现代光伏（PV）逆变器和其他基于逆变器的分布式能源（DER）能够提供具有不同先进逆变器功能的电网支持服务。目前，这些功能对电网运行（包括电压调节、频率备用部署、保护系统和其他辅助服务）的细微影响尚未完全了解。研究人员越来越多地转向硬件在环（HIL）仿真，通过将物理设备耦合到电力仿真来回答可再生能源集成问题。不幸的是，这些仿真通常使用理想的功率转换器模型来表示终端设备。在本文中，我们对多个光伏逆变器产品进行参数表征，以生成经验方程，这些方程准确描述了一系列操作条件下电压无功、固定功率因数和频率-瓦特电网支持函数的逆变器行为。这些方程用于HIL和其他功率仿真，以更好地表示现场设备的实际输出，
Modern photovoltaic (PV) inverters and other inverter-based distributed energy resources (DER) have the ability to provide grid-support services with different advanced inverter functions. At this time, the nuanced influence of these functions on grid operations, including voltage regulation, frequency reserve deployments, protection systems, and other ancillary services is not fully understood. Researchers are increasingly turning to hardware-in-the-loop (HIL) simulations to answer renewable integration questions by coupling physical devices to power simulations. Unfortunately, it is common for these simulations to use ideal power converter models to represent the end-devices. In this paper, we perform parametric characterization of multiple PV inverter products to generate empirical equations which accurately describe the inverter behavior for volt-var, fixed power factor, and frequency-watt grid support functions over a range of operating conditions. These equations are designed for use in HIL and other power simulations to better represent the actual output of fielded equipment,
