Increasing integration of dispersed, renewable energy sources, fast changing energy flows and lack of flexibility resources for voltage regulation in the power grid, lead to unacceptable voltage states. With the aim of improving voltage regulation and grid stability, the grid operators of Slovenija and Croatia started a joint project SINCRO.GRID. Within the scope of the project they built a static synchronous compensator or STATCOM in the substation Beričevo. In this thesis the composition and operation of the STATCOM is described, as well as the course of the project, from the planning phase to building and commissioning.
While undergoing traineeship at Kolektor Igin d. o. o., I had the opportunity of visiting the newly built STATCOM. The company also supplied me with information and project documentation which is the basis of this thesis.
