Abstract :
The expected insertion of DG (distributed generation) in the distribution networks entailed by environmental, regulation and economical aspects will modify the way the entire system is planned and operated. Due to its dispersed nature, DG will require more flexible operated system. This situation will emerge through various applications and developments of the distribution automation. In addition, DG has already showed some impacts on system security. Thus a special attention should be paid to the DG influence during emergency states such as the propagation of cascading failures or other major events. Indeed, in one hand, a high amount of DG can improve the system response to these disturbances but, on other hand, a massive DG insertion could endanger the system operation. The presentation will cover the criticality of power system, particularly distribution networks, with regards to DG insertion. New ICT functions needed for improvement of DG insertion and performance will be discussed.
