Modeling and Control of Multi-Source Wind, Photovoltaic, and Fuel Cell Distributed Generation Systems

摘要为了评估和改进多电源风光电池分布式发电系统的性能，提出了对多电源风能/光伏/燃料电池分布式发电系统进行建模和控制的研究。将开发所涉及的不同发电设备(即风力发电机、光伏阵列、蓄电池和燃料电池)的适当动态模型。将重点研究质子交换膜(PEM)燃料电池的电学特性，以探索其动态行为，并设计控制器以提高其响应和效率。将整合不同发电设备的动态模型，形成多源分布式发电模型，并探讨其动态性能。基于这种动态响应，将设计一个暂态分类器来管理来自不同发电源的潮流，以提高系统的整体效率和可靠性，并对单电源和多电源系统的经济效益进行评估。

Nehrir, M. HashemAbstractIt is proposed to explore modeling and control of multi-source wind/photovoltaic (PV)/fuel cell distributed generation systems to evaluate and improve their performance. Proper dynamic models of different generation devices (i.e., wind generator, PV arrays, storage batteries and fuel cells) involved will be developed. Special attention will be put on studying the electrical characteristics of proton exchange membrane (PEM) fuel cells for applications such as electric motor starting, load switching and/or rejection to explore their dynamic behavior and design controllers to enhance their response and efficiency.Dynamic model of different generation devices will be integrated to form a multi-sourced distributed generation model whose dynamic performance will also be explored. Based on this dynamic response, a transient classifier will be designed to manage power flows from different generation sources with the objective of increasing the overall system efficiency and reliability.Economic benefits of both single-source and multi-source systems will also be evaluated.
