考虑绿证交易的虚拟电厂运行策略优化研究

Operation strategy optimization of virtual power plant considering green card transaction

绿色能源的可持续发展是我国实现3060双碳目标的重要路径,但新能源出力波动大、补贴到位滞后等问题影响新能源发展。绿色证书交易是在市场机制的调节下提升新能源发电收益的有效手段,因此研究绿证交易模式下虚拟电厂的运行优化策略。首先,在购买侧,发电厂商以售电、绿证收益最大为目标,虚拟电厂运营商以购电、绿证成本最低为目标,构建虚拟电厂与发电商之间的主从博弈模型;然后,在出售侧,虚拟电厂运营商以售电、绿证收入最大为目标,用户以综合成本最小为目标,构建虚拟电厂与用户之间的动态博弈模型。最后,采用CPLEX求解器对模型进行求解,通过算例可知,参与绿证交易能够同时扩大发电商利润及虚拟电厂收益,更好地促进了发电商、虚拟电厂运营商、用户之间的合作关系。

Sustainable development of green energy is an important path for China to achieve the 3060 dual carbon target,but problems such as large fluctuations in new energy output and lagging subsidies have affected the development of new energy.Green certificate trading is an effective means to improve the revenue of new energy generation under the regulation of market mechanisms.Operation optimization strategy of virtual power plants under the green certificate trading mode is studied.First,on the purchasing side,power generation companies regard maximizing sales and green certificate profits as the goal,while virtual power plant operators regard minimizing purchase and green certificate costs as the goal,a master-slave game model is constructed between virtual power plants and power generation companies.Then,on the sales side,virtual power plant operators aim to maximize electricity sales and green certificate revenue,while users aim to minimize comprehensive costs,a dynamic game model between virtual power plants and users is constructed.Finally,CPLEX solver is used to solve the model.Examples verify that participating in green certificate trading can simultaneously expand the profits of power generation companies and virtual power plants,and better promote the cooperative relationship between power generation companies,virtual power plant operators,and users.
