可再生能源电力消纳是实现国家“双碳”战略目标的重要途径。针对区块链技术下政府对电力企业的可再生能源电力消纳动态激励问题，考虑区块链技术在智能合约、能源碳通证和市场信息披露上的应用，同时考虑政府的碳交易政策，运用委托-代理理论分别构建政府在无区块链技术、有区块链技术及区块链技术下考虑碳交易时的动态激励补贴模型，并运用最优控制方法对模型进行求解和分析。研究发现：当电力企业的机会成本大于某一临界点而区块链技术的固定成本小于某一临界点时，区块链技术的实施才有助于提高政府效益；而当电力企业碳减排量的临界值和区块链技术的单位运作成本均较小时，政府在区块链技术下启动碳交易市场才有利。通过数值仿真发现当电力企业的碳减排转化率较高时，政府适当地提高碳交易市场价格是有利的。研究结论可为区块链技术下政府对电力企业的可再生能源电力消纳激励补贴提供一定参考。

Renewable energy power consumption is an important way to achieve the China’s “Carbon Neutrality and Carbon Peaking” strategic goal. However， some regions in China only pursue the scale of wind power installation and economic benefits， ignoring the downstream consumption problem， which affects the sustainable development of the wind power industry. During the 14th Five-Year Plan period， China's new energy will grow substantially， and the average annual new installed capacity may double， and the cumulative installed capacity of new energy will account for 40% in 2030， surpassing coal power to become the largest power source. Therefore， China's renewable energy consumption will face greater pressure and challenges，in this paper， for the government’s dynamic incentive problem for power enterprises' renewable energy power consumption under the blockchain technology. Considering the smart contract， energy carbon token and market information disclosure of the blockchain， as well as the government’s carbon trading policy， and based on the state change of the expected consumption amount of renewable energy， the dynamic incentive subsidy models of the government are constructed by using principal-agent theory， including without blockchain， with blockchain and carbon trading under blockchain. The optimal control method is used to solve the equilibrium solution between the government and power enterprises in different situations， and the optimal dynamic trajectory change law of government incentive strategies are revealed， and the effects of relevant parameters， blockchain technology， and carbon trading policy are analyzed.The results suggest that　（1） Only when the opportunity cost of power enterprises is greater than a certain critical point and the fixed cost of blockchain is less than a certain critical point， the implementation of blockchain can help to improve the benefit of the government. （2） Only when the critical value of carbon emission reduction of power enterprises and the unit operation cost of blockchain are small， it is beneficial for the government to start the carbon trading market under the blockchain technology. （3） Under the government's dynamic incentive subsidy， the optimal dynamic trajectory of the expected consumption amount of renewable energy in different scenarios will increase monotonically over time and then tend to a steady state. （4） Finally， the numerical simulation shows that when the conversion rate of carbon emission reduction of power enterprises is relatively high， it is beneficial for the government to regulate and appropriately increase the carbon trading market price. The results provide good insights for the government to design the renewable energy power consumption incentive subsidy for power enterprises under the blockchain technology.
