为充分发挥虚拟电厂（virtual power plant，VPP）的减排潜力，挖掘清洁能源潜在利润，提出了一个基于二级碳市场与绿证分配制度的源荷低碳经济调度模型。首先，针对VPP内聚合了多种能源设备的集线器，以综合运维成本最小为优化目标；其次，建立基于碳配额交易与拍卖市场的二级碳市场交易体系，模拟源侧多企业共同参与不完全信息博弈；再次，依据碳流理论，将碳排放量与碳流密度结合为碳指标，并建立荷侧绿证分配方法，提高用户购买绿证的经济效益，从而提高绿证价值，使提供绿证的清洁能源企业从中获益。最后，以一个多区域VPP模型为例，对夏、冬两季典型日进行模拟，算例计算结果验证了二级碳市场与绿证分配制度能有效利用市场传导机制提高环保企业收益，鼓励高碳排放企业向低碳转型。

To fully unleash the emission reduction potential of virtual power plant （VPP） and tap into the potential profits of clean energy, a source-load low-carbon economic dispatching model based on the secondary carbon market and green certificate allocation system is proposed. Firstly, aiming at the hub that aggregates various energy devices within VPP, the optimization objective is to minimize the comprehensive operation and maintenance costs. Secondly, a secondary carbon market trading system based on carbon quota trading and auction markets is established to simulate the incomplete information game involving multiple enterprises on the source side. Thirdly, based on carbon flow theory, carbon emissions and carbon flow density are combined into a carbon indicator, and a green certificate allocation method for the load side is established to improve the economic benefits of users purchasing green certificates, thereby enhancing the value of green certificates and benefiting clean energy enterprises that provide them. Finally, a multi-region VPP model is used as an example to simulate typical days in summer and winter. The results of the case study verify that the secondary carbon market and green certificate allocation system can effectively utilize market transmission mechanisms to increase the revenue of environmentally friendly enterprises and encourage high-carbon emitting enterprises to transition towards low-carbon operations.
