Problems solved by technology

[0003] The coupling relationship between electric energy and natural gas energy continues to intensify, but the existing technology lacks consideration of the interaction between the electric power market and the natural gas market, resulting in the inability to guide the joint dispatch of the two systems with a reasonable market price signal
At the same time, energy market participants, energy city operators, and energy system operators lack technical support and cannot cooperate reasonably, which limits the coordinated dispatch of electricity and natural gas in the context of multi-energy interaction

Abstract

The invention provides an electric power and natural gas joint scheduling method and system used under a multi-energy interaction background. The method comprises the following steps: predicting current electric power price data and natural gas price data; obtaining a current electric power quotation and a corresponding sales volume and a current natural gas quotation and a corresponding sales volume by using a participant decision model; establishing an energy optimization transaction model to obtain an optimal power price, a corresponding trading volume, an optimal natural gas price and a corresponding trading volume, and obtaining power clearing information and natural gas clearing information; the electric power system and the natural gas system are sequentially verified based on the clearing information of the electric power and the clearing information of the natural gas, and if the market clearing information does not meet the safety constraint requirements of the electric power system and the natural gas system; if yes, the clearing information of the power system and the clearing information of the natural gas system are adjusted through the power system rescheduling model and the natural gas system rescheduling model till the preset safety constraint requirements of the clearing information and the clearing information of the natural gas system are met.

Description

technical field [0001] The present invention relates to the technical field of power dispatch automation, in particular, to a method and system for coordinated dispatch of an electric power system and a natural gas system. Background technique [0002] The current research on the dispatching of electricity and natural gas generally takes into account the difference in physical properties between the electric power system and the natural gas system, and only relies on the natural gas power generators that jointly participate in the two systems to transmit system information, and the electric power system and the natural gas system are still dispatched independently. [0003] The coupling relationship between electric energy and natural gas energy is increasing. However, the existing technology lacks consideration of the interaction between the electric power market and the natural gas market, which makes it impossible to guide the joint dispatch of the two systems with reasona...
