Problems solved by technology

[0006]Aiming at the disorderly grid connection of distributed new energy systems and unbalanced supply and demand in cities, which affect the safe and stable operation of new energy systems and distribution networks, this The invention proposes an Energy Internet planning method based on mixed integer programming. The objective function is to minimize the operating cost of the system. It not only involves power system issues, but also considers the constraints of the natural gas system, the coupling of the power and natural gas systems, and the impact of the two systems on energy. The influence of the operation of the Internet system, so as to realize the optimal planning of the energy Internet system

Abstract

The invention provides an energy internet planning method based on mixed integer programming. The method comprises the following steps: S1, collecting relevant data information required for modeling;S2, establishing an energy internet model based on mixed integer programming according to the constraint relationship of the relevant data information; S3, linearizing the energy internet model; and S4, using the linearized energy internet model to plan the energy internet. The lowest operation cost of the system is taken as the objective function, the power system problem is involved,the constraint of the natural gas system, the coupling of the power and natural gas systems and the influence of the two systems on the operation of the energy internet system are considered, thus realizing the optimal planning of the energy internet system.

Description

technical field [0001] The invention belongs to the field of power system planning, and in particular relates to an energy internet planning method based on mixed integer programming. Background technique [0002] The rapid promotion of smart cities and "Internet +" smart energy has greatly promoted the development of distributed power, electric vehicles and other smart power services. The customer-side energy consumption, energy storage, and energy supply equipment are increasingly abundant, and its convenient and flexible The demand for access to the smart energy network is increasingly urgent; in addition, with the development of society and economy, users' demand for energy supply is not limited to the traditional mode, and their demand for diversified and personalized interactive services is increasing. [0003] Faced with the above-mentioned demand for energy services, it is necessary to rely on the concept and technical system of the Energy Internet to solve them. Am...
