In this paper, an energy management strategy in a Hybrid Electric Vehicle (HEV) is studied. This HEV is powered by a Fuel Cell (FC), and a Li-Ion battery. The FC supplies average power during the steady state and the battery furnishes the peaks of power during transient responses due to its high power density compared to the FC. This energy management, based on a fuzzy logic approach, aims to increase...
This paper present an optimal photovoltaic-hydrogen standalone power system using gray wolf optimizer technique. The system composed of photovoltaic generator and a hydrogen production system. Electrical power from solar conversion meets the user loads and the surplus used for water electrolysis to produce hydrogen. Control system is ensured via feed bucks control loops. MPP Tracking regulates with...
This paper deals with the development of intelligent power control and energy management of a photovoltaic-hydrogen hybrid system used in standalone application. Electrical power from solar conversion meets the user loads and the surplus used for water electrolysis to produce hydrogen. The system controlled by using an intelligent power conditioning units based on echo state network to ensure good...
The satellite in geostationary orbit present many flexibility due to flexible appendages, solar pressure and fuel sloshing in the tanks which they pose great challenges for accurate attitude control. In this paper, an anti-disturbance proportional-derivative (PD) controller is designed to stabilize the attitude while rejecting the effects of flexible vibrations, environmental disturbances, and unmodeled...
This paper exposes a novel optimization technique named Water Cycle Algorithm (WCA) for solving Economic Dispatch (ED) problem considering practical generator constraints as Prohibited Operating Zones (POZ) and Ramp Rate Limits (RRL) for smooth and non-smooth fuel cost curve of objective function without and with valve point effect, respectively. The proposed technique is applied on three test systems...
