Implementation of multi input DC-DC converter based fuel minimisation in hybrid vehicle using HBO optimisation method

This manuscript proposes a multi input DC to DC converter based on fuel minimisation in hybrid vehicle using heap based optimisation (HBO) method. The proposed system inputs include fuel cell (FC), energy storage system (ESS), and photovoltaic (PV) group. Fuel cell is regarded as important MN power source and the roof-top photovoltaic is utilised for charging batteries, improving performance and reducing fuel economy. The converter has the ability to provide power demand from one or two resources that are not present through a load. Moreover, a power management method is defined and given in the heap-based optimiser (HBO) technique. The main objective of the proposed method is to "meet tight direct current (DC) bus voltage regulation, better monitor the PV current to their reference and minimise fuel consumption". The proposed HBO technique based hybrid electric vehicle (HEV) system is implemented in MATLAB/Simulink software.
