Load Shedding in Deregulation Environment and Impact of Photovoltaic System with SMES

The effects of bilateral contracts on the dynamics of a system including three areas, each of which consisting of two GENCOS and two Discos has been discussed. A case study of contract violation of DISCO's also being incorporated. For all the three strategies the critical load at which frequency of the areas tries to go below minimum allowable range also has been calculated. With the help of MATLAB software using Simulink, results have been obtained. From the comparison results indicates that on using the third strategy (with additional sources) we are increasing the efficiency of the system. When using system with PID controller and additional sources, frequency of the system doesn't go below minimum allowable range and there is requirement of load shedding has been eliminated.
