DEPsys Smart Grid Active Network Management Solutions

DEPsys provides industry-leading smart grid technology platforms for traditional power distribution networks.

The company develops GridEye hardware and software, which offers digitalisation, visibility, analytics, optimal control, and planning management capabilities. The technology provides an end-to-end active network management solution for operators to manage distributed energy resources (DER) integration and system stability. It also has the capacity to handle additional functionality for grid operations and design.

Smart grid data management for the power industry

GridEye features dedicated field devices for decentralised remote measurement and control. It has a central head-end system for data management and visualisation, communication protocols to link all points, and a large set of applications to generate measurement data values.

The solution can be used in existing distribution grids and supports regional energy networks.

GridEye can be used without prior grid parameter or topology information, while a manual database configuration or link to a geographic information system (GIS) is not required for grid automation. ModelLess® Technology is a useful solution for advanced applications.

Low and medium voltage measurement systems

The first step towards a smarter grid is to increase the visibility of the grid conditions in real-time. In addition to direct high-resolution measurements and alarm functions for low-voltage grids, GridEye calculates the medium-voltage values at the secondary substation level and adds them to a medium-voltage state estimation algorithm. GridEye serves all distribution system voltage levels, delivering high value and cost synergies.

The second step is grid behaviour analysis. Instant or long-term measurement data provides a detailed view of bottlenecks and available capacity. In-depth power quality analysis offers flickers, voltage and current harmonics, rapid voltage changes, as well as other power quality issue information.

GridEye automatically generates power quality reports. The synchronised nature of measurements allows for an accurate comparison of values at different points of the local grid.

Network management solutions for effective grid-hosting capacities

Where most planning software relies on static database data, network models and estimations, GridEye delivers data-driven indications of grid-hosting capacity in terms of possible additional generation and load values at each node.

The simulation functionality provides the estimated impact of an additional DER on the local grid based on real measurement data, delivering more credible outcomes and effectively increasing grid-hosting capacity.

Real-time network assessment technology for decentralised generation systems

One of the biggest challenges during energy transition is handling large numbers of decentralised generation systems such as PV installations and EV chargers. These systems put a significant strain on the distribution grid and prevent a stable operation.

GridEye assesses the network conditions in real-time and arranges advanced algorithms. This enables controllable DERs to reach a good balance between production and consumption, while managing generation, controllable loads, as well as energy storage systems.

Using GridEye, power distribution networks are manageable and allow integration of more DERs without expensive network reinforcement. This produces significant savings for distribution service operators (DSO) and consumers.

Fault identification, localisation and transformer ageing analysis

Intelligent, local algorithms and high-resolution real-time data from distribution grids detect and localise earth faults, as well as 2 or 3 phase errors in low and medium voltage grids. This significantly reduces time-to-repair and system average interruption duration index (SAIDI) values.

Transformer loading and temperature measurements are used to calculate the plant’s expected lifecycle according to the IEC ageing model. A risk-based analysis matrix containing failure probability and impact severity allows for targeted transformer replacement plans.

Further energy optimisation and scheduling are possible with GridEye. This can include the integration of external third-party systems via the central GridEye head-end system.

Local grid topology calculation technology

Based on measurement values and using the patented ModelLess® Technology, GridEye calculates the topology of a local grid within a short timeframe. This is a valuable application for grids with uncertain topologies and for those operating with several configurations where the state of switches heavily influences the stable operation and control algorithms.
