I Modelling and simulation of electric power grids

The modelling and simulation of electrical power grids is applied in planning and operation process of the power system. It helps in analysis of actual system state and assessment of impacts of future scenarios e.g. integration of RES.

The professional power simulator tools are available to model and determine network parameters. Depending on the required analyses, the real grid has to be represented in the mathematical model. Therefore, model of each element has to be created in detailed or reduced way. To determine network parameters various calculations should be performed which includes:

  • power flow calculations, AC three-phase symmetrical and asymmetrical power flow,
  • identification of resource utilization, node voltages, limits violation, power losses,
  • (n-1) analysis,
  • short-circuit current calculations,
  • simulation of single, multiple or follow failures of equipment,
  • protection calculations,
  • reliability calculation, indices, failure costs vs. investment costs assessment.

II Designing an optimal structure and determining a set of possible configurations of LV microgrids

In RIGRID project algorithms to support the design of optimal structures of newly planned microgrids (selection of microsources, energy storage units, LV power lines and defining a set of possible configurations of microgrid) will be developed. Microgrid structures will be designed primarily for synchronous mode of operation with external distribution grid. In case of failure or disturbance in distribution grid it is allowed to reconfigure microgrid and switch into island mode of operation to cover the demand of customers sensitive to interruptions in the supply of electricity. The design process of optimal microgrid structure will be based on data about particular components of microgrid and customers demand profiles. During the optimal structure design process it should be assumed that all installed microsources and energy storage units are fully operational and capable of satisfying 100% demand of customers. The task of optimal microgrid structure design will be solved by using AI optimization methods.

III Virtual Reality for interactive area and infrastructure planning

Integrated methods of planning, which facilitate intensive stakeholder networking and early involvement of residents affected by a project, hold crucial potential for improvement. Virtual reality (VR) enhances forms of interdisciplinary communication and collaboration, thus responding to the steadily growing complexity of projects. VR technologies efficiently support the phases of planning and development and are even being effectively employed to subsequent operation and maintenance. Photorealistic 3-D models paired with VR work and analysis systems facilitate discussion of plans for infrastructure actions, long before their actual implementation (see Fig. 6). Only well communicated project will be understood holistically by the stakeholders and broadly accepted by residents affected by it.


Future energy infrastructure development will grow in complexity and reflect the increasingly varied basic conditions and the need for interdisciplinary and sustainable solutions. This will affect the intensified and early involvement of all stakeholders (e.g. affected citizens, environmental protection agencies, governments, etc.) in the development processes as well as the establishment of broad acceptance of projects among the public. VR solutions render work methods more effective and generate value added in infrastructure planning, particularly in area of power system.
