The IDE-STATCOM : a Volt/VAR solution based on Idenergy’s inverter technology
The D-STATCOM (“DISTRIBUTED-STATCOM”) from Idenergy is an inverter mounted onto a utility pole that injects or absorbs reactive power in the grid at the secondary of the distribution transformer. As a result, it can provide several services to the grid, such as stabilizing voltage variations and increasing the hosting capacity of the power grid to allow for the installation of more solar PV capacity and electric vehicle chargers.
Volt/VAR curve
A Volt / VAR curve is simply programmed into the inverter according to grid parameters. The curve can be altered remotely through cellular communication. It is also possible to implement additional algorithms for coordinated action between units. To learn more about this feature, visit the Smart Grid section.
Principles
Reactive power is delivered locally at the secondary of the distribution transformer, thus interacting with local transformer inductance and inductive impedance due to spacing between power wires (required for isolation purposes), about 1 mH/km.

Easy installation
Example with a three-phase setup, on triple mount transformer racking
Simulation models for grid integration
Idenergy produces simulation models in order to predict the behavior of the grid and to optimize the use of D-STATCOMs.
Our Matlab inverter models can be used to simulate our D-STATCOMs in an electrical network and see the effects to plan how they should be distributed.
Once installed, by making comparisons with reality, it is possible to derive digital twins from them and integrate them into higher-level intelligence network management systems.
