Abstract

The invention provides a regional energy system source-load coordinated operation simple method based on electricity-to-gas conversion equipment. The method comprises the following steps: collecting day-ahead prediction electrical load and thermal load data, energy conversion equipment parameters and energy storage equipment parameters in a regional energy system; establishing a regional energy converter model containing the electricity-to-gas conversion equipment according to the acquired energy conversion equipment parameters and the energy storage equipment parameters; determining an actioncritical value of the energy converter based on the acquired day-ahead prediction electrical load and thermal load data, and dividing the energy converter into five operation modes according to the action critical value of the energy converter; and determining a source-load coordinated operation scheme of the regional energy system according to the action critical value of the energy converter and the five operation modes of the energy converter. The method is convenient to operate, peak clipping and valley filling are conducted on electric loads through multi-energy complementation, unit capacity construction can be reduced, power grid upgrading is delayed, and natural gas, electric energy and heat energy markets are promoted to be connected more closely.

Description

technical field [0001] The invention relates to the technical field of source-load coordinated operation of regional comprehensive energy systems, in particular to a simple method for source-load coordinated operation of regional energy systems based on power-to-gas equipment. Background technique [0002] At present, different forms of energy such as electricity, gas, and heat in my country are operated separately in construction planning and actual operation. The comprehensive energy utilization efficiency is low, and the advantages of various energy sources have not been fully utilized. Considering the strong coupling between energy sources and low energy utilization efficiency, the centralized collaborative optimization development of multiple energy sources is conducive to improving the comprehensive utilization efficiency of energy and promoting the integration of multiple energy networks.
