In today's world, as electrical energy becomes increasingly essential, electrical power systems are also evolving. To make their development more efficient, renewable energy sources are increasingly being used. This paper focuses on one of the most cost-effective renewable energy sources, which is wind energy. It is used because it is "free," does not pollute the environment, and has no harmful waste associated with it. A wind farm consists of multiple wind turbines, and in them, the kinetic energy of the wind is converted into mechanical energy and then into electrical energy. Some wind turbines have the ability to regulate voltage conditions, while others do not, but those that can regulate voltage are more commonly used. The voltage regulation process itself relates to the transmission network, and the network used here is taken from reference [1] as it continues from that work. This paper briefly explains the purpose of a wind farm. The emphasis of the paper is on voltage regulation methods, where some examples of classical regulation are first explained, followed by more modern approaches. Next, wind farms (WFs) are explained in more detail, their role in voltage regulation, methods of implementing wind turbines, and two examples of WFs are presented, depending on their location - onshore and offshore. Afterward, a model of the WF network [1] is presented, on which various simulation examples have been performed, explained, and depicted in block diagrams. Specifically, using the example of a WF with a total of 23 wind turbines, voltage regulation was performed using a remote busbar, where the WF initially regulated voltages at the WF busbars and then the remote busbar in Gračac. The aim of the simulations was to find an optimal solution to increase the voltage at the Gračac busbar by regulating it with the voltage of the WF. In the end, the examples are described, explained, and various graphs are shown. The results of all examples are compared, followed by a conclusion.
