With the frequent occurrence of extreme meteorological events
the uncertainty of power supply increases
and the existing multi-energy microgrid dispatching model cannot effectively guarantee power supply
which also leads to high economic losses. Therefore
to solve this problem
a minimum cost toughness (day ahead) dispatching model of multi-energy microgrid under extreme weather is proposed. According to the load demand and emergency measures in the next 24 under extreme weather
the scarcity of data and the high volatility of renewable energy output power in this case are considered
and multi-energy coordinated power supply scheduling is completed at the minimum cost to ensure the continuous and stable operation of the system. It is proved that the model has the minimum cost in scheduling and its local uniqueness in mechanism
and "marginal optimality" is proposed as the rationality test method of the model output. Experimental analysis shows that in extreme weather
the traditional model will lead to the mismatch between scheduling strategy and actual supply and demand
increasing the economic loss caused by temporary coordination
but in extreme weather
the minimum cost resilient scheduling model of multi-energy microgrid can effectively reduce the power supply gap
shorten the gap time to 0.8
and reduce the total economic loss by 25.8% compared with the traditional model.
