The parameter identification of a PEMFC is the process using optimization algorithms to determine ideal unknown variables suitable for development an accurate fuel-cell-performance prediction model. These parameters are not always available from manufacturer’s datasheet, so they need be determined accurately model and predict fuel cell’s performance. Five methods—bald eagle search (BES) algorit...

Low-frequency oscillations are an inevitable phenomenon of a power system. This paper proposes Ant lion optimization approach to optimize the dual-input system stabilizer (PSS2B) parameters enhance transfer capability 400 kV line in North-West region Ethiopian electric network by damping low-frequency oscillation. Double-input Power stabilizers (PSSs) currently used systems damp out oscillation...

The Antlion Optimization (ALO) algorithm is a meta-heuristic optimization based on the hunting of ants by antlions. basic inadequacy this that it has long run time because random walk model used for ant's movement. We improved some mechanisms in ALO algorithm, such as ants' walking, reproduction, sliding towards antlion, elitism, and selection procedure. This proposed called Improved (IALO) alg...

An IoT healthcare system refers to the use of Internet Things (IoT) devices and technologies in industry. It involves integration various interconnected devices, sensors, systems collect, monitor, transmit health-related data for medical purposes. Blockchain-assisted intrusion detection on is an innovative approach enhancing security privacy sensitive data. By combining decentralized immutable ...

This paper studies the problem regarding optimal power dispatch of photovoltaic (PV) distributed generators (DGs) in Direct Current (DC) grid-connected and standalone networks. The mathematical model employed considers reduction operating costs, energy losses, CO2 emissions as objective functions, it integrates all technical constraints implied by DC grids a scenario variable PV generation dema...
