Despite providing positive impacts on the quality of life, some devices suffer from various defects such as substantial environmental concerns and high-energy bills. As a relatively modern residential power tool, a home-connected Green Electric Vehicle (GEV) can discharge energy and supply power to the Home. This paper proposes a combined home Energy management system including Vehicle -To- Home (V2H) technology (or Home Centralized Photovoltaic-HCPV)). The proposed approach seeks to control home energy demand by scheduling optimal automation appliances. Without additional grid power, the proposed HCPV design will cover household electricity demand in sunny and cloudy weather. In contrast, the combination of PV and electricity transmitted by V2H is sufficient to meet household load demand by cloudy weather. In this vein, a scheduling Home Energy Management System is designed and discussed with various constraints to perform correct system operations and satisfy load demand. The proposed algorithm attempts to characterize and perceive source circumstances utilizing energy demand. The obtained results demonstrate that H2V operating technology is can effectively be reducing energy demand under solar-load volatility.

The PEMFC source may not be sufficient to satisfy the power required, especially, the peak demand periods. So, we use an Ultra-Capacitor (UCap) because it offers a very fast power response and a high specific power. In addition, the UCap can round off the slowdown of the main source output power to produce the effectiveness and performance characteristics needed to a variable load. A regulation for the PEMFC and the UCap was given. Furthermore, a Power Management Unit (PMU) is proposed in order to reach the good functioning of the system. The analysis and the evaluation of the PMU is performed through simulation results to verify the reliability and the effectiveness of the proposed system using Matlab/Simulink environment.

The PEMFC cannot sufficiently meet sustained load demands in some cases. For that, to compensate this problem incorporating the slow transient response of the PEMFC, Ultra-capacitors (UCaps) are potential candidates for a solution in this aspect. An adequate Energy management System (EMS) is one essential objective of the researches in this area. Hence, this paper proposed an efficient dynamic model using an energy storage system with the sufficient power capacity to keep the smooth operation of the system. To satisfy the load requirements and optimize the active power flow between hybrid power sources for different modes, the EMS was proposed. This latter was appreciated for its capacity to serve the required power through effective utilization of the PEMFC and UCap. To maximize the system efficiency, the functioning of the system is depending on the decision making and the control of all the system component states. The HES and the control approach are made using Matlab/Simulink environment, from which, the obtained results indicate the reliability and the effectiveness desirability of the HES and its proposed energy management strategy.

The PEMFC cannot sufficiently meet sustained load demands in some cases. For that, to compensate this problem incorporating the slow transient response of the PEMFC, Ultra-capacitors (UCaps) are potential candidates for a solution in this aspect. An adequate Energy management System (EMS) is one essential objective of the researches in this area. Hence, this paper proposed an efficient dynamic model using an energy storage system with the sufficient power capacity to keep the smooth operation of the system. To satisfy the load requirements and optimize the active power flow between hybrid power sources for different modes, the EMS was proposed. This latter was appreciated for its capacity to serve the required power through effective utilization of the PEMFC and UCap. To maximize the system efficiency, the functioning of the system is depending on the decision making and the control of all the system component states. The HES and the control approach are made using Matlab/Simulink environment, from which, the obtained results indicate the reliability and the effectiveness desirability of the HES and its proposed energy management strategy.

To achieve this goal, the system is composed of two energy sources one, as a renewable energy, serves to primary load feeding while the other, based on hydrogen conversion, works as a backup system. Thus, the system includes two kinds of energy storage devices one is used to chemical form energy storage (H 2 gas) while the second, based on ultracapacitor storage, is dedicated to electricity power saving. The functioning of system depends on a smart energy management that is based on the decision making and the control of all the system components states to achieve a high efficiency and better performance. Hence, the reliability and the effectiveness of the proposed system are tested by Matlab/Simulink environment, from which, the obtained results have been presented and discussed in details.

A Proton Exchange Membrane Fuel Cell (PEMFC) is considered as a mainly source that supplies a load. An energy flow management approach is detailed in order to satisfy the load requirements despite the absence of any other power source. Finally, an analysis of the simulation results is conducted using Matlab/Simulink software in order to verify the performance of the proposed system.

The developed model is represented in the state space, so it can be used to implement a suitable control strategy. The given design shows that the transient behavior, effect of the Fuel Cell, is eliminated by the use of the Ultra capacitor through the Flyback converter (FlBC). Thus, the output voltage from the source is maintained with a certain range and meets power demand of the load at high efficiency.
