This paper describes the modeling of integrated hybrid renewable energy system. The wind and solar are used as input sources for the hybrid system. The proposed system involves the design of photovoltaic (PV) and wind energy conversion system (WECS).The system is designed for constant wind speed and varying solar irradiation and insolation. Maximum power point tracking (MPPT) algorithm is used to extract the maximum power from PV array. The integration of two input sources is done by current-sourceinterface multiple-input (MI) cuk converter. Fuzzy logic controller is used to control the duty cycle of one of the converter switch thereby extracting the maximum power from solar array. The system consists of photovoltaic (PV) array, wind energy conversion system (WECS), multiple input current-source-interface cuk converter, voltage source inverter (VSI), LC filter and three phase load. The entire proposed system has been modeled and simulated using MATLAB/simulink software. The simulation results show that the proposed system generates a power of 30KW at low cost.

“…DG systems based on a single intermittent source, either photovoltaic (PV) or wind energy system are unreliable due to seasonal variations. DG systems consisting of two or more renewable sources have a higher reliability, due to the complementary nature of the resources [4,5]. In such hybrid schemes, permanent magnet synchronous generators (PMSG) are generally employed, as they do not require any reactive power support.…”

Abstract:A fuzzy inference system (FIS) based sensor less maximum power point tracking (MPPT) algorithm has been proposed. The Fuzzy based controller has the ability to track the maximum power point (MPP) and the corresponding rotor speed of the wind generator by estimating wind speed with very little error compared to the conventional MPPT techniques. The algorithm developed is based on two series fuzzy networks, one for wind speed estimation and the other to determine the maximum power point and the corresponding rotor speed. The method demonstrates remarkable performance in estimating wind speed and to predict MPP accurately without undesired oscillations around maximum power point. The algorithm does not require any mechanical sensor for wind speed measurement. Nonlinear time domain simulations have been carried out to validate the effectiveness of the proposed controllers under different operating conditions. Simulation results confirm the effectiveness of the proposed MPPT controller in tracking the maximum power point under rapidly changing wind conditions.

“…At high wind speed, the electrical frequency increases and the reactive impedance of the generator will be high, while the impedance of the battery load will be low. In this case, the poor impedance matching will limit power transfer to the DC system (Yamamura et al, 1999;Borage, 2005;Daniel and Gounden, 2004;Arutchelvi and Daniel, 2006;2007).…”

“…Control of the DC-DC converter may be achieved by means of maximum power point tracking (Daniel and Gounden, 2004) or by means of a pre-determined relationship between wind speed and rectifier DC voltage (Arutchelvi and Daniel, 2006;2007). Maximum power point tracking requires continuous variation of the DC voltage to determine whether the output power may be increased.…”

The aim of this study is to simulate and implement open loop and closed loop controlled DC-DC converter for stand-alone wind energy system. Wind turbines, however, are not always very efficient in the wind speeds that are most common to a region. Typically, wind energy systems are designed to be highly efficient in high wind speed and have a cut-off wind speed-below which no energy is captured. In remote locations where wind energy is used for battery charging, the energy lost below the cut-off wind speed could be used for trickle charging or maintaining a battery's fully charged state. Wind turbines are most efficient when they are operated at one specific Tip-Speed to Wind-Speed Ratio (TSR). Therefore, for the efficient capture of wind power, turbine speed should be controlled to follow the ideal TSR, with an optimal operating point, which is different for every wind speed In this system, the DC-DC converter in the DC link with a constant dc voltage to the load, a DC-DC converter will allow the voltage at the output of a diode bridge rectifier to be controlled. In low wind speed conditions, the voltage may be lowered to prevent the dc link from reverse biasing the diode rectifier. Under high wind speed condition, the voltage may be increased, reducing I2R losses. In addition, adjusting the voltage on the dc rectifier will change the generator terminal voltage and thereby provide control over the current flowing out of the generator. The LCL-T resonant inverter system for both open loop and closed loop DC-to-DC converter systems are simulated using MATLAB simulink power system blocks. This converter has advantages like reduced transformer size, reduced filter size and current source characteristics. The simulation studies indicate that LCL-T type for open and closed loop DC-DC converter can be used with stand-alone wind generator. Constant voltage can be maintained at the output of DC-to-DC converter by using a PWM rectifier at the output. Embedded controlled DC to DC converter is fabricated and it is tested.
