POWER-FLOW CONTROL BY USE OF CONTROLLABLE SERIES COMPONENTS

This paper deals with power flow control in electric power systems by use of controllable series capacitors and phase shifters. Models suita ble for incorporation in power flow programs are developed and analyse d. The power flow control problem is defined in a stringent way and a method for solving the power flow control problem is proposed based on decomposition. This method is applied on test systems and the converg ence rate of the algorithm is discussed. Simplified models of the comp onents are also derived. These simplified models are shown to be quite accurate in most situations, and are used to construct regions of fea sible power flows of the controlled lines.
