Integrace OZE a EV do elektrizační soustavy

FEKT-BPC-IOEAcad. year: 2025/2026

The paradigm of electricity system (ES) operation with connection and behaviour of users at each level of the distribution system (DS) is changing. The transition can be characterized by: a shift away from central generators in the transmission system (TS) towards the integration of DG in the high voltage (HV) and low voltage (LV) DSs; the integration of BESS and e-mobility assets; and the installation and operation of related technologies and equipment in these systems to meet the sub-economic and technical objectives of DS users. However, this also fundamentally changes the conditions for ensuring and maintaining operability, EMC and VQ at the individual DS and PS levels, as well as in the sub-grids that are community and private networks.

The concepts and operation of ES with attributes of modern power system elements (distributed generation, controlled consumption, battery storage, electromobility infrastructure, etc.) are discussed in the course. In the introduction, the course focuses on describing the characteristics and behaviour of these components and devices, in relevant operating modes and from the perspective of the interface with the AC grid. In the following, the topologies and compositions formed at the distribution/local/community/industrial and private network levels are explained and shown by examples, with the definition of their operational challenges. EMC fundamentals are illustrated theoretically and network scale EMC coordination is demonstrated through voltage quality indicators.  Mathematical modelling techniques are discussed in order to determine the behaviour of system concepts in the power grid. Connection requirements are summarized from both EMC and grid operation support requirements perspectives. Finally, the findings are applied to define the proper system integration of all elements of modern power systems to ensure operability and EMC, both in grid and islanded operation.

Entry knowledge

Knowledge at 2nd year level of electrical engineering, power generation, power distribution, power electronics and electrical machinery and apparatus is required.

Work in the laboratory is subject to a valid 'instructed person' qualification, which students must obtain prior to attending the classes. Information on this qualification is provided in the Dean's Guideline Familiarizing Students with Safety Regulations.

 

Rules for evaluation and completion of the course

The final evaluation of the course is according to the faculty rules. The course completion requirements may be modified as needed by a course guarantor's decree issued prior to the start of the semester.

Scoring consists of the evaluation of partial tests, laboratory exercises and the final examination according to the faculty study rules. Laboratory exercises are evaluated on the basis of readiness for class and submitted reports with a maximum of 32 points, the minimum for the award of credit is 14 points. The evaluation includes a test verifying the acquired knowledge from the exercises, with a maximum of 8 points and a minimum of 4 points for the award of credit. The final examination is written or oral (according to the decree for the year), with a maximum of 60 points, with a minimum of 30 points required to pass.

The final examination focuses on the orientation and knowledge of the structure, composition and characteristics of new era active power systems, with the integration of distributed generation, storage systems and infrastructure for electromobility; the principles, tools and means for ensuring operability and electromagnetic compatibility in these power systems.

The specification of the monitored classes and the way they are carried out shall be laid down in an annually updated decree of the subject guarantor. In general, the classes are optional, except for laboratory training, which is compulsory. Reasonably excused missed laboratory exercises may be made up, if possible, in consultation with the instructor, but during the regular semester.

 

Aims

The objective of the subject is to familiarize students with the operational aspects of integrating distributed generation (DG) - renewable sources (RES) and on-station / on-board battery storage systems (BESS) into distribution / local / community and private grids, in synchronous parallel and islanded operation; and to characterize feasible approaches.

The graduate of this subject is able to:

  • characterize the network characteristics of DG, controlled loads, BESSs, and electric vehicle (EV) charging infrastructure (EVC),
  • describe their basic operating modes and characteristics,
  • enumerate the topologies and specifics of the network infrastructure from the transmission grid to community and private networks,
  • explain the aspects and principles of synchronous parallel and islanded operation,
  • apply the principles of electromagnetic compatibility (EMC) to power systems and relate it to voltage quality (VQ),
  • determine disturbance levels, specify emission limits and know how to ensure EMC,
  • design proper system integration of DG and on-station/ on-board BESS into distribution/ local/ community and private grids.
