水风光互补系统碳电打捆交易技术及闭环回购策略

Carbon Electricity Bundled Transaction Technology and Close loop Buyback Strategy for Hydro Wind Solar Complementary System

摘要:

文中提出了一种发电企业碳电打捆交易技术及闭环回购策略,并提出了发电企业与用户之间通过签订“中长期电量+附加CCER（国家核证自愿减排量）”的合约交易模式，形成发电企业与用户之间的碳电打捆交易与闭环回购模式。同时，计入电力现货市场和碳市场，发电企业和用户均可以在碳电市场中出售电力或CCER提升其经济性。进一步以水风光互补系统为例，建立了一体化电站碳电市场交易效益评估模型和用户成本评估模型。最后，通过算例仿真，分析了水风光互补系统中长期市场和现货市场下的碳电综合效益，并评估了该碳电交易模式下的用户侧经济性成本。所提方法可以在增加发电企业综合收益、降低用户成本的同时，推动可再生能源消纳，促进电力市场与碳市场的协同发展。

Abstract:

A carbon electricity bundled transaction technology and closed loop buyback strategy for power generation enterprises are put forward. The contract transaction mode of "medium and long term electricity quantity + additional CCER(Chinese certified emission reduction)" between power generation enterprises and users is proposed, and the carbon electricity bundled transaction and closed loop buyback mode between power generation enterprises and users have been formed. At the same time, taking into account the electricity spot market and carbon market, both power generation enterprises and users can sell electricity or CCER in carbon electricity market to improve their economy. Taking the hydro wind solar complementary system for example, the trading benefit evaluation model and user cost evaluation model of carbon electricity market for integrated power stations are established. Finally, the comprehensive carbon and electricity benefits of hydro wind solar complementary system in middle and long term market and spot market are analyzed through an example simulation, and the economic cost of user side under the proposed carbon electricity transaction mode is evaluated. The proposed method can not only increase the comprehensive income of power generation enterprises and reduce the cost of users, but also promote the absorption of clean energy and the coordinated development of electricity market and carbon market.
