This paper presents a dynamic load distribution scheme including a static synchronous compensator (STATCOM) with a proposed nonlinear controller, applied to a studied radial distribution network. Using this model, all the nonlinear equations governing the distribution network have been extracted, and the proposed dynamic power distribution, based on the phasor method, is used to investigate the network dynamics. In the simulation, it is assumed that each motor starts when the other has reached steady state. To provide the reactive power required by the motors, a static synchronous compensator is used, which is controlled by a combination of two controllers: a Passivity-Based Controller (PBC) and a lag phase compensator (LPC). So it could maintain the bus voltage at the reference value and prevent voltage drop, particularly during motor starting intervals. The simulation results, carried out in MATLAB, show that the proposed static synchronous compensator controller effectively improves the dynamic stability of the studied radial distribution network.
