Abstract
Reactive power co
ntrol is the most efficient and popular voltage control method, especially for variable active power
demand. Static Var Compensators (SVCs) are being increasingly employed in modern power systems. This paper proposes
an Artificial Neural Network (ANN) base d Static Var Compensator (SVC) controller and a novel bus reducing methud.for
power systems. Two types of artificial neural network controllers namely are Multi Layer Perceptrons (MLP) with back
propagation learning algorithm, and Radial Basis Function (RB F) network are used. In the simulations, a variable power
demand is modelled as a disturbance effect and voltage stability control was done at the operating points with SVC. It is
shown that the voltage output was successfully regulated and desired voltage value are obtained quickly. Transient
responses for voltage and susceptance show that SVC controller with ANNs provide optimum system performance for a
disturbance effect. Performance of ANN based SVC controllers were tested. The effectiveness and feasibi lity of the
proposed control is demonstrated with the simple two bus system and three machine nine bus WSCC system. The results
show that improvement especially ANN based RBF controller has better performance the MLP based controller..
