我们提出了一个框架来设计分布式能源（DER）的合成惯性和下垂控制参数，以便由 DER 和同步发电机组成的网络中的系统频率符合规定的瞬态和稳态性能规范。我们的方法基于二阶集总参数模型，该模型捕获具有惯性和下垂控制的同步发电机和频率响应分布式能源的动态。这种降阶模型的一个关键特征是其参数可以与原始高阶动力学模型的参数相关。这使得人们能够利用二阶系统的经典频域响应特性来系统地设计 DER 惯性和下垂控制系数。时域仿真验证了模型简化方法的准确性，并演示了如何设计 DER 控制器以满足稳态调节和瞬态性能规范。
We propose a framework to engineer synthetic-inertia and droop-control parameters for distributed energy resources (DERs) so that the system frequency in a network composed of DERs and synchronous generators conforms to prescribed transient and steady-state performance specifications. Our approach is grounded in a second-order lumped-parameter model that captures the dynamics of synchronous generators and frequency-responsive DERs endowed with inertial and droop control. A key feature of this reduced-order model is that its parameters can be related to those of the originating higherorder dynamical model. This allows one to systematically design the DER inertial and droop-control coefficients leveraging classical frequency-domain response characteristics of second-order systems. Time-domain simulations validate the accuracy of the model-reduction method and demonstrate how DER controllers can be designed to meet steady-state-regulation and transient-performance specifications.
