使用分布式能源（DERs），如恒温控制负载（tcl），电动汽车（ev）和能源存储系统（ess）作为管理需求的一种方式已经知道了几十年。明确考虑单个DER的本地服务质量（QoS）的需求管理方案称为需求调度。分组能量管理（PEM）是一种需求调度范例，它借用了无线通信中基于分组的概念，通过小型、离散的固定持续时间/固定功率的能量分组，实时动态地管理大规模的DER。PEM通过协调器授权/拒绝来自DERs的传入请求以消耗能量包，以自下而上的方式解决QoS问题。本文扩展了先前对在PEM范式下运行的同质tcl和ess的大规模种群（即宏观模型）建模的工作。特别是，我们扩展了宏观模型方法，以包括可延迟负载（dl），如电动汽车，以及对QoS保证的分析。将基于智能体的（微观模型）仿真与提出的宏观模型进行比较，验证建模精度和QoS保证。
Using distributed energy resources (DERs), such as thermostatically controlled loads (TCLs), electric vehicles (EVs), and energy storage systems (ESSs) as a way to manage demand has been known for decades. A demand management scheme that explicitly considers the individual DER's local quality of service (QoS) is known as demand dispatch. Packetized energy management (PEM) is a demand dispatch paradigm that borrows packet-based concepts from wireless communications to dynamically manage fleets of DER at-scale and in realtime via small, discrete fixed-duration/fixed-power energy packets. PEM addresses QoS in a bottom-up fashion by having a coordinator authorize/deny incoming requests from DERs to consume energy packets. This manuscript extends prior work on modeling a large-scale population (i.e., macro-model) of homogeneous TCLs and ESSs operating under the PEM paradigm. In particular, we extend the macro-model methodology to include deferrable loads (DLs), such as EVs, together with analysis of QoS guarantees. Comparisons between an agent-based (micro-model) simulation and the proposed macro-model are presented to validate modeling accuracy and QoS guarantees.
