The penetration rate of renewable energy in the future new power system is increasing day by day. Distributed wind and photovoltaic energy input to the main grid will cause excess power to form a reverse flow in the feeder and increase the line loss of the distribution network. In order to reduce the loss of power transmission and promote the local consumption of new energy, this paper uses a large number of ice storage air conditioning clusters as the carrier to construct a framework for ice storage air conditioning clusters to participate in the microgrid economic dispatching, and analyzes the control advantages and the dispatching process of the ice storage air conditioning during cold storage and release process. Secondly, the uncertainty of microgrid distributed wind and photovoltaic output is modeled based on the scenario method. Considering the microgrid scheduling cost, line loss cost and conditional risk cost under the influence of uncertainty, the optimal scheduling model with the minimum total expected cost and the adjustment capacity and cost constraint set of each equipment in the system are constructed, and the uniqueness of the optimal solution of the model is verified according to the Lagrange multiplier method. The example simulation shows that the stochastic scheduling strategy in this paper can promote the economy of microgrid operation and deal with the risk of uncertainty. The ice storage air conditioning cluster can promote the local consumption of scenery and reduce the network loss caused by power reverse transmission, which is more economical than ordinary air conditioning and lithium battery.
