摘要

随着可再生能源和智能电网部署的出现,控制需求以减少电力消耗的可变性,从而减少对监管的需求越来越普遍,负载聚合器现在利用一些电力负载的可延期性来平滑消费概况。本文利用排队理论中的工具分析了服务延迟和调度对电力消耗可变性的影响。我们考虑一个接收作业请求的负载聚合器的通用模型,其中涉及要提供的一定数量的能量和截止日期。我们分析了不同的调度策略,并检查了服务延迟的影响,量化了方差减少和达到最后期限之间的权衡。

Queueing analysis of service deferrals for load management in power systems
With the advent of renewable sources and Smart-Grid deployments, it is increasingly common to control demands in order to reduce power consumption variability and thus the need for regulation, with load aggregators now exploiting the deferability of some power loads to smooth the consumption profile. In this paper, we analyze the impact of service deferrals and scheduling on power consumption variability using tools from queueing theory. We consider a generic model for a load aggregator that receive job requests, involving a certain amount of energy to be provided and a deadline. We analyze different scheduling policies and examine the impact of service deferrals, quantifying the tradeoff between variance reduction and attained deadlines.
