Aggregation of Hybrid Dynamical Systems for Demand Response Modeling and Analysis

本研究的目的是为不同需求响应策略下的聚合负荷建模建立理论基础。将建立具有一般非线性子系统动力学的混合系统模型来描述单个负载动力学。研究的主要目的是对各种需求响应场景下不同类型的响应负荷进行统一的抽象。此外，该项目还将开发一个通用的建模框架，以捕获大量异构混合系统的聚合动态。智力优势：该项目是第一个尝试开发一个整体聚合建模框架的项目，该框架可以处理各种响应负载和需求响应策略。它能够以统一的方式解决许多重要的现实挑战。这样的框架是识别和处理聚合负载建模中的基础研究挑战的关键，并且将使需求响应策略的正式分析和设计成为可能。更广泛的影响：需求响应是实现可再生能源在未来电网中高度渗透的关键技术。该项目将为可靠的大规模部署需求响应计划提供基本工具。此外，该项目还将影响一些教育和外展活动，如本科生和代表性不足的学生参与研究，将研究成果纳入课程，高中生的参与。在这个项目中，还将与俄亥俄州哥伦布市的Metro Early College高中建立密切的合作关系。

The objective of this research is to establish theoretical foundations for aggregated load modeling under various demand response strategies. A hybrid system model with general nonlinear subsystem dynamics will be developed to characterize individual load dynamics. The main research thrust is to obtain a unified abstraction for different types of responsive loads under a variety of demand response scenarios. In addition, the project will also develop a general modeling framework to capture the aggregated dynamics of a large population of heterogeneous hybrid systems. Intellectual Merit: This project is among the first that tries to develop a holistic aggregated modeling framework that can deal with various responsive loads and demand response strategies. It can address many important realistic challenges in a unified manner. Such a framework is the key to identify and address fundamental research challenges in aggregated load modeling, and will enable formal analysis and design of demand response strategies. Broader Impacts: Demand response is a key technology to enable high penetration of renewable generations of the future power grid. This project will yield fundamental tools for reliable large-scale deployment of demand response programs. In addition, the project will also impact a number of education and outreach activities such as participation of undergraduate and under-represented students in research, inclusion of research results into courses, involvement of high school students. Close partnership with the Metro Early College High School at Columbus, OH will also be established during this project.
