In the future, with the high penetration level of the distributed generation, their decoupling from network during the fault will eventually cause critical consequences. In order to avoid such situation, it is necessary to perform the transient stability analysis. The paper investigates the hybrid methods for fast transient stability assessment which are able to detect quickly the loss of stability...
The major change in the last decade concerning distribution network is related to the penetration of distributed generation (DG). The current practice in France concerning the connection of DG was to fit the network to the worse case of use of DG to avoid any problem. This approach will reach his limits and many developments will be necessary to optimize the network operation, taking the presence...
This paper presents a case study based on a real distribution network with a high share of distributed generation. We built the simulation on the present network topology and generated a scenario for the expected future with a high penetration of DER (distributed energy resources) and an increase of the consumption. Even with a load growth exceeding the substations capacity the simulated network can...
As the penetration level of the distributed generations on distribution network will increase, they must take their share of responsibility in the system security and provide flexibility and controllability necessary to support secure system operation. However, following the occurrence of large disturbances on the network (short-circuits, line outage, voltage dips...) the protective disconnection...
A high penetration of distributed generation (DG) may influence the operation and control of the distribution system and the transmission system, leading to technical issues that must be identified and analyzed. The distributed generators are small or medium scale units connected to the low or medium voltage networks (LV or MV). Due to their low inertia for small rotating machines, these distributed...
