计及碳市场和绿证市场的配电网投资效益动态评估

随着碳排放权交易机制和绿证交易机制的持续完善，配电网投资效益评估需综合考虑电力市场与碳市场及绿证市场间的交互影响。建立电-碳-绿证市场协同运营架构，剖析碳市场、绿证市场对配电网投资决策的因果反馈关系。从发购电、碳排放权交易、绿证交易、可再生能源消纳责任权重和投资效益5个层面搭建系统动力学子模块，提出计及碳市场和绿证市场耦合关系的配电网投资效益动态评估模型。算例仿真结果表明，所提模型在提高配电网投资效益的同时可减少碳排放以及提高可再生能源消纳责任权重。

Dynamic evaluation of investment benefit for distribution network considering carbon market and green certificate market

With the continuous improvement of carbon emission right trading mechanism and green certificate trading mechanism, it is needed to comprehensively consider the interactive impact among the electricity market, the carbon market and the green certificate market for the evaluation of investment benefit of distribution network. A collaborative operation structure of electricity-carbon-green certificate market is built, and the causal feedback relationship of the carbon market and the green certificate market on the investment decision of distribution network is analyzed. The sub-modules of system dynamics are built from five aspects of power generation and purchasing, carbon emission right trading, green certificate trading, responsibility weight of renewable energy consumption and investment benefit, and a dynamic evaluation model of investment benefit for distribution network considering the coupling relationship between the carbon market and the green certificate market is proposed. The example simulative results show that the proposed model can improve the investment efficiency of distribution network while reducing the carbon emission and increasing the responsibility weight of renewable energy consumption.
