提出了一种有前途的方法，用于扩展 CERTS 微电网概念的吸引力特征，使其超出其强大的即插即用和自主控制特性，包括集成光伏 (PV) 微源，并减少电网接口的波动性。所提出的 CERTS 光伏微电网采用下垂控制光伏逆变器源和馈线流量控制微源，其稳态和瞬态特性在各种苛刻条件下进行了探索，包括辐照度时变变化、微电网孤岛和负载变化事件。所提出的配置对各种事件表现出良好的瞬态响应，并且能够在所有操作模式下最大限度地收集光伏能量。提供了 CERTS 微电网测试台的模拟和实验结果来验证所提出的方法。
A promising approach is proposed for extending the appealing features of the CERTS microgrid concept beyond its robust plug-and-play and autonomous control characteristics to include the integration of photovoltaic (PV) microsources with reduced volatility at the grid interface. The steady-state and transient characteristics of a proposed CERTS PV microgrid that incorporates a droop-controlled PV inverter source and a feeder flow-controlled microsource are explored under a variety of demanding conditions including time-variant changes in irradiance, microgrid islanding, and load change events. The proposed configuration exhibits well-behaved transient responses for a variety of events, as well as the ability to maximize the harvest of PV energy during all modes of operation. Simulations and experimental results from a CERTS microgrid testbed are provided to validate the proposed approach.
