含碳-绿色证书联合交易机制的综合能源系统日前优化调度

随着能源互联和低碳电力的持续推进,综合能源系统(IES)将成为节能减排的重要载体.结合碳排放权交易(CET)和绿色证书交易(GCT)机制,提出含碳-绿色证书联合交易机制的IES优化运行模型.在分析CET和GCT机制的基础上,搭建碳-绿色证书联合交易市场框架,打破传统碳和绿色证书市场交易的壁垒;综合考虑IES的购电成本、购气成本、设备运行维护成本,建立考虑条件风险价值的碳-绿色证书联合交易模型,并将其引入IES运行优化模型中.算例结果表明:在IES中考虑CET和GCT机制具有较高的经济性与可行性,可提高可再生能源消纳率并减少系统碳排放量.

Day-ahead optimal scheduling of integrated energy system with carbon-green certificate coordinated trading mechanism

With the continuous advancement of energy interconnection and low-carbon electricity, IES(Integrated Energy System) will become an important carrier for energy conservation and emission reduction. Combining CET(Carbon Emission Trading) and GCT(Green Certificate Trading) mechanism, an optimal operation model of IES containing carbon-green certificate coordinated trading mechanism is proposed. A market framework of carbon-green certificate coordinated trading mechanism is constructed based on the analysis of CET and GCT mechanism, which breaks the barriers of traditional carbon and green certificate market trading. Comprehensively considering the electricity purchasing cost, gas purchasing cost and device operation and maintenance cost of IES, a carbon-green certificate coordinated trading model with conditional value at risk is built, which is introduced into the operation optimization model of IES. Case results show that it is of high economy and feasibility to consider CET and GCT mechanism in IES, which can increase the consumption rate of renewable energy and reduce system carbon emission.
