20.500.12556/DKUM-57125 MODEL MIKRO OMREŽJA Z RAZPRŠENIMI VIRI IN HRANILNIKOM ENERGIJE MODEL OF A MICRO-GRID WITH DISTRIBUTED GENERATION AND ENERGY STORAGE Vpeljava sodobnih rešitev, kot so razpršena proizvodnja, ki temelji predvsem na obnovljivih virih energije in napravah za shranjevanje električne energije ter pameten nadzor in vodenje z uporabo informacijskih in komunikacijskih tehnologij, omogočajo nov pristop k načrtovanju in vodenju električnih omrežij in elektroenergetskega sistema. V tem kontekstu se mikro omrežja pojavljajo kot koncept prihodnosti. Magistrska naloga na nivoju simulacijskih izračunov obravnava mikro omrežje, ki vsebuje porabnike, enote razpršene proizvodnje in sistem za shranjevanje energije. V začetnem delu magistrske naloge so podane osnovne značilnosti mikro omrežja. V nadeljevanju je v programskem paketu MatLab/Simulink sestavljen model mikro omrežja s katerim je izvedeno ustrezno vodenje razpršenih virov in hranilnika energije. V paralelemen obratovanju vodenje mikro omrežja temelji na regulaciji toka, v otočne obratovanju pa je dodana še nadrejena regulacijska zanka za regulacijo napetosti. S simulacijskimi izračuni sta preverjena paralelni in otočni način obratovanja mikro omrežja kot tudi prehodi med obema načinoma. Modern solutions such as distributed generation, mainly based on renewable energy sources, combined with electrical energy storage, as well as smart control and management based on information and communication technologies, enable new concepts in design and control of electricity network and power system. Among these concepts, microgrid aspires to be a concept of the future. The Master Thesis gives an overview of microgrid concept, including distributed generation and energy storage systems. In the first part of the thesis basic features of microgrid are described. The procedure, applied to model the microgrids elements, including control of distributed generators and storage system, in the software package MatLab/Simulink, is presented. The obtained model is used to simulate parallel and island mods of microgrid operation and the transitions between them. The current controller normally used in the parallel mode of operation is upgraded with an additional voltage controller when island mode of operation is applied. mikro omrežje razpršena proizvodnja hranilnik energije regulacija toka regulacija napetosti microgrid distributed generation energy storage current control voltage control true true false [V.
