Adaptive Unit Protection for Lines Connecting Large Solar Plants Using Incremental Current Ratio

An adaptive modified firefly algorithm to unit commitment problem for large-scale power systems

Unit commitment (UC) problem tries to schedule output power of generation units to meet the system demand for the next several hours at minimum cost. UC adds a time dimension to the economic dispatch problem with the additional choice of turning generators to be on or off.  In this paper, in order to improve both the exploitation and exploration abilities of the firefly algorithm (FA), a new mo...

Distributed Incremental Least Mean-Square for Parameter Estimation using Heterogeneous Adaptive Networks in Unreliable Measurements

Adaptive networks include a set of nodes with adaptation and learning abilities for modeling various types of self-organized and complex activities encountered in the real world. This paper presents the effect of heterogeneously distributed incremental LMS algorithm with ideal links on the quality of unknown parameter estimation. In heterogeneous adaptive networks, a fraction of the nodes, defi...

A New Approach to Current Differential Protection for Transmission LInes

Current Directional Protection of Series Compensated Line Using Intelligent Classifier

Current inversion condition leads to incorrect operation of current based directional relay in power system with series compensated device. Application of the intelligent system for fault direction classification has been suggested in this paper. A new current directional protection scheme based on intelligent classifier is proposed for the series compensated line. The proposed classifier uses ...

Incremental Rules for Growing Plants

L-systems are widely used for plant modeling and simulation, with remarkable results. However, we argue that the mathematical formalism underpinning L-systems encourages inefficient rendering of plants which grow and change over time. We propose new types of rules which emphasize the incremental nature of change in a plant’s elements, and highlight an element’s relationships with other componen...
