Optimal Combined and Adaptive Protection of Active Distribution Networks Considering Different System Topologies Incorporating Optimal Selection of Standard Relay Curves
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 کاملAdaptive Protection Based on Intelligent Distribution Networks with the Help of Network Factorization in the Presence of Distributed Generation Resources
Factorizing a system is one of the best ways to make a system intelligent. Factorizing the protection system, providing the right connecting agents, and transmitting the information faster and more reliably can improve the performance of a protection system and maintain system reliability against distributed generation resources. This study presents a new method for coordinating network protect...
متن کاملAdaptive Relay Protection Concept for Smart Grids
Smart Grid refers to an intelligent grid that employs modern information and telecommunication technologies to meet the challenges relating to the power delivery in the future. These challenges are due to, among others, increased use of renewable energy and power supply reliability requirements of modern digital society. In order to fully realise the Smart Grids a new kind of approach for the p...
متن کاملRelay Feedback and Multivariable Control
This doctoral thesis treats three issues in control engineering related to relay feedback and multivariable control systems. Linear systems with relay feedback is the first topic. Such systems are shown to exhibit several interesting behaviors. It is proved that there exist multiple fast relay switches if and only if the sign of the first non-vanishing Markov parameter of the linear system is p...
متن کاملAdaptive 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...
