Research on the capacity cost allocation and the electricity capacity price optimization method for a power system based on the BARY‐GA algorithm

Energy Science &Engineering, Volume 12, Issue 1, Page 168-180, January 2024.
Description: This work studied and proposed a mechanism for the formation of capacity and electricity prices based on the proportion of allowed income and fixed costs at different voltage levels. The genetic algorithm (GA) has been proposed to calculate the electricity capacity price and electricity quantity's electricity price at all levels of load ...

TOFD IMAGING SYSTEM IN NONDESTRUCTIVE TESTS

, 2012
This paper shows how the symbiosis of two disciplines, software engineering and ultrasonic techniques, made possible the development of a nondestructive testing system for TOFD imaging, and it also allowed to make the application of commercial computation tools independent.
