摘要
分布式能源资源的复杂、异构、海量、随机等特点为运行模拟带来了巨大挑战。文章基于数字孪生思想,系统地提出了DER的通用数字孪生体构建与模拟方法。首先基于功率分解思想提出了DER通用稳态模型和暂态模型;然后提出了基于通用模型的DER数字孪生体运行模拟方法。通过算例测试表明,所提方法的有效性,能够实现各类DER运行模拟和预测,为实际电网调度提供参考,有利于促进可再生能源消纳和系统优化运行等。
The complex, heterogeneous, numerous and random characteristics of distributed energy resources(DER) have brought great challenges to the simulation and the operation. Based on the idea of digital twin, this paper systematically proposes a general digital twin modeling and simulation method of DER. Firstly, based on the idea of power decomposition, the general steady-state model and transient model of DER are proposed. Then, the operation simulation method of DER digital twin is developed based on the general models. Finally, the numerical tests indicate the effectiveness of the proposed method, which can realize the operation simulation and the prediction of various kinds of DERs. This work can provide a reference for the actual power grid dispatching and is conducive to promoting the renewable energy consumption, the system optimization operation,etc.
