摘要

基于虚拟惯性的可再生能源控制有助于提高电力系统的频率稳定性。本文演示了一种基于控制区域网络(CAN)通信的方法，利用商用现成的逆变器来模拟虚拟惯性。这使得目前安装的系统能够以经济有效的方式对虚拟惯性进行改造，从而使电力系统中的RES渗透率更高。概念验证使用Xantrex XW6048混合逆变器/充电器和OPAL-RT实时数字模拟器进行演示。结果表明，基于can的通信可以有效地降低电力系统的频率变化。

Virtual Inertia Emulation using Commercial Off-The-Shelf Inverters

Virtual inertia based control of renewable energy sources (RESs) helps to enhance the frequency stability of power systems. In this paper, a Control Area Network (CAN) communication-based method is demonstrated to emulate virtual inertia using commercial off-the-shelf inverters. This allows the currently installed systems to be retrofitted with virtual inertia in a cost-effective manner which would allow for higher RES penetration in power systems. The proof-of-concept is demonstrated using a Xantrex XW6048 hybrid inverter/charger and OPAL-RT real-time digital simulator. Results show that CAN-based communication can be an effective way to reduce frequency variations in the power system.
