导入碳交易的新能源发电系统调度管理研究——以风电为例

Research on Scheduling Management of New Energy Power Generation System with Carbon Trading:Taking Wind Power as an Example

在“双碳”背景下,发展低碳电力、实现电力调度低碳转型具有重要的现实和战略意义。针对导入碳交易的含风电力系统调度管理问题,本文在传统电力调度模型基础上引入了自适应场景集的鲁棒思想,建立了考虑碳交易与风电接入的两阶段鲁棒优化调度模型。首先,以经济成本为目标函数,且在其中加入惩罚因子以有效应对风电不确定性。其次,将碳排放权作为约束条件限制煤电的碳排放量,设计合作减排模式以促进煤电清洁高效利用,通过初始碳排放权的分配和交易共享碳排放权。再者,进一步优化电力系统的经济成本,分别在静态合作减排和动态合作减排模式下,实现了风险最大化下的经济成本最小化。然后基于仿真结果验证了模型的合理性。最终通过模型确定了合理的风电比例和合适的煤电合作减排模式以应对风电不确定性及碳交易的不可预测性,进而归纳出了低碳电力调度管理策略。本文研究结论可以为相关部门制定“双碳”背景下的电力调度政策提供科学方法与理论支撑,并为检验或评价政策的合理性提供模拟工具。

Under the background of"dual carbon",it is of great practical and strategic significance to develop low-carbon electricity and realize low-carbon transition of power dispatching.In order to solve the scheduling and management problem of wind-containing power system with carbon trading,based on the traditional power dispatch-ing model,this paper introduces the robust idea of adaptive scenario set,and establishes a two-stage robust optimization scheduling model considering carbon trading and wind power access.Firstly,economic cost is taken as the objective function,and penalty factor is added to deal with the uncertainty of wind power effectively.Secondly,the carbon emission right is taken as the constraint condition to limit the carbon emission of coal power,the cooperative emission reduction mode is designed to promote the clean and efficient utilization of coal power,and the carbon emission right is shared through the distribution and trading of the initial carbon emission right.Moreover,further optimize the economic cost of the power system,respectively in the static cooperative emission reduction and dynamic cooperative emission reduction mode,to achieve the economic cost minimization under the maximum risk.Then,the rationality of the model is verified based on the simulation results.Finally,a reasonable proportion of wind power and an appropriate coal-power cooperative emission reduction model are determined through the model to cope with the uncertainty of wind power and the unpredictability of carbon trading,and then the low-carbon power dispatching management strategy is summarized.The research conclusions of this paper can provide scientific methods and theoretical support for relevant departments to formulate power dispatching policies under the**dual carbon"background,and provide a simulation tool for testing or evaluating the rationality of policies.
