摘要(Abstract)：

为充分调动虚拟电厂各小水电资源协同运行，提高运行可控性，减少碳排放，提出一种考虑小水电时空耦合特性的虚拟电厂低碳运行策略。首先，基于节点参数建模的电网络理论，提出表征多个水电站间时空耦合特性的矩阵集合，便于信息的高效存储和便捷调用。其次，以考虑运行方式调节因子的虚拟电厂日前等效碳排放量为目标，构建考虑时空耦合特性的虚拟电厂小水电低碳运行模型，通过聚合小水电的协同调度，实现各水电站库容调节能力的共享。最后，采用浙江省某县域小水电作为算例，验证所提方法的有效性和实用性。
To fully mobilize small hydropower resources in the virtual power plants to operate collaboratively,improve operational controllability,and reduce carbon emissions,a low-carbon operation strategy of virtual power plants(VPPs)considering the spatiotemporal coupling characteristics of small hydropower is proposed. Firstly,based on the network theory of node parameter modeling,a matrix collection characterizing the spatiotemporal coupling characteristics among multiple hydropower plants is proposed to facilitate efficient storage and convenient recall of information. Secondly,a low-carbon operation model of VPPs considering the spatiotemporal coupling characteristics is constructed with the objective of their day-ahead equivalent carbon emissions that take account of the regulation factor of the operation mode. The sharing of each hydropower plant's reservoir capacity regulation is realized through aggregating coordinated scheduling of small hydropower. Finally,a small hydropower plant in a county of Zhejiang is used as an example to verify the effectiveness and practicality of the proposed method.
