本文介绍了使用称为分组能源管理 (PEM) 的自下而上方法协调的多种分布式能源 (DER) 群体的系统分析。特别地，对于建模为双线性系统的分布式能源的聚合，提供了一种简单的离散时间控制律，其在跟踪由区域传输运营商提供的调节信号的同时最大化接受的请求的数量。此外，还提供了持续输入下能量包完成率的机制以及 PEM 标称服务质量 (QoS) 控制器的定义。最后，解决了 PEM 系统的可观测性问题，包括实现扩展卡尔曼滤波器 (EKF)，用于对不同 DER 群体的动态状态进行状态估计。
This paper presents the systematic analysis of a population of diverse distributed energy resources (DERs) coordinated using a bottom-up approach known as packetized energy management (PEM). Particularly, for the aggregation of DERs modeled as a bilinear system, a simple discrete-time control law is provided that maximizes the number of accepted requests while tracking a regulation signal provided by a regional transmission operator. Moreover, the mechanics of energy packet completion rates under persistent inputs and the definition of a nominal quality of service (QoS) controller for PEM are provided. Finally, the observability of the PEM system is addressed including an implementation of the extended Kalman filter (EKF) for state estimation of the dynamic state of a diverse DER population.
