Abstract: In order to improve the utilization rate of clean energy and promote the stable and low-carbon

operation of the microgrid，a low-carbon optimal dispatching model based on load side flexible resources was

established. According to the flexibility resource analysis，the flexibility resource modeling of load side was carried

out，and the low-carbon benefit was regarded as one of the sub objectives of the optimal operation. By establishing

the penalty function，the carbon emission generated in the whole process of the microgrid was minimized. The

genetic algorithm based on simulated annealing was used to solve the established model to verify the effectiveness

of the established low-carbon optimal scheduling model. Experimental results show that the effective use of load

side flexibility resources can effectively stabilize the fluctuation of load curve，promote the consumption of clean

energy and enhance the environmental benefits of microgrid.
