论文摘要
本文为需求侧资源(例如电热水器)提供了一种新型的频率响应控制方案。依赖频率的控制法旨在以完全分散的方式从分布式能源资源(DERS)提供阻尼。该局部控制策略代表每个DER的频率依赖性阈值,以确保汇总响应在频率偏差期间提供阻尼。提议的分散策略基于基于数据包的DER协调方案的改编,其中每个设备向聚合器发送了能源访问请求(也称为“能量数据包”)。然后,可以使用先前接受的活动数据包的数量A-Priori来形成动态功率系统中DER Fleet总体阻尼功能的在线估计。一个简单的两个面积电源系统用于说明和验证分散的控制政策的性能以及在线阻尼的准确性40万台车队的估计。
This paper presents a novel frequency-responsive control scheme for demand-side resources, such as electric water heaters. A frequency-dependent control law is designed to provide damping from distributed energy resources (DERs) in a fully decentralized fashion. This local control policy represents a frequency-dependent threshold for each DER that ensures that the aggregate response provides damping during frequency deviations. The proposed decentralized policy is based on an adaptation of a packet-based DER coordination scheme where each device send requests for energy access (also called an "energy packet") to an aggregator. The number of previously accepted active packets can then be used a-priori to form an online estimate of the aggregate damping capability of the DER fleet in a dynamic power system. A simple two-area power system is used to illustrate and validate performance of the decentralized control policy and the accuracy of the online damping estimating for a fleet of 400,000 DERs.
