Battery powered electric vehicle technologies are advancing in the present world for minimizing the global warming effects. The electric vehicle concept comes as alternate to internal combustion engine vehicles that uses electric energy from electric energy storage systems of high-energy capacity and long-life cycle. Lithium-ion (Li-Ion) batteries are utilized as energy storage in most of the electric...
Due to the increasing awareness of oil depletion and the growing appreciation for green technology, electric vehicles (EVs) are now a widespread form of vehicle transportation. Single-source EVs such as battery electric vehicles (BEVs) have the drawbacks of limited life cycles and self-discharge. This paper proposes a test bench model to evaluate the performance of a multi-source light electric vehicle...
This paper introduces a new proposed design and optimization simulation program for techno-economic sizing of stand-alone hybrid PV/wind/diesel/battery energy system. The main function of the new proposed simulation program (NPSP) is to determine the optimum size of each component of the hybrid energy system (HES) for lowest cost of kWh generated at highest reliability. An accurate methodology for...
This paper presents modeling, simulation and performance evaluation of grid integrated photovoltaic (PV) with battery energy storage system (BESS). The battery energy storage provides additional benefit for DC bus voltage regulation, where it is interfaced to the common DC bus of the PV power conversion system. A control method for state of charge and BESS charge/discharge is proposed to ensure an...
This paper presents a new energy management system (EMS) for small hybrid electric vehicle (HEV), which utilizes energy from the combination of battery, fuel cell (FC) and super capacitors (SC). These alternative energy sources are excellent potential solution to the ever-rising price of petrol. The major focus of this paper is the energy management system, which consists of a strategy to coordinate...
In this research an iterative method for determining the optimal sizing of standalone photovoltaic (PV) system in terms of optimal sizing of PV array and battery storage is proposed. A standalone PV system energy flow is first analysed using a developed model for a standalone PV system. In finding the optimal size of PV array and battery, a long term data (1975–2005) is considered for Malaysia. Based...
microgrid systems is a new technology for improving reliability and providing alternative energy supplies to the grid system. Low voltage faults in the system are one of the critical issues that require distributed generating sources to disconnect from grid provide energy to the load. Therefore the techniques used in the micro grid system with micro soures can be important in reducing the problems...
