Optimal scheduling method and system for electricity-gas-heat comprehensive energy system

Abstract

The invention discloses an optimal scheduling method and system for an electricity-gas-heat comprehensive energy system. The method comprises the following steps: constructing an electricity-gas-heatlow-carbon economic scheduling model based on a stepped carbon transaction mechanism; constructing an objective function and constraint conditions of a low-carbon optimization model based on the electricity-gas-heat low-carbon economic dispatching model; and solving the low-carbon optimization model to obtain low-carbon optimization parameters, performing low-carbon scheduling on the comprehensiveenergy system according to the low-carbon optimization parameters, and therefore, proving the reasonability of the stepped carbon transaction mechanism for low-carbon scheduling.

Description

technical field [0001] The present invention relates to the technical field of energy optimization scheduling, in particular to a method and system for optimal scheduling of an electric-gas-thermal comprehensive energy system. Background technique [0002] The world's carbon emissions are increasing day by day, and reducing carbon emissions has become the consensus of all countries. my country promised in the "Paris Agreement" to achieve the goal of reducing carbon emission intensity by 60% to 65% by 2030. For this reason, my country has proposed the establishment of carbon tax and carbon trading. A series of policy mechanisms such as the market, and the concept of an integrated energy system provide new ideas for carbon emission reduction. The integrated energy system refers to the integrated system of energy production, supply and marketing generated by the unified and coordinated planning of energy generation, transmission, distribution, conversion, and consumption. In the...

In terms of integrated energy systems, the document "Low-carbon Economic Dispatch of Electricity-Heat-Gas Integrated Energy System Based on Carbon Trading" considers the introduction of step-by-step carbon trading in integrated energy system dispatching, and coordinates comprehensive energy The economy and low carbon of the system, but outsourcing thermal power cannot make the overall system economy optimal

To sum up, it can be seen that at present, the carbon trading mechanism is mainly introduced into the integrated energy system, and the principle of the stepped carbon trading mechanism has not been introduced into the integrated energy system.
