Larger penetration of distributed generation and active loads is expected in the near fu- ture. These new loads have brought up new challenges to the electrical networks as well as new possible opportunities. The possibility of using these new elements to regulate and control the voltage is considered as the future scenario. Therefore this thesis, develops a coordination between the most common elements in the networks (capacitor banks, STATCOMs, OLTCs/VRs and DGs), in order to study their interaction and how they together could manage the voltage level. In addition, EV charging station integration has been also evaluated. Considering this scenario, several simulations varying different parameters such as time delay or bandwidth are carried out. Also the concept line compensation is taken into consideration in the networks analysed. Through all the simulations accomplished it is proved that a coordination is necessary between all the elements. Later on, a discussion about how each configuration affects the network complete this thesis. Besides, the simulated scenarios show that DGs and EVs can contribute to voltage regulation in an efficient way.
