本文探讨了利用集中供暖、通风和空调（HVAC）负载提供小时内负载平衡服务的潜力。提出了一种直接负载控制算法。温度优先级列表的方法被用来最佳地分配HVAC负载，以保持客户期望的室内温度和负载多样性。真实的小时内负载平衡信号用于评估HVAC负载在不同室外温度曲线和不同室内温度设置下的操作特性。还调查了所需的HVAC单元的数量。建模结果表明，每天24小时提供±1 MW负载平衡服务所需的HVAC单元数量随基线设置、高温和低温设置以及室外温度而显著变化。结果表明，由HVAC负载提供的小时内负载均衡服务满足性能要求，并且可以成为负载服务实体的主要收入来源，其中双向通信智能电网基础设施能够对HVAC负载进行直接负载控制。
This paper investigates the potential of providing intra-hour load balancing services using aggregated heating, ventilating, and air-conditioning (HVAC) loads. A directload control algorithm is presented. A temperature-priority-list method is used to dispatch the HVAC loads optimally to maintain customer-desired indoor temperatures and load diversity. Realistic intra-hour load balancing signals are used to evaluate the operational characteristics of the HVAC load under different outdoor temperature profiles and different indoor temperature settings. The number of HVAC units needed is also investigated. Modeling results suggest that the number of HVAC units needed to provide a ±1-MW load balancing service 24 hours a day varies significantly with baseline settings, high and low temperature settings, and outdoor temperatures. The results demonstrate that the intra-hour load balancing service provided by HVAC loads meets the performance requirements and can become a major source of revenue for load-serving entities where the two-way communication smart grid infrastructure enables direct load control over the HVAC loads.
