One of the most important operational requirements for any electrical power network for both distribution and transmission level is voltage control. Many studies have been carried out to improve or develop new voltage control techniques to facilitate safe connection of distributed generation. In Saudi Arabia, due to environmental, economical and development perspectives a wide integration of photovoltaic (PV) generation in distribution network is expected in the near future. This development in the network may cause voltage regulation problems due to the interface with the existing conventional control system. Therefore, a new control system with PVs should be developed. This paper introduces a new voltage control scheme for residential area networks in Saudi Arabia based on Fuzzy Logic concept (FL). The structure of two implementations of FL controller to regulate the voltage by setting the on-load tap changing transformer is proposed. In order to confirm the validity of the proposed methods, simulations are carried out for a realistic distribution network with real data for load and solar radiation. Results showing the performance of each implementation are presented and discussed.
