AbstractThis paper presents a comparative study for five artificial intelligent
(AI) techniques to the dynamic economic dispatch problem: differential
evolution, particle swarm optimization, evolutionary programming, genetic
algorithm, and simulated annealing. Here, the optimal hourly generation schedule
is determined. Dynamic economic dispatch determines the optimal scheduling of

AbstractThis paper presents an improved load flow technique for a modern
distribution system. The proposed load flow technique is derived from the
concept of the conventional backward/forward sweep technique. The proposed
technique uses linear equations based on Kirchhoff’s laws without involving
matrix multiplication. The method can accommodate changes in network structure
reconfiguration by invo... hiện toàn bộ
AbstractThe problem of optimal reactive power dispatch (ORPD) is one of the most
popular and widely discussed problem in power system engineering all over the
world. Optimal reactive power dispatch is one of the sub-problems of the optimal
power flow which is complex and nonlinear problem, which can be formulated as
both single- and multi-objective. In this paper, the problem has been formulated

AbstractSince it is one of the world's most significant financial markets, the
foreign exchange (Forex) market has attracted a large number of investors.
Accurately anticipating the forex trend has remained a popular but difficult
issue to aid Forex traders' trading decisions. It is always a question of how
precise a Forex prediction can be because of the market's tremendous complexity.

AbstractAs the world strives toward meeting the Paris agreement target of zero
carbon emission by 2050, more renewable energy generators are now being
integrated into the grid, this in turn is responsible for frequency instability
challenges experienced in the new grid. The challenges associated with the
modern power grid are identified in this research. In addition, a review on
virtual inertial c... hiện toàn bộ
AbstractThis article presents the characterization of analog and digital control
loops using PID/PIDN control algorithms for bidirectional buck–boost converter
(BBC). Control loops of BBC are designed and implemented in MATLAB code using
transfer functions in time domain with unit step response and in frequency
domain with bode plots and pole-zero plots. These transfer functions are
obtained by av... hiện toàn bộ
