TATARI is a grid analytics tool for distribution network planning and operation. Tatari gives you the power to run real time simulations of the past, current and future state of the grid and helps you:
- Understand available capacity
- Optimize investment planning
- Support grid development plans
- Speed up connection requests
- Reduce losses

Power Flow
Power-Flow takes all the topology data from your GIS systems (location and electrical characteristics of every line and node in the network, transformers, switches, fuses, meters, gateways, hubs, etc…), and all the real time measurements from your smart meters and your SCADA system and…voilà! Power-Flow calculates instantly the voltages, currents, loads and power-flows of every line and node in your network, all the way down to 220V!

Fraud Detection
Despite the progress in digitalization and the control of electricity networks, there are still consumers who connect to the network illegally, without a meter, and “steal power” from the electricity grid. Without complete real time visibility under 20 kV, finding fraud among millions of consumers in the network is, for the DSO, like ” finding a needle in a haystack”. Finding this needle requires knowing at all times what happens at each point of the network in terms of power flows, to calculate “transmission electricity losses” and separate them from “commercial loses” or fraud. Our fraud detection algorithm does all of this for you and identifies inconsistencies in your networks that indicate where and when these frauds take place.

Low Voltage Loop Detector
This app identifies unwanted rings in the distribution network as well as other common faults and data inconsistencies. The root cause of these problems usually happens when a field team goes out to the network to carry out work and they make a mistake in uploading the latest status data into the GIS system (e.g. they report in the GIS system that a certain switch is open when in reality it is closed). While some of these can be detected right away and corrected immediately, some can go unnoticed for months or years, creating unwanted effects in the network that become very difficult to identify and correct by DSO engineers.

Phase Classifier
Most residential customers are conneted at 220V between phase and neutral within a four wire 400V three-phase system. Not all utilities have documented to which phase the customers and smart meters are connected. This app helps utilities to create an inventory of what is exactly connected between each pair of phases in each of the three-phase lines.
Tatari
Loss Minimization
Obtain the best configuration of your network to minimize loss, transfer load from overloaded power transformers to underutilized ones using the low voltage network configuration and also the medium voltage grid.
Increase the efficiency of the system, reduce the voltage drops and improve your quality allowing higher penetrations of flexible technologies like electric vehicles, heat pumps or renewable energies combined with energy storage technologies.

Digital Twin Generator
Generate automatically digital twins of your entire network or portions of it.
A digital twin of the electrical system allows not only to have a replica of the actual physical assets, but to simulate different scenarios of the future based in today´s real information. Easy projections and impact analysis of different technologies like distributed generation, EV charger, heating or cooling loads,…
Do you plan to expand the network in that neighborhood? Or do you plan to upgrade that street that require more capacity? What will the implications be in the rest of the network? With the Digital Twin you will be able to assess in advance any consequences of future expansions of upgrades of the grid.

Discover the Power of Knowing.
Instead of making general upgrades based on aggregated information at transformer or substation level, DSOs can now focus their upgrade efforts solely on the bottlenecks of the network, saving millions of euros on unnecessary capacity upgrades. This “bottleneck management“ philosophy has been applied in the manufacturing industry since the late 60s saving them hundreds of billions of dollars in CAPEX that were no longer needed to achieve the same capacity expansion outcomes. However, this “de-bottlenecking” philosophy has not been applied consistently in DSO networks due to its sheer complexity.
A normal DSO network has millions of nodes and lines and can have tens, hundreds or thousands of potential bottlenecks. These bottlenecks, shift from location to location from one time to another as cities busily tick away through days, weeks and seasons …
This application allows DSOs to understand where their bottlenecks are in the network, when, why and how they are formed and which are the underlying consumer/producer nodes that are contributing to the formation of these bottlenecks.
Tatari - Power Flow
Why hasn’t instant Power-Flow computing been available for DSOs before?
The math and computing capacity to resolve the power flow problem in high voltage networks consisting of hundreds of nodes is “relatively simple” and has been around for decades. But in low voltage networks, hundreds of nodes become millions of nodes and low voltage networks are “unbalanced, 4-wire networks” as opposed to the simpler “balanced, 3-wire HV networks”. This complicates the problem exponentially. The same algebra and algorithms that resolve the high voltage networks power flows in seconds, take days to resolve in multimillion node low voltage networks. If such calculations are to be used for real time demand response purposes… a two days latency, simply doesn´t work.
Compute Power-Flows in your entire network… in just two seconds!
The Plexigrid team has invested over 7 years of research efforts to develop the right algebra and the right data structuring, the right computing setup, and the right state estimation and power-flow algorithms to resolve the calculation of power flows in just under 1 second! fast enough to act before an overload triggers a switch or blows a fuse, not too bad! Plexigrid has achieved these results in real electricity networks with millions of nodes and lines.
