The development of the “Secondary Substation (SS)” as a vehicle that includes operation and control algorithms and functionalities is proposed. These new SS will be able to take advantage of the available information and the communications channels used by meters, RTUs and other devices in an optimized way.
The innovations proposed will be suitable for both the development of brand new SSs and the retrofitting of existing ones thanks to the use of the integration of the energy Box. This Secondary substation will be complemented with the implementation of operation algorithms (fault location and energy supply restoration; e.g., self-healing and grid control) and forecasting algorithms (e.g., demand, generation, pricing) in MV grid, based on the utilization of information provided by IEDs deployed along the grid (SSs, fault detectors, sensors, protections, etc.).
These algorithms, which are housed in operation and planning modules, will be embedded in the FLEXIGRID common platform in charge of processing the data that will be used during the project. In addition to these algorithms, efforts will be made towards de development of a new generation of smart meters with improved Feeder Mapping features, upgrading them with the implementation of these solutions. These smart meters will provide additional information to the Secondary Substations developed by OPA, allowing their algorithms to operate with additional information.
Design and development of an innovative SS able to integrate the different modules previously developed (phase balancing, inverse fault detection, and transformer management) in a single hardware. This SS will be capable of carrying out all the existing functionalities included in (1) the concentrator of measuring equipment, (2) MV protection management, (3) control and communication devices with the head substation and with the rest of SSs of the medium voltage lines; achieving an integrated and optimized management of the grid.
Additionally, the new platform developed throughout the project will integrate a series of toolboxes (control and forecasting algorithms) that will take advantage of both actual and historical data from the IEDs deployed along the grid. Moreover, the new communication protocols will allow to improve the time of response, the autonomous control and the flexibility in the grid. To ensure its replicability, this platform will be compatible with the already existing systems of the different European DSOs, as it will be shown during the demonstration phase of the project.
Demonstration #1, Spain (San Vicente); 4 Substations for the validation of the algorithms and PCTCAN building for the installation of the smart meter.
