Adaptive Protection Algorithm for Overcurrent Relay in Distribution System with DG

Adaptive Protection Algorithm for Overcurrent Relay in Distribution System with DG

This paper proposes the new adaptive protection algorithm for inverse-time overcurrent relays (OCRs) to ensure their proper operating time and protective coordination. The application of the proposed algorithm requires digital protection relays with microcontroller and memory. The operating parameters of digital OCRs are adjusted based on the available data whenever system conditions (system wi...

Multi-agent based protection system for distribution system with DG

This paper introduces the basic structure of multi-agent based protection system for distribution system with DGs. The entire system consists of intelligent agents and communication system. Intelligent agents can be divided into three layers, the bottom layer, the middle layer and the upper layer. The design of the agent in different layer is analyzed in detail. Communication system is the brid...

Application of Fuzzy and ABC Algorithm for DG Placement for Minimum Loss in Radial Distribution System

Distributed Generation (DG) is a promising solution to many power system problems such as voltage regulation, power loss, etc. This paper presents a new methodology using Fuzzy and Artificial Bee Colony algorithm(ABC) for the placement of Distributed Generators(DG) in the radial distribution systems to reduce the real power losses and to improve the voltage profile. A two-stage methodology is u...
