Risk Analysis for Adaptive Centralized Protection Scheme for Electric Distribution Systems in Presence of Distributed Generation
نویسندگان
چکیده
Electric distribution networks have a simple protection system including fuses, re-closers, and overcurrent relays. One of the negative effects of DG installation in distribution network is miscoordination of protection devices and conflict between DG operation as islanding mode and protection purposes. This paper for overcoming to this difficulty proposes an efficient algorithm based on dividing a distribution network into several zones, each zone, capable of operating in island operation. In the proposed method, risk analysis is used to optimize the protection zones by optimal placement of protective devices. The proposed scheme has been implemented on a real distribution network.

The change in the topology of active distribution networks (ADNs) is one of the essential challenges that might affect the protection schemes. The conventional protection schemes based on base topology result in some coordination constraint violations in other topologies due to the outage of upstream substations and distributed generation units. In this article, new combinational and adaptive p...

متن کاملAn Improved Under-Frequency Load Shedding Scheme in Distribution Networks with Distributed Generation
When a distribution network consisting of Distributed Generations (DGs) is disconnected from upstream network, the system may be exposed to severe power imbalance. In order to prevent the damage of power plants, frequency relays operate and remove DGs from the network. In contrast to traditional methods, the main objective in new methods is to keep DG units in service in the islanded distributi...
