Voltage profile regulation in LV distribution systems by means of OLTC equipped distribution transformer and series transformers based on distributed monitoring data
Tato diplomová práce se zabĂ˝vá Ĺ™ĂzenĂm velikosti napÄ›tĂ v sĂtĂch NN s ohledem na nárĹŻst distribuovanĂ© vĂ˝roby zejmĂ©na pak obnovitelnĂ˝ch zdrojĹŻ energie. Obsahuje rešerši o stávajĂcĂm stavu sĂtĂ nĂzkĂ©ho napÄ›tĂ. Následuje návrh Ĺ™ešenĂ novÄ› vzniklĂ©ho stavu spoÄŤĂvajĂcĂ v nasazenĂ OLTC distribuÄŤnĂho transformátoru a v pĹ™ĂpadÄ› sloĹľitÄ›jšà topologie nasazenĂ sĂ©riovĂ©ho transformátoru napÄ›tĂ, kterĂ© budou součástĂ konceptu Smart Grid. V tĂ©to práci je rozebrána takĂ© problematika měřenĂ a pĹ™enosu dat. Jako druhá část je popis vybranĂ˝ch Ĺ™ĂdĂcĂch strategiĂ a jejich simulace. Pro potĹ™ebu simulacĂ je zde popsán návrh modelĹŻ jednotlivĂ˝ch prvkĹŻ soustavy v prostĹ™edĂ PSCAD. Z tÄ›chto prvkĹŻ byla sestavena testovacĂ sĂĹĄ a na nĂ byly odzkoušeny jednotlivĂ© scĂ©náře simulacĂ.This diploma thesis discusses two major topics. The first one is the control size of the voltage in LV networks in regard to the increase in distributed generation concered to renewable energy sources. The study contains a review focused on the current state of low voltagegrid followed by a proposal for the solution of the oncoming state. The solution is identified as a deploying OLTC distribution transformer. In the case of more complex topology is deployed a series voltage transformer. Both methods are part of the Smart Grid. The thesis also analyzes the issue of the data measurement and data transmission. The second part of the thesis consists of the description of selected control strategies and their simulations. The design of individual system elements in the PSCAD is described. From these elements, a test network was constructed and tested the individual simulation scenarios.
