Coordination Planning of Multiple Energies in Distribution Networks

In the context of the large-scale integration of renewable energy units into the grid, the coordinated operation of multiple energy types has become imperative for grid development. This paper begins by analyzing the characteristics of distribution network components and models the distribution network using an alternating current flow model. Subsequently, considering the uncertainty of renewable energy output and the seasonal characteristics affecting cold and heat loads, typical daily data is generated. Addressing the uncertainties of electricity, heating, and cooling loads, along with the seasonal variations in renewable energy output, a multi-scenario planning scheme is proposed. Validation is conducted through a simulation example involving a 33-bus system, demonstrating that the proposed scheme reduces costs while improving system economics, all while ensuring the provision of cold and heat loads.
