Embodiment

[0160] (1) Parameter setting

[0161] 1) System overview

[0162] Such as Figure 4As shown, the energy types in the system of this embodiment include three types of electricity, natural gas, and heat. The power system is an IEEE 33-node system, the natural gas system is an 11-node system, and the thermal system is a 32-node system. The embodiment system includes two Energy hubs. Node EB24, node GB10 and node HB3 are connected through Energy hub I. The input of Energy hub I is electricity and natural gas, and the output heat energy is used to supply energy for the thermal system load. Energy hub II is connected to node GB11 and node HB6, and these two nodes provide natural gas and heat energy to Energy hub II respectively.

Abstract

The invention relates to a comprehensive energy system energy supply reliability evaluation method and a computer system. The method comprises the following steps: acquiring original parameters and atopological structure of a comprehensive energy system to be evaluated; obtaining a simulation model of the to-be-evaluated comprehensive energy system based on a sequential Monte Carlo method; performing topology analysis on the system state of the simulation model by adopting a node marking method to obtain a plurality of connected domains; and respectively carrying out state analysis on each connected domain, and carrying out reliability evaluation on the to-be-evaluated comprehensive energy system by adopting an energy supply reliability index system based on an energy use purpose and a user standpoint. Compared with the prior art, the method can consider energy consumption purposes and user standpoints of different types of users, has the advantages of high evaluation accuracy and thelike, and ensures safe and efficient operation of the comprehensive energy system.

Description

technical field [0001] The invention relates to the field of comprehensive energy, in particular to a method for evaluating the reliability of energy supply of a comprehensive energy system and a computer system. Background technique [0002] As the global energy crisis continues to intensify and environmental problems become increasingly severe, the traditional high-carbon energy development and utilization methods will be unsustainable. The famous American scholar Jeremy Rifkin pointed out in "The Third Industrial Revolution" that the industrial model based on the large-scale utilization of fossil fuels established in the second industrial revolution is coming to an end. In recent years, information support technologies represented by big data, cloud computing, Internet of Things, and mobile Internet, and energy technologies represented by renewable energy, distributed power generation, energy storage, micro-grid, and electric vehicles have developed rapidly. The Energy I...
