Controlling Dist. Energy Resources with Edge Computing
summary
SP Digital builds a custom IoT gateway hardware and OS plus a cloud control plane that deploys containerized apps to edge devices; apps are mostly written in Go and shrink to 10 MB Go containers versus 80 MB Java images. Three app types run on devices: data collection, remote control (e.g. Modbus over TCP to curtail PV inverters) and local intelligence for islanded microgrids. System uses gRPC for cloud-agent control, a persistent queue and goroutines for reliable publish, and already runs in rooftops, substations and Changi T3.
