考虑风电消纳的含P2G-CCS虚拟电厂优化调度

针对热电联供（CHP）运行过程中产生大量CO2以及“以热定电”运行方式导致的弃风问题，提出一种考虑风电消纳的含电转气和碳捕集系统（P2G-CCS）虚拟电厂优化调度方案。首先，在虚拟电厂（VPP）中引入P2G-CCS耦合模型，并使其与CHP能源流动形成循环，将CO2作为CHP的燃料来源；其次，在VPP中加入地源热泵（GSHP），与P2G-CCS协同运行，实现CHP的热电解耦，促进风电消纳；最后，将电、气综合需求响应引入负荷侧，进一步促进风电消纳。以华北某地区VPP为例进行算例分析，结果表明所提调度方案可以有效促进风电消纳，同时碳排放和运行成本也更低。

Optimal Scheduling of Virtual Power Plants With P2G-CCS Considering Wind Power Consumption

A large amount of carbon dioxide is produced during the operation of combined heating and power （CHP）， the operation mode of "ordering power by heat" will result in wind curtailment. An optimal scheduling scheme of virtual power plant containing P2G-CCS considering wind power consumption is proposed. Firstly，the coupling model of power to gas and carbon capture system （P2G-CCS） is introduced into virtual power plant （VPP）， and let it form a cycle with the energy flow of CHP，CO2 is used as the fuel source of CHP. Secondly，ground source heat pump （GSHP） is added to VPP to operate cooperatively with P2G-CCS to realize thermoelectric decoupling of CHP and promote wind power consumption. Finally，the integrated demand response of electricity and gas is introduced into the load side to further promote wind power consumption. Taking VPP in a region of North China as an example，the analysis results show that the proposed scheme can effectively promote the consumption of wind power，and the carbon emission and operation cost are also lower at the same time.
