The dynamic performances of a hybrid wind turbine generator system using a shaft generator system are investigated. The hybrid system consists of a wind turbine and generator, a rectifier, a current-source thyristor inverter, a synchronous generator driven by a prime mover and a duplex reactor. The configuration of the hybrid wind turbine generator system is explained first, and a dynamic model of...
With the increasing concerns on air pollution and global warming, the clean green renewable sources of energy are expected to be playing more significant role in the global energy future. Multi-source hybrid power generation systems are representative applications of the renewables' technology. In this investigation, wind turbine generators, photovoltaic panels, and storage batteries are used to build...
The paper presents a simulation for energy short term storage unit integrated into a stand alone hybrid wind diesel system. The energy short term storage unit is a flywheel device which is driven by a 6/4 switched reluctance machine (SRM) operating in motor and generator modes. The control strategy is developed to smooth the wind power turbulence fluctuations in order to decrease the fuel consumption...
This paper proposes a hybrid energy system combing solar photovoltaic and wind turbine as a small-scale alternative source of electrical energy where conventional generation is not practical. A simple and cost effective control technique has been proposed for maximum power point tracking from the photovoltaic array and wind turbine under varying climatic conditions without measuring the irradiance...
This paper deals with power control of a wind and solar hybrid generation system for interconnection operation with electric distribution system. The proposed system consists of a variable-speed direct-drive wind generator, wind-side converter, solar array, dc-dc converter and grid interface inverter. Power control strategy is to extract the maximum energy available from varying condition of wind...
This work presents a modeling and control design for a wind-hybrid power system with a battery storage. The proposed control scheme is based on the Takagi-Sugeno fuzzy model and the linear quadratic regulator. The Takagi-Sugeno fuzzy model expresses the local dynamics of a nonlinear system through subsystems partitioned by linguistic rules. The controllers for each subsystem are designed by the linear...
An energy management system based on hierarchical fuzzy controller for the distributed hybrid wind-solar power system is designed. Based on hierarchical fuzzy control, the energy management system switches the mode of power supply and controls the load share according to the condition of wind power, solar radiation and load requirement. Through the suitable allotter of the generation ratio from wind...
The Hybrid Wind/Closed Cycle Vapor Turbogenerator (CCVT) power system was developed to provide the most reliable, cost-effective remote power system available for loads in the range of 300 to 3000 watts. While the CCVT has a proven record of reliability, it requires fuel for its operation. On the other hand, the wind generator does not require any fuel but is subject to the vagaries of the wind. By...
In 1978, Bristol Aerospace presented a Paper detailing the work which was in progress on the industrial wind power program as sponsored by the National Research Council in Canada. This follow-up Paper will report on the preliminary operational results of systems undergoing In-Situ Familiarization Tests. The program has involved the following firms: Alberta Government Telephones, Saskatchewan Telecommunications,...
