Along with number of benefits, wide-scale penetration of distributed generation (DG) units in distribution system imposes some critical challenges for power engineers. The major issues with interconnection of small DG units are related to protection, voltage control and power quality. Furthermore, overall system stability can also be affected due to the lack of fault ride through (FRT) capability...
Along with a number of benefits, large penetration of distributed generation (DG) units in the distribution system imposes some serious challenges for power engineers. Slow voltage recovery under post-fault condition turns up as one of the most critical problems in small DG integration. Majority of the small DG units trip due to lack of fault ride-through (FRT) capability, and hence, challenges the...
This paper proposes a simple methodology for placing two principal types of DG units - synchronous machine and induction machine with an objective of enhancing loadability of distribution system. The proposed methodology is based on the concept of reactive power margin. Buses have been ranked based on the reactive power margin and grouped as “strong” and “weak” buses for finding suitable location...
