摘要/Abstract

摘要： 针对新型含碳捕集热电联产燃气机组的碳利用和经济运行问题，构建其与风电、电转气（power-to-gas，P2G）聚合的虚拟电厂。将所排放的CO₂捕集并输送至P2G，作为电转气的碳原料，产气为燃气机组提供燃料补充，从而在虚拟电厂中实现碳循环利用。以虚拟电厂收益最大为目标，以CO₂捕集率、热电比、热电厂电出力以及电转气功率为决策变量，建立虚拟电厂优化运行模型。仿真结果表明，这种聚合模式的虚拟电厂，可获得更高的经济效益、更好的风电消纳效果、更低的碳排放。这种虚拟电厂及其碳循环利用方式，是一种有效的减少弃风、降低排放、增强碳利用的能源运转途径，具有显著经济及社会效益。

Abstract: Aiming at the problem of carbon utilization and economic operation of the new type of carbon capture and Cogeneration gas unit, a virtual power plant converged with wind power and power-to-gas (P2G) was constructed. The emitted CO₂ was captured and transported to P2G as the carbon raw material for power-to-gas, so as to realize carbon recycling in virtual power plants. The optimal operation model of the virtual power plant was established. The goal was to maximize the benefit of the virtual power plant, and the decision variables were CO₂ capture rate, thermoelectric ratio, electric output of the thermal power plant and electric to gas power. The simulation results show that the virtual power plant in this aggregation mode can obtain higher economic benefits, better wind power consumption, and lower carbon emissions. This virtual power plant and its carbon recycling method are an effective way to reduce wind curtailment, reduce emissions, and enhance carbon utilization. It has significant economic and social benefits.

Key words: gas-power plant carbon capture, power to gas, carbon recycling, wind power consumption, virtual power plant
