Embodiment Construction

[0048] The invention provides a comprehensive energy system optimization planning method based on a double-layer busbar structure. Based on the double-layer busbar structure, the main frame of the comprehensive energy system optimization planning model is constructed by using a simulation evaluation-intelligent optimization dual module structure.

[0049] The outer layer of the double-layer busbar structure uses a single busbar structure to describe the composition of the comprehensive energy system. E.g figure 1 The outer structure of a typical integrated energy system is shown, including three buses: electric bus, hot bus, and cold bus. Various equipment are connected to the three buses, and the energy conversion device between the three buses realizes the communication between different media energy conversion. Through the single-bus structure of the outer layer, different power sources, heat sources, energy storage, and cold / heat / electric conversion devices can be modeled...

Abstract

The invention provides a comprehensive energy system optimization planning method and device based on a double-layer busbar structure. Based on the double-layer busbar structure, the present invention adopts the simulation evaluation-intelligent optimization dual-module structure to construct the main frame of the comprehensive energy system optimization planning model, further expands on the basis of the single-busbar structure, and adds a detailed inner layer for each busbar Topological structure, and independent simulation modeling is carried out according to the characteristics of each bus to ensure the accuracy requirements of each system; the invention not only considers the energy flow relationship between different energy forms in the comprehensive energy system, but also considers the energy flow relationship between the same energy form Based on the network structure and transmission characteristics of the network structure and transmission characteristics, layered modeling and iterative optimization are carried out. Through the thermoelectric decoupling method, the difference in heat and electricity transmission characteristics can be effectively reflected, and the dimension and complexity of system simulation can be effectively reduced, which is convenient for comprehensive energy analysis. The system is jointly optimized.

Description

technical field [0001] The invention belongs to the technical field of power system analysis, and in particular relates to a comprehensive energy system optimization planning method and device based on a double-layer busbar structure. Background technique [0002] With the development of the economy, the environmental and energy problems are becoming more and more serious, prompting people to constantly look for more effective ways to improve the efficiency of energy applications. As a comprehensive energy body centered on electricity, multi-energy coupling, and multi-network interconnection, the integrated energy system has formed the horizontal coupling of various forms of energy such as cold, heat, electricity, and gas, as well as energy production, conversion, transmission, and consumption. The vertical connection of multiple links breaks the existing independent energy supply mode of electricity, heat and gas, and is a new energy development and utilization mode that im...
