Grid-Expander-Cost-effective solution for the non-firrm grid connection of Low voltage generators

Cost-effective solution for the non-firm grid connection of Low Voltage Generators

capex-free, Faster and cheaper connections to the LV grid

Extra room for low-voltage generators… CAPEX-free!

Our vision is simple.
Faster and cheaper connections to the LV grid for small-scale generators thanks to our unique smart-meter-based LV grid supervision and control technology: Grid ExpanDER.
Sure, Distributed Energy Resources Management Systems are everywhere nowadays. However, most solutions on the market require dedicated hardware and telecommunications, as well as almost-constant human supervision. Such costly solutions are thus suitable only for specific applications, and inadequate for mass deployment. Reusing the smart metering infrastructure makes a world of difference, turning non-firm LV grid connection into an economically viable solution, network-wide!

A pratical solution that results
from years of Research,
Development and validation

Not only did we work hard on turning our Grid ExpanDER concept into reality: for validation purposes, we also had to develop a full laboratory test platform which reproduces the physics of a real low voltage grid!
And now that our product successfully went through in-depth lab testing, it’s ready for the next step: real-world pilot deployment!

pratical-solution: Grid Expander

How it works:

Cruise control for small-scale generation

1

 

Smart meters monitor the grid

3

 

Power reduction setpoints are sent back to smart meters

2

A central controller consolidates measurements and makes curtailment decisions

5

 

The process also applies to flexible loads instead of PV inverters

4

 

Power inverters reduce their output accordingly and relieve the grid

Practical

Grid ExpanDER implements a no-nonsense version of DER flexibility, that does not require complex market design nor the centralized supervision by grid operators of a gazillion of individual small-scale assets.

Cost-effective

Grid ExpanDER reuses the advanced metering infrastructure, eliminating the need for any additional hardware deployment on the grid: in effect, Grid ExpanDER makes non-firm LV connections CAPEX free!

Efficient

Grid ExpanDER usually increases the hosting capacity by tens of percents, while eliminating or deferring the need for grid reinforcement and drastically reducing connection delays.
