Abstract

The invention relates to a park hybrid energy system optimization scheduling method based on energy hubs. The method includes the following steps of: (1) power exchange modeling inside the energy hubs; (2) energy storage system modeling in the energy hubs; (3) power exchange modeling between the energy hubs; (4) park hybrid energy system modeling; (5) optimizing the day-ahead scheduling model; and(6) acquisition of a scheduling plan. The optimization scheduling method can fully excavate the mutual support capabilities among different energy forms such as electric / cryogenic / thermal energy, andhelps to improve the economical efficiency of HEP operation, achieves a significant reduction in the energy supply cost of the park hybrid energy system, is easy and fast to use, and has a very goodpractical value.

Description

technical field [0001] The invention belongs to the technical field of comprehensive energy systems, in particular to an energy hub-based optimal scheduling method for park hybrid energy systems. Background technique [0002] With the increasing demand for energy in modern society, the shortage of energy and environment has become increasingly serious, which has brought great harm to the sustainable development of human society. The multi-energy park hybrid energy system HEP (hybrid energy park) with distributed power supply and combined cooling, heating and power system CCHP (combined cooling, heating and power) as the main energy supply unit has the advantages of clean energy utilization, improved energy utilization efficiency, low The characteristics of carbon environmental protection have achieved rapid development in the past two years. This system can effectively alleviate the contradiction between energy consumption growth and environmental protection, and plays a ve...
