摘要
Modem intemet of things technologies bear the promise of cheap, ubiquitous and standard solutions for the smart grid. The end-to-end architecture relies upon transverse service enablement and device connectivity platforms, LTE communications solutions and communication gateways bridge the gap between 3GPP standards and legacy communications solutions. This paper will have a specific focus on the multi-services, multi-protocols gateways that allow connection to legacy assets, and how they are a critical component for the digitalization of power grids and cities. We will illustrate how this gateway--called the Smart Grid Node--has enabled Duke Energy (USA) to initiate its grid modernization project in Cincinnati, Ohio. We will also show that the smart grid node is much more than a communication gateway as it can host very diverse decentralized applications and therefore be a key component to enable multi-services smart city nodes in the near future.
