论文摘要
柴油发电机是在世界远程区域中发现的远程混合微电网的固有部分，可在负载或生成变化过程中提供主要频率响应（PFR）以恢复系统频率。但是，通过基于逆变器的资源（IBR）集成到微电网中，IBR控制提供了快速频率响应（FFR）以恢复系统频率。因此，用FFR补充PFR需要一个复杂的控制系统和高保真柴油发电机模型来设计这些控制系统。在这项工作中，开发了柴油发电机的高保真模型。它的参数是使用替代优化算法调整的，通过在变化为400 kVa caTerpillar C-15柴油发电机的载荷变化过程中，类似于远程微电网中的响应。柴油发电机模型由同步机，具有V/Hz限制器的DC4B激发以及提议的修改后的IEEE GGOV1 Engine-Governor模型（GGOV1D）组成。将GGOV1D的性能与简单的木质脱水和标准的IEEE GGOV1发动机 - 政府模型进行了比较。结果表明，柴油发电机使用GGOV1D模型对负载变化的响应的误差较低，而在逮捕和回弹期间的频率响应提高了，而频率响应的提高了。
Diesel electric generators are an inherent part of remote hybrid microgrids found in remote regions of the world that provide primary frequency response (PFR) to restore system frequency during load or generation changes. However, with inverter-based resources (IBR) integration into microgrids, the IBR control provides a fast frequency response (FFR) to restore the system frequency. Hence, supplementing PFR with FFR requires a sophisticated control system and a high fidelity diesel electric generator model to design these control systems. In this work, a high-fidelity model of a diesel electric generator is developed. Its parameters are tuned using a surrogate optimization algorithm by emulating its response during a load change to a 400 kVA Caterpillar C-15 diesel generator, similar to those found in remote microgrids. The diesel electric generator model consists of a synchronous machine, DC4B excitation with V/Hz limiter, and a proposed modified IEEE GGOV1 engine-governor model (GGOV1D). The performance of the GGOV1D is compared with simple, Woodward DEGOV, and a standard IEEE GGOV1 engine-governor model. Results show that error in the diesel electric generator's response to load changes using the GGOV1D model is lower with an improved frequency response during the arresting and rebound period than the other engine-governor models.
