Embodiment 1

[0054] A schematic flow chart of a method for exploring power-to-gas operation opportunities in energy systems provided by the present invention is shown in figure 1 shown, including:

[0055] Step 1: According to the obtained regional temperature data and energy consumption data, obtain the operation opportunity of the power-to-gas device between regions or between seasons;

[0056] Step 2: When there is an operation opportunity for the power-to-gas device between regions or seasons, according to the obtained intraday electricity price and load distribution data, obtain the operation opportunity of the power-to-gas device within the day.

[0057] The specific process of the method of exploring the operation opportunities of power-to-gas in the energy system is as follows. Wherein the order of step 101 and step 102 is only an example, step 101 or step 102 can be performed simultaneously, step 102 can be performed first and then step 101 is performed, or only one step in step ...

Embodiment 2

[0080] Based on the same inventive concept, the present invention also provides a system for exploring opportunities for power-to-gas operation in energy systems. Since the principles of these devices to solve technical problems are similar to the method for exploring opportunities for power-to-gas operation in energy systems, there are no repetitions Let me repeat.

[0081] The basic structure of the system is as figure 2 As shown, including: regional / interseasonal operation opportunity module and intraday operation opportunity module;

[0082] Among them, the regional / inter-seasonal operation opportunity module is used to obtain the operation opportunity of the power-to-gas device between regions or between seasons according to the obtained regional temperature data and energy consumption data;

[0083] The intraday operation opportunity module is used to obtain the intraday operation opportunity of the power-to-gas installation according to the obtained intraday electrici...

Abstract

The present invention provides a method and system for exploring an operation opportunity for electric-gas conversion in an energy system. The method comprises obtaining an operation opportunity of anelectric-gas conversion device between regions or seasons according to acquired regional temperature data and energy consumption data; when the electric-gas conversion device has an operation opportunity between the regions or seasons, according to the acquired distribution data of an intra-day electricity price and load, obtaining the intra-day operation opportunity of the electric-gas conversion device. The method and system use the big data method to explore the regional, seasonal and intra-day peak-valley differences between the energy consumption load and the energy consumption price, and seek for the arbitrage opportunity of the electric-gas conversion device and the opportunity for stabilizing a peak and valley to achieve the stable operation of a power system in order that the electric-gas conversion device operates economically and valuably.

Description

technical field [0001] The invention belongs to the technical field of energy data analysis, and specifically relates to a method and system for exploring opportunities for power-to-gas operation in energy systems. Background technique [0002] New energy has made outstanding contributions to the response to environmental pollution and energy crisis, but at the same time, its intermittent and fluctuating characteristics cannot track the load well, and it is easy to cause regional, seasonal and intraday peak-valley differences in energy consumption, thus A large amount of new energy power generation energy is discarded, resulting in energy waste. For this reason, power-to-gas technology is used to convert electric energy that is not easy to store in a large scale into natural gas that is easy to store or hydrogen that can be directly used by the chemical industry to improve the efficiency of new energy use; At the same time, it has the advantage of reducing natural gas energ...
