My experience with EthernetIP and CIP was limited to the interaction between VTSCADA and Allen-Bradley PLCs. This experience was amazingly straightforward. The CIP driver built into VTSCADA made me complacent and I assumed that it was going to be just as easy when I got started with it in the SEL-RTAC. It wasn’t The goal […]

The yellow line is PV solar and the […]

Updating Heating Control – Home Micro Grid
This post is all about how I’m updating the current control of the ETS that we installed last November. When it was installed we had the contractor do the least control they could to get going, with the plan that I would upgrade it in the winter. Well COVID happened and that sucked up all […]
Electric Thermal Storage
There is a lot of talk about chemical based energy storage (batteries), but before batteries there was thermal storage. Thermal storage is similar to using bricks or water for thermal mass, it limits the thermal swings by slowly releasing the thermal energy into the space even after the heat source (sun, fire, etc) has gone […]
What is the Point of Common Coupling
I have been working with a couple regulated utilities over the last few years. Neither of these utilities have a lot of small independent power producers (IPPs). There may be a couple of edge cases, or medium sized wind farms, but as a rule they generate all the energy they need. The grid is getting […]
