| 摘要实现电力系统自动需求响应的高速窄带电力线通信(high-speed narrowband power line communication, HNPLC)系统亟需实用、高效的应用层设计来支撑各类响应服务。该文面向自动需求响应服务, 定义了双向互动的HNPLC应用层协议架构, 并结合系统的多分类服务需求, 提出一种综合考虑数据包优先级权重、数据包传输效率和服务等待时间的基于动态优先级的应用层服务响应机制。在构建的跨层HNPLC仿真平台中验证了协议架构的合理性, 且计算机仿真结果表明, 提出的基于动态优先级的服务响应机制可明显提升HNPLC传输性能, 满足自动需求响应的服务要求。 | |||

| Abstract：High-speed, narrowband power line communications (HNPLC) need effective application layers to control the power system demand response to support various services. This study defines an application architecture for an interactive HNPLC system to support automated demand response. The multi-class service demand is provided by a dynamic priority that considers the data packet priority weights, packet transmission efficiency and service waiting times. The service response mechanism, the core of the application layer, is based on the dynamic priority. The application layer is within the cross-layer HNPLC nodes in a simulated practical HNPLC network. Simulations show that the architecture is efficient and the service response mechanism improves the HNPLC performance for the automated demand response. | |||
