In this paper, a transient study on Isolated Wind-Diesel Hybrid System (IWDHS) of 200 kW has been carried out in MATLAB/SIMULINK environment. The detailed model of synchronous generator coupled to diesel engine, self-excited induction generator and load is studied and considered for analyzing the dynamic behavior of IWDHS. It has been taken into consideration that most of the time; the energy is to be provided by wind turbine in comparison to diesel generator. Instead of a fixed wind speed, the IWDHS is being supplied by variable wind speeds. that are more than its nominal value (10 m/s). This function is accomplished by using a conventional PI controller which regulates the pitch angle of the wind turbine blades during incoming varying gusts of wind. Further the system performance is improved by implementing an ANFIS controller. A controller design process is identified; it consists of generating input-output data pairs to identify the control variables range and initial fuzzy memberships, and then to tune or adapt them using an ANFIS network structure. The control objective was to extract maximum power at varying wind speeds and to limit the power as well as improve settling time at rated value at high wind speeds. The simulations have shown how advantageous an ANFIS based controller is over a conventional PI controller.

“…Methods to improve SEIG operation can be split into two categories: i) regulation by means of a variable Volt-Ampere Reactive (V AR) source [5][6][7][8][9] and ii) regulation using an ELC to adjust power in a resistive dwnp load [2][3][10][11][12][13]. Variable V AR approaches are complicated; they require costly control circuitry and they need skilled installation and skilled maintenance persons.…”

Constant voltage and frequency can be generated by a stand-alone Self-Excited Induction Generator (SEIG) driven with a fixed-speed low-head hydro-turbine when the electrical load is maintained constant by an Electronic Load Controller (ELC). However for a Conventional-ELC (C-ELC) most of the generated electrical energy can be dissipated in the dump load if the village load is low. So, the objective of this research is designing a simplified ELC for each household to transfer the excess power for domestic consumption in addition to providing voltage regulation for the generator. A regular ELC, possibly of reduced rated power, should still be installed at the generator site. At the same time, a simplified and inexpensive ELC is installed at each household. The proposed controller, installed in each household, is referred to as the Distributed Electronic Load Controller (DELC). MATLAB simulation results verify the feasibility of the proposed approach. Experimental results using the MSP-430 LaunchPad microcontroller are also presented to verify the validity of the proposed DELC approach. Keywords-ELC, dump load, Distributed ELC (D-ELC), bi directional power switch, Pulse Width Modulation (PWM) I.

Self-excited induction generators (SEIGs) will play an important role in off-grid wind power generation. To advance understanding of the significance and prospects of SEIGs, this paper elucidates the significance of incorporating the proximity effect in the conventional model of self-excited induction generators. The researchers offer an analytical model to incorporate the proximity effect in the rectangular rotor bars of the SEIG. The model's accuracy relies on a computer program. The calculated results are experimentally verified in the case of two 7.5 hp aluminium-and copper-rotor SEIGs under open-circuit and static loading conditions, through an exclusive qualitative analysis of terminal voltage build-up at no-load, variation in terminal voltage and frequency, as a function of the proximity effect. The paper examines also the voltage regulation, frequency regulation and excitation capacitance requirements of both aluminium-and copper-rotor SEIGs.
