Abstract
The power industry’s participation in carbon trading and green certificate trading is an effective market-based approach to solve the negative externalities of power production. In this paper, the Virtual power plant (VPP) is taken as the aggregator to coordinate and optimize the carbon trading and green certificate trading between the power purchasing end and the power selling end, so as to achieve the goal of maximizing the comprehensive benefits of the VPP. Firstly, the operation model of VPP aggregating various types of distributed energy and different users participating in green certificate market and carbon trading market is analyzed; Secondly, a two-level collaborative optimization model of VPP participating in power purchase and sale transaction and green certificate transaction is constructed. On the one hand, the cost of power purchase and green certificate acquisition is minimized by combining various types of power generation resources at the power purchase end. On the other hand, the power purchased is distributed among various types of users at the power sale end, so as to maximize the power sale income and green certificate sales income. On this basis, the VPP as a whole participates in the electric energy market, carbon trading market and green certificate trading market to maximize the comprehensive income. Finally, a VPP is taken as an example to verify the economy and effectiveness of the proposed model in this paper.

In order to promote the sustainable development of wind and solar energy and other new energy industries, the government began to try out the Tradable green certificate (TGC) and carbon emission trading system [3]

Based on the VPP's operation mode of participating in the green certificate market and carbon trading market, this paper proposes a collaborative optimization model for VPP to participate in internal power purchase and sale transactions and green certificate transactions, and a decision-making optimization model for external multimarket coordination
Summary
With the continuous improvement of the scale of wind and solar power integration, problems such as low consumption rate of renewable energy power generation and increasing financial pressure of the government began to appear. In order to promote the sustainable development of wind and solar energy and other new energy industries, the government began to try out the Tradable green certificate (TGC) (hereinafter referred to as "green certificate") and carbon emission trading system [3]. Carbon emission rights trading treats excess carbon emissions as commodities, and while restricting carbon emissions through the quota system, it uses market means to improve the competitiveness of low-carbon industries and promote the development of renewable energy power generation [5]
