论文摘要
电力系统正在向低碳非同步发电组合进行转换。系统规划人员和运营商的主要关注点是可再生渗透未来的系统动态。由于系统的规模和所涉及的许多组件，因此很难根据实际的电力系统模型开发高的PV动态模型。本文的主要贡献是提供一个基于实际大规模电网的验证的动态模型 - 美国东部互连系统的验证动态模型。通过优化实现了传统发电机的位移。将PV分布优化和经过验证的动态模型信息结合起来，这种方法避免了传输计划带来的不确定性。由于可以通过测量来验证现有的动态模型，因此这种方法提高了高PV模型在表示未来电网方面的信誉。这种通用方法可以应用于为其他实际大型系统开发高的PV动态模型。
Power systems are undergoing a transformation toward a low-carbon non-synchronous generation portfolio. A major concern for system planners and operators is the system dynamics in the high renewable penetration future. Because of the scale of the system and numerous components involved, it is extremely difficult to develop high PV dynamic models based upon actual power system models. The main contribution of this paper is providing an example of developing high PV penetration models based on the validated dynamic model of an actual large-scale power grid - the U.S. Eastern Interconnection system. The displacement of conventional generators by PV is realized by optimization. Combining the PV distribution optimization and the validated dynamic model information, this approach avoids the uncertainties brought about by transmission planning. As the existing dynamic models can be validated by measurements, this approach improves the credibility of the high PV models in representing future power grids. This generic approach can be applied to develop high PV dynamic models for other actual large-scale systems.
