The invention discloses a rural electric heating comprehensive energy system operation optimization method considering renewable energy uncertainty and thermal inertia. The method fully considers the flexible resources of the source, the network and the load of the thermodynamic system, improves the consumption level of renewable energy sources and reduces the comprehensive cost of the system. The source side cogeneration unit has an adjustable heat-power ratio, simultaneously, a afterburning boiler and electric heating equipment exist in the system, the output is flexibly adjusted according to the operation condition, the network side utilizes the transmission delay and the virtual energy storage characteristic of a heating power pipe network, the load side carries out detailed modeling on the dynamic heat process of the building, flexible resources of a rural electric heating comprehensive energy system are excavated, and electric heating coordination and complementation are realized. Meanwhile, uncertainty of distributed renewable energy sources is considered, and an opportunity constraint model is adopted to provide scheduling schemes with different probability guarantees. The method fully excavates flexible resources of the thermodynamic system, improves the efficiency of the energy system through multi-energy coordination, can effectively promote the consumption of renewable energy sources, and reduces the energy cost. |
