Embodiment

[0119] According to the electricity-gas integrated energy system planning method established in the present invention that takes into account the cost of the stepwise carbon transaction, the electricity-gas integrated energy system is planned for a region in 2019-2022. See Table 1 for the calculation coefficients of actual carbon emissions. The carbon trading price is 130 yuan / t, the technical subsidy coefficient is 0.5, the length of the carbon emission range is 40t, and the increase rate of each step of the carbon trading price is 0.3.

[0120] Comparison of the planning results of the three models in Table 1

[0121]

[0122] From the planning results of the three models in Table 1, it can be seen that the model proposed by the present invention has a higher operating cost of CHP units and P2G equipment, and the total cost of the system has increased by 2.169 billion yuan, but the carbon emissions of CHP units are significantly smaller than those of thermal power plants....

Abstract

The invention discloses a gas comprehensive energy system planning method and relates to the field of comprehensive energy system low-carbon planning and the field of power markets. A datum line method is adopted, and compensation-free carbon emission quota of electricity-gas comprehensive energy system is determined according to electricity generated by a thermal power generating unit and a combined heat and power generation unit; an actual carbon emission amount; a technical subsidy coefficient and a carbon emission reduction index are introduced into a carbon transaction cost model to excite the enthusiasm of active energy conservation and emission reduction of a power generation enterprise; the carbon transaction cost is determined according to the no-compensation carbon emission quotaand the actual carbon emission of the gas comprehensive energy system; construction of electricity-to-carbon transaction costs that account for and improve stepwise carbon transaction costs and the gas comprehensive energy system planning model obtains a required planning result according to the model. Establishment of the invention is applicable to electricity-gas comprehensive energy system carbon transaction module, can strictly control the carbon emission of the system and promote low-carbon development of the electricity-gas comprehensive energy system.

Description

technical field [0001] The invention relates to the field of low-carbon planning of integrated energy systems and the field of electric power markets, in particular to a method for planning integrated energy systems considering a carbon trading mechanism. Background technique [0002] With the development of human society, the energy utilization pattern with fossil fuel combustion as the main form has made environmental problems increasingly prominent. The carbon dioxide emitted by the power industry accounts for about 50% of the country's total emissions, which has great potential for carbon emission reduction. The coupling between the electric power system and the natural gas system is deepening day by day, and the traditional mode of independent planning of the electric power system and the natural gas system can no longer meet the needs of the electric comprehensive energy system. The carbon trading mechanism is considered to be an effective means that can balance power...
