Abstract

Control voltage in power system is always necessary to guarantee power quality and reduce power loss of productivity. This paper presents the construction of voltage control fuzzy system in transmission network with variety control devices, used fuzzy Mamdani controllers. Fuzzy controllers associated and combined control actives to create an unified fuzzy control systems capable of automatically controlling the voltage at the nodes in power system by retaining nodes voltage in a while desired values with the satisfying restrictive conditions. Through the investigative results on 30bus IEEE standard network demonstrated the effectiveness of the proposed fuzzy algorithm compared with conventional techniques sensitive tree.
