20.500.12556/DKUM-14828 INOVATIVNE STRATEGIJE VODENJA ZA INTEGRACIJO FOTOVOLTAIČNIH SISTEMOV V RAZDELILNO OMREŽJE INNOVATIVE CONTROL STRATEGIES FOR THE FULL INTEGRATION OF PHOTOVOLTAIR INSTALLATIONS INTO THE DISTRIBUTION NETWORK Ideja za diplomsko delo je nastala ob nastanku evropskega projekta MetaPV, ki predstavlja napredek na razvoju pametnih omrežij ter hkrati predstavlja celovito rešitev za področju integracije obnovljivih virov v že obstoječe omrežje. V delu je podrobneje prestavljena analiza trenutnega stanja izbranega demonstracijskega omrežja, razvoj regulacijskih metod ter postopek izbire parametrov regulacijskega modela. V sodelovanju s projektnimi partnerji so bili predhodnje določeni razvojni scenariji, ki temeljijo na analizi trenutnega stanja. Glavni cilj diplomskega dela, je prestaviti fotovoltaične sisteme kot pomožno sredstvo pri stabilizaciji omrežja. Prav tako je predstavljen podrobnejsi postopek dinamičnih in lokalnih regulacijskih metod. V ta namen so bile izvedene tako analize regulacijskih sistemov in algoritmov kot tudi analize izbire začetnih parametrov regulacijskega modela. Za vse analize je bilo predhodnje uporabljeno programsko okolje Power Factory - DigSILENT®. Pridobljeni rezultati diplomskega dela, bodo kasneje v celoti uporabljeni v nadaljnem razvoju regulacijskih metod in pametnih omrezij, v okvirju evropskega projekta MetaPV. The research investigated new possibilities for the full integration of photovoltaic installations into the distribution network. The thesis aims at investigating the possible impact of distributed generation (DG) on operational and control aspects of distribution network and to propose solutions to limit this impact. For this purpose, a network has been selected in order to perform reality-close investigations. As a main object in this thesis, the different types of voltage control strategies for full integration of DG installations into the existing network have been developed and investigated. In addition to already existing inverters, the new definition of functions for PV inverters for both small (residential) and large (commercial) application is given. First, an overview of the current status in the selected network area is given. Afterwards the impact of DG on the distribution network is described. In a second part the possible impact on the voltage profile, power quality, and voltage stability of the distribution network is investigated with different distribution and load conditions. Finally, from the proposed possible countermeasures, one function has been activated and used for coordinated operation/control without additional communication or superior control. Results are the operational algorithms for the four different types of systems: residential and commercial systems with and without storage respectively.
