Abstract

In this study, Dynamic Stability studies on smart grids is done locally in the micro grid. A model of the micro-grid includes photovoltaic sources and synchronous generators as well as Interface Converters and induction motors (dynamic load) and finally the governor. First the nonlinear model of micro grid equipment mathematic presented and then how arrangement connection equipment designed. After that state-space model through a linear operating point occurred and also the purpose of the research from the first Lyapanf method to obtain the values of matrix mode achieved its goal. Photovoltaic voltage source converter control is performed by controlling the sliding mode. To ensure the values of the setting MATLAB non Time, calculation conducted through Hifrun Philips taken to the environment and its validity proving was drawn for occurence to enhance the stability of the micro grid through increasing the damping torque oscillation modes, a controller is added to the system that will guarantee in the moments of upheaval.
