[more ▼] The amount of inverter based distributed generation (DG) connected to the low and medium voltage levels is increasing rapidly. Their growing impact on the power system has already driven some distribution network operators to start imposing requirements on their operation similar to those described in transmission grid codes. This paper studies how different grid code requirements can affect the fault current levels in the distribution network and explores the possibility of using the grid code requirements to ensure the reliability and selectivity of the protection of distribution feeders.

[more ▼] Conventional short circuit calculation programs do not consider the actual behavior of inverter based distributed generation (DG). Several techniques to consider them have been suggested in literature and are briefly described in this paper. A tool is developed with the combination of these techniques. The approach uses standard short circuit calculation tools and accommodates inverter based DG with different fault responses. The approach is evaluated and compared against other techniques using a realistic test distribution network model. [less ▲] Detailed reference viewed: 155 (6 UL) |
