供需调度嵌入的综合能源分布式自适应规划

The wide-area integrated energy system corresponds to the transmission level of the power system. Under the challenges of flexibility of energy supply and demand, variety of energy forms, and diversification of ownership of the system, the traditional power system planning method it inherits has exposed three great defects: the operation strategy that planning relies on is too rough, the optimization framework that planning builds is too simple, and the coordination of planning objects is deficient. This project is aimed at integrating the joint generation – transmission – demand – storage scheduling into the planning model, thus building a distributed adaptive robust optimization framework, and coordinating autonomous decision-makings of multi-energy facilities, so as to remedy these defects. The joint generation – transmission – demand – storage scheduling combines unit commitment, transmission switching, demand-side management and storage dispatch into a coordinated structure, forming the accurate operation strategy. Integrating the joint scheduling into planning to replace the optimal power flow, i.e. the traditional feasibility checker of configuration plans, constructs a unified operational planning model. The distributed adaptive robust optimization employs the distributed rule to deal with the diversification of the ownership of the energy system, and the adaptive policy to overcome the uncertainty of the multi-stage decisions themselves, forming a complete optimization framework. Finally, the accurate operation strategy and the complete optimization framework join to provide the mechanism for the coordination of the planning objects, which realizes the coordinated planning of the generation, transmission and storage facilities of the power, gas and heat forms.
