Small wind turbines (in the range 2–50kW) harvest wind energy to provide carbon free energy for residential and small commercial applications and remote or developing economies. Current state-of-the art technologies generally utilize simple diode bridge rectification of the output from brushless permanent magnet (PM) generators and grid connection via DC-DC converters and voltage source inverters...
Many theoretical control strategies have been proposed for hybrid electric vehicles (HEVs) during the past decade. Some of these theoretical control strategies are not suitable for real-time applications mainly because of their sensitivity to vehicle parameter variations and different driving habits of the drivers. The computation times of such algorithms are also long because of their high accuracy...
Generally, telecom power systems are connected to grid and diesel generator with batteries providing short/long term back-up power. This paper represents a new telecom power system using local micro-sources, i.e., a wind turbine driven brushless dc (BLDC) generator and a battery pack. Some benefits of this system are effectively eliminating the diesel generator, grid connection, and automatic transfer...
The design and analyses of a grid-connected residential photovoltaic (PV) system containing a plug-in hybrid electric vehicle (PHEV) load is presented in this paper. In this system, PV arrays and battery packs are cascaded to supply power to the load. Solar energy is harvested by PV arrays, the terminal voltage of PV arrays is regulated by a DC/DC converter to track maximum power point (MPPT) using...
Hybrid electric vehicles are proposed to reduce the fuel consumption and emission while sustaining performance of the vehicle. The key point to use the full potential of hybridization is designing a proper supervisory control strategy, which manages how to split the demanded power between energy sources in the most efficient and optimum way. This paper compares and classifies control strategies according...
The main objective of this paper is to design and analyze a residential photovoltaic system for plug-in hybrid electric vehicle load, in addition to regular residential requirements. This system is a combination of two subsystems which are cascaded through a DC link. First subsystem is the solar energy harvesting part with PV array, current controlled boost converter and maximum power point tracking...
A novel maximum power point tracking (MPPT) algorithm and a basic controller are introduced for a variable-speed direct-drive wind power plant. The control method is designed to keep system stable under all operating conditions and to track the maximum power flow to the utility with minimum time delay by steepest decent algorithm. Simulation results of the proposed control system shows good power...
