Urban energy infrastructure planning system and method

Abstract

The invention relates to an urban energy infrastructure planning system and method. The system comprises a cooling and heating, power and fuel gas demand module which calculates the cooling and heating, fixed power and fixed fuel gas demands of each area; a cooling and heating preparation cost module which calculates the cooling, heating and power preparation cost of each area; a cooling, heating and power preparation and transaction comprehensive optimization module which obtains the cooling, heating and power preparation quantities of each area and the cooling and heating transaction network of each area according to the cooling and heating demands and the cooling, heating and power preparation cost; a power, fuel gas and cooling and heating supply calculation module which calculates the obtained power, fuel gas and cooling and heating supply quantities of each area according to the cooling, heating and power preparation quantities of each area and the demands of the fixed power and the fixed fuel gas; and an energy infrastructure planning module which carries out the planning configuration of the power, fuel gas, an energy station room and a cooling and heating pipe network according to the power, fuel gas and cooling and heating supply quantities of each area and the cooling and heating transaction network. Compared with the prior art, the system can improve the energy supply and demand matching degree, and reduces the construction cost of facilities.

Description

technical field [0001] The invention relates to an energy planning system and method, in particular to an urban energy infrastructure planning system and method. Background technique [0002] Urban energy infrastructure planning is the basis for the construction of various energy transmission and distribution facilities such as electricity, gas, and heat. The planning scheme has an important impact on the level of construction investment and the matching degree of energy supply and demand. With the advancement of distributed energy technology, users have changed from pure energy consumers to energy consumers and some types of energy providers. The phenomenon of mutual conversion and mutual substitution of various energy sources at the user end is increasing, making The difficulty of scientific planning of energy infrastructure continues to increase. The current method of separate planning of various energy infrastructures is difficult to meet the requirements of various ene...

AI Technical Summary

Problems solved by technology

[0005] This top-down distributed planning of various energy sectors and based on empirical indicators ignores the mutual substitution effect of energy, and does not consider energy utilization planning on the user side, which can easily lead to energy supply structure imbalance and mismatch between supply and demand , which is not conducive to giving full play to the initiative of users to save energy independently
