Abstract
Wired and wireless communications both play an important role in the blend of communications technologies necessary to enable future smart grid communications. Hybrid networks exploit independent mediums to extend network coverage and improve performance. However, whereas individual technologies have been applied in simulation networks, as far as we know there is only limited attention that has been paid to the development of a suite of hybrid communication simulation models for the communications system design. Hybrid simulation models are needed to capture the mixed communication technologies and IP address mechanisms in one simulation. To close this gap, we have developed a suite of hybrid communication system simulation models to validate the critical system design criteria for a distributed solar Photovoltaic (PV) communications system, including a single trip latency of 300 ms, throughput of 9.6 Kbps, and packet loss rate of 1%. The results show that three low-power wireless personal area network (LoWPAN)-based hybrid architectures can satisfy three performance metrics that are critical for distributed energy resource communications.
Highlights
The increasing penetration of distributed Renewable Energy Sources (RESs) and Energy StorageSystems (ESSs), including storage batteries and electrical vehicles, brings new challenges
This paper focuses on simulating hybrid communication architectures to verify the critical system design criteria especially for distributed smart grid applications
The PV data generated at the PV inverter is sent to the smart meter through low-power wireless personal area network (LoWPAN)/power line communication (PLC), and the smart meter relays the packet to the data concentrator through WiFi/WiMAX/Ethernet, which are shown as two black double-arrowed lines on the bottom of Figure 2
Summary
The increasing penetration of distributed Renewable Energy Sources (RESs) and Energy Storage. The monitoring and further control of these leading and emerging RESs and ESSs are progressively pervading modern distribution networks To achieve these goals, the communication infrastructure is required to allow for bidirectional information exchange between distributed generation and storage elements and various levels of the smart grid. Useful insights have been provided in these studies, the existing results cannot be directly extended and applied to practical smart grid communications system design and deployment for the coordination of high-penetration distributed RESs and storage devices. Little attention has been paid to the development of a suite of hybrid communication architecture simulation models to verify the critical system design criteria. To the best of our knowledge, it is the first time hybrid communication simulation models have been created to validate the effectiveness and scalability of hybrid architecture design for distributed smart grid applications.
