Abstract

In order to fully utilize all kinds of energy in the coal mine integrated energy system, a distributed robust optimal scheduling method of the coal mine integrated energy system based on the Imprecise Dirichlet model is proposed to address the uncertainties of derived energy and renewable energy. Firstly, considering the problem of renewable energy consumption, a power-to-gas device is added to the traditional comprehensive energy system to increase the proportion of renewable energy utilization. Secondly, the distributed robust method is used to represent the uncertainty of mine-derived energy and renewable energy, and the fuzzy set containing the true distribution of derived energy and renewable energy output power is constructed from the historical data by the Imprecise Dirichlet model, and then the interval expression of the output power satisfying a certain degree of confidence is obtained, the distributed robust optimization model of the coal mine integrated energy system is constructed. Finally, the column and constraint generation （C&CG） algorithm is used to solve the model, and the effectiveness of the model is validated using data from a coal mine in Shanxi Province.
