result in the nece...
