DSO Toolbox

Toolbox for Distribution
Systems Operators

Scroll Down



The ever increasing penetration of distributed Renewable Energy Systems (DRES) into the Distribution Grid entails significant challenges for the Distribution System Operators (DSOs). Such challenges emerge due to the transition from the traditional architecture whereby power flows from centralized production to the loads at the edges of the grid to a new paradigm whereby bidirectional power flows appear on the lines, due to the presence of DRES. In this context DSOs are in need of novel tools and methodologies that will enable them:

  • To perform cost / benefit analysis regarding the incorporation of different technologies and the adoption of various emerging added-value services into the Distribution Gridmodus operandi;
  • To decide on the technically credible and economically viable operation of the Distribution Grid, especially in light of the presence of a large number of intermittent production units and while operating in island mode;
  • To decide on the composition and functional characteristics of the various types of production units, as well as to the planning, scheduling, operation, supervision and control of the various assets of the Distribution Grid; and
  • To dynamically shape the load-curve in order to respond to the production conditions and dynamic conditions of the Distribution Grid.


The aim of the project is to develop a toolbox that will facilitate DSOs in the fulfillment of their tasks, both in planning and at the operational phase. In particular, the following tools and models will be developed:

  • A tool for techno-economic analysis of the impact of incorporating different technologies and energy services into the Distribution Grid modus operandi;
  • Models for the assessment of the flexibility of operation of the Distribution Grid;
  • Models for spatial electric load forecasting;
  • A tool for the operation of the Distribution Grid at emergency conditions;
  • A tool for power quality monitoring; and
  • An Enterprise Service Bus for information’ and services’ integration and interoperation within the DSO’s IT ecosystem.

Solutions to be developed

The project develops models and tools at three levels:

Expansion and upgrade of the Distribution Grid

Concerns a tool for simulation and techno-economic analysis for planning the expansion and upgrade of the Distribution Grid, by defining new elements of the grid and taking into account the future load increase and the increasing introduction of DRES and storage elements at the Low Voltage grid. Also, development of models for determining the flexibility of the Distribution Grid in the light of future developments (demand response services, p2p trading, etc.) as well as spatially-focused load forecasting models.

Active Management of the Distribution Grid

Tools that facilitate the operation of the Distribution Grid in an emergency situation (e.g. after a permanent fault is detected) and enable real-time monitoring and assessment of the power quality of supply.

Subsystems integration and interoperability with DSO’s IT ecosystem

Concerns the interaction and interoperability of the project’s tools among each other as well as with widely used DSO legacy systems, on the basis of international information and communication standards.

High Level Architecture


WP Structure

The work is divided into 4 work packages (WP):
  • WP1 analyzes the requirements of the DSOs in the area of ​​grid planning, programming, load forecasting and flexibility. In parallel, the specifications of the developed models and tools will be defined along with their implementation details and the reference architecture of the project.
  • In the context of WP 2 & 3 the tools for planning and active management of the grid will be developed.
  • WP4 focuses on the development of the integration mechanism for the outcomes of WP 2 and 3, whilst technical audit and demonstration scenarios will be defined along with key performance indicators. Finally, the tools will be tested and evaluated in laboratory environment.


The project started on July 2018 and has a duration of 3 years.
