INTERPRETER has produced a confidential report, presenting the high-level use cases and data requirements for the 10 applications which will be developed later in the project.

The work presented in this deliverable serve as a starting point of the development of the 10 applications of the INTERPRETER project. By developing the presented use cases, the partners of each task had the opportunity to align their ideas and expectations, as well as describe the overall framework and assumptions that will guide the applications. This fundamental exercise is providing a head start for the work of WP4 and WP5, because many issues that require lengthy discussions and iterations (such as the narrative, the necessary interactions, assumptions, etc.) have been resolved.

The use-case methodology is employed, in order to provide a coherent, high-level description of the different applications and to identify their data requirements. The ten use cases are divided in grid operation and planning applications.

Network operation Application

Main Objective

Detection of Non- Technical Losses

Provides an expert system which quantifies losses at MV/LV transformer level and provides support to system operation staff to locate non-technical losses as fast as possible.

Ancillary Services to the DSO

Manages voltage deviations, phase unbalances and congestion problems taking into account the flexibility of the LV network, in order to extend lifetime of current infrastructure

Stakeholders’ Interactions for DSO Ancillary Service Extension

Describe an information exchange scheme between the actors to guarantee the safe and efficient operation of the system

Predictive Maintenance Strategies for Grid Assets

Minimization of maintenance/ replacement costs, as well as the frequency and duration of grid’s unavailability, by prioritizing the scheduling of each action (e.g. using the standardised CAIDI/SAIFI KPIs)

Grid control optimization and self-healing

Calculates the optimal distribution of load and generation power in the grid, especially after a fault has been cleared.

The target is getting back to normal operation as soon as possible, minimizing technical losses, curtailment, and ensuring power quality to customers


Network planning Application

Main Objective

Optimal Reactive Power Compensation (ORPC)

Optimised selection of reactive power control elements and its location based on network models

Planned Phase Balancing

Provides different solutions to obtain improved phase balancing, based on network models

Nodal Capacity Allocation

Maximize integration of DER units at nodal level, ensuring safe system operation conditions

Optimal Sizing and Siting of Energy Storage

Sizing and siting of energy storage solutions in grids and consider these as alternative to traditional grid planning investments

Environmental and Economic Performance Analysis and Computation

Environmental and economic analysis of the current and planning grid structure will be studied. Comparative analysis will be presented based on specific and global applied grid performance indicators.  All necessary outcomes will be provided to the DSOs, based on life cycle analysis principles
