The solution includes the following modules:

• ARI grid monitoring: a visualization solution to provide increased insights into low voltage (LV) networks where a large part of new DERs are connecting. Ari is utilizing smart meters and other LV sensor data to solve problems such as voltage violations from rooftop PV, detect outages, reduce losses, and identify fraud (energy theft).

• TATARI grid analytics: a grid modeling and analysis solution building a Digital Twin based on data such as the GIS network model, interval meter data, and historic telemetry (SCADA). The Digital Twin can run powerful power flow-based grid analytics for scenario simulations, new connections process, capacity analysis, loss analysis, and more focusing on identifying congestions and voltage violations and how these can be solved.

• TIA flex management: a grid-aware distributed energy resource management system, which is poised to unlock the full value of DR assets by incorporating real-time distribution network conditions (most DR activations are based on wider-scale conditions). TIA supports multiple ways to access and activate demand side flexibility: via direct DER control, aggregator (aka flexibility service providers) mediated control, and market-based flexibility services. Further, TIA can be configured to calculate dynamic network pricing signals, and to align customer incentives (and DR activations) with grid needs.

• e-TIA DERMS: a DER aggregation platform designed for use by energy retailers and aggregators to enable the provision of flexibility services from end consumers to the distribution grid. Together, e-TIA and TIA provide an end-to-end solution for flexibility management serving both the grid operator and consumer needs.

Further, Plexigrid's solution is not intended to replace legacy tools, such as power flow software for planning (e.g., CYME, Synergi, Powerfactory) or operational technology (e.g., EMS, ADMS, SCADA). Rather, the platform is designed to intake existing data (which is often siloed and difficult to use for complex analyses) and bridge a gap in analytical capability across planning, operations, and customer program teams.

Deployments are offered on a subscription basis (SaaS), based on which modules are selected and the size of the distribution grid.

The Plexigrid technology is built to provide grid analytics for an operational context across organizational silos of the utility. Optimizing distribution grids using DERs and flexible consumers requires the following abilities:

1. Monitoring of low voltage grids, including end consumers and DERs, load and generation forecasting.
2. Near-real-time analytics for simulating both the impact of changes in the grid that affect capacity including new connections, switching, planned outages, etc. as well as how solutions such as energy storage, flexible interconnections or demand response can solve congestions and voltage violations.
3. Calculation of control response to congestions and voltage violations and execution of IoT control commands or publications of control schedules to third parties such as aggregators.

The Plexigrid platform was designed with this holistic operational approach to flexibility in mind from the start adapting analytics and communication to support near real-time performance. It is also capable of managing flexibility through multiple channels including service providers such as aggregators, retailers, and capacity markets as well as direct control of own assets or flexible interconnections.

Plexigrid's software platform is focused on helping distribution utilities (also known as DSOs in Europe) increase their utilization of existing grid infrastructure to manage the fast growth of electrified loads and renewable generation required to meet the goals of the transition to a sustainable energy system. The solution enables demand-side flexibility as an alternative solution to grid reinforcements to increase capacity in a faster, more cost-efficient, and less resource-consuming way. Plexigrid can model the power flows and predict the power demand down to the end consumer and enable the DSO to pinpoint where, when, and how much flexibility is required in the grid. This can be used throughout the life-cycle of the grid from making better investment decisions for grid reinforcements, faster connection of renewables, and activating flexibility resources in grid operations.
