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.
