Nonlinear evolution of the electroconvective flow patterns is analysed in a horizontal low conductive fluid layer under heating from above and under modulated charge injection. To examine the complex evolution of the system, numerical simulations are carried out using a finite difference method. The influence of amplitude and frequency modulation on the oscillatory electroconvection is studied. Traveling waves with modulated amplitudes and phase velocities and synchronously modulated patterns are found as stable solutions.
