Abstract

Regionally distributed energy supply system is not only an important energy Internet physical carrier, but also the prototype and foundation of energy Internet. It focuses on physical technologies such as collaborative optimization between different energy sources. Distributed energy supply system has important research significance for exploring the internal operation mechanism of promoting advanced energy technology and different energy sources. In view of the special position of regionally distributed energy supply system in the transformation of energy system, it is particularly important to realize the scientific and reasonable coordinated operation and optimal dispatching of multiple energy in regionally distributed energy supply system, meet the demand for cooling and heating and power, and maximize the comprehensive economic benefits such as emission reduction and energy conservation. The coordinated operation and optimal scheduling of energy supply equipment in regionally distributed energy supply system is the core technology to ensure the safe, stable and economic operation of distributed energy supply system. Comprehensively considering the complex coupling characteristics of thermoelectricity and the random characteristics of renewable energy and load, coordinating the multi-directional energy flow in distributed energy supply system, studying the optimal operation mode of distributed energy supply system and optimal scheduling strategy will be the key research direction of energy Internet in the future. Based on the conventional cogeneration system, renewable energy generation is introduced. Firstly, the coupling interaction characteristics of photovoltaic power generation systems, wind power and other random power sources in the regionally distributed energy supply system and cogeneration system are considered, and the steady-state model is constructed. Then, combining the characteristics of operation of external energy supply conditions and energy supply equipment, The typical operation modes and power flow calculation methods of regionally distributed energy supply system are analyzed and combed. Relevant research will promote the efficient and intelligent development of regionally distributed energy supply system technology and improve the practicability of distributed energy supply system technology. Further improve the performance of using distributed energy technology to adapt to the dynamic characteristics of large-scale renewable energy access system. Make full use of the advantages of renewable energy green power generation to greatly reduce fossil energy emissions, save energy and reduce consumption, and reduce environmental pollution.
