The invention relates to a 
microgrid multi-energy joint 
optimal scheduling method. The method includes: step 1, on the basis of force application conditions of 
energy supply equipment and operating states of 
energy storage equipment in different scenes, constructing a 
physical model of a multi-
energy system; step 2, establishing unit mathematical models, including a 
wind power generator model, a 
photovoltaic power generation model, a micro-gas 
turbine model, a fuel 
cell model and an 
energy storage model, of the 
microgrid multi-
energy system; step 3, in order to realize lowest comprehensive cost in 
system operation, constructing a 
microgrid multi-energy 
optimal scheduling model by taking DG operation constraints, 
system safety constraints and multi-
energy coupling characteristics into comprehensive consideration; step 4, on the basis of reversed order 
dynamic planning, solving the microgrid multi-energy 
optimal scheduling model to obtain a microgrid multi-energy joint optimal operatingstrategy. By the microgrid multi-energy joint optimal scheduling method, operating demands in different scenes can be met, 
electricity-thermal coordinated optimal scheduling schemes are provided for operating of a comprehensive energy microgrid in different scenes, and high integral operating efficiency and high 
economic benefits are realized.
