“…Experience using renewable energy sources, especially wind since 1970, and energy crises has contributed further to growing interest [1]. Wind energy is becoming quite popular compared to other renewable energy sources such as solar, biomass, tidal and wave [2]. Approximately, 10 million MW of wind energy is continuously available on the Earth [3].…”

The results of an investigation of the potential of wind energy as a power source are reported for an Iranian north-western city, Ardabil. The Weibull probability distribution function using a long-term data source, consisting of 6 years (2005-2010) of 3-h period measured mean wind data, is adopted and analyzed. The data have been measured at a height of 10 m above the ground level. Also, monthly and annual wind speed variations are analyzed. The monthly mean wind speed is between 2.09 and 6.58 m/s, while the annual mean wind speed is in the range of 3.28-4.08 m/s. The Ardabil site is found to have good characteristics from the perspective of mean wind speed. The numerical values of the shape and scale parameters for Ardabil are seen to vary over a wide range. The monthly mean value of shape parameter (k) is between 2.62 and 3.17, while the monthly mean value of the Weibull scale parameter (c) is between 3.36 and 5.43 m/s. The results show that the months of October and September have higher mean power densities and that July has a lower mean power density than other months. Also, the wind potential of the studied region is determined to be very suitable for the off-grid connections and could be acceptable for connecting to power grids.

“…Therefore, using power harvesting technologies may increase the lifespan of operation batteries. Green energy sources are available in different forms, such as solar power [12], wind energy [13], thermal energy [14], electromagnetic energy [15], and kinetic energy [16]. However, electromagnetic energy is unbounded and comes from different sources in which it is harvested without limitations.…”

Abstract-Due to urgent needs for exploring new energy resources, a novel approach is developed in this paper to integrate the functions of a photovoltaic (PV) panel with an ultra-wide band (UWB) antenna array as a unit for collecting solar energy and RF radiation power. The UWB antenna is printed on the front panel of the PV surface. The antenna structure is customized with minimum shadowing effects on the PV surface, by using eight monopoles connected to one SMA port as a single antenna array. Then, to ensure the bandwidth enhancement, each monopole is coupled to three Split Ring Resonators (SRR) structured in a single column as a matching circuit. Next, an experimental study is performed to investigate the amount of the harvested energy from both the PV and the antenna array. The antenna experimental measurements are conducted to realize the I-V characteristics for the PV and produced output voltage and efficiency from the RF radiation power at 900 MHz only. Numerically, the proposed antenna array performance is simulated by CST MWS and HFSS software packages. Finally, the antenna performance in terms of S 11 and the radiation pattern at 900 MHz are measured and compared to the simulated results to end up with excellent agreements.

“…The renewable source are being utilized to meet the ever increasing energy demand [1].Due to relatively low cost of electricity production [2]wind energy consider to be one of potential source of clean energy for the future [3]. A hybrid wind-battery system is considered to meet the load demand of a stand-alone Base Telecom Station (BTS).The advantage of battery energy storage for an isolated WECS is discussed in [4].With battery energy storage it is possible to capture maximum power [5] from the available wind.…”

Abstract:The main demand for renewable energy resources is increase in the price and limited availability of conventional energy resources. Available alternative sources of wind energy are neat and clean but due to the intermittent nature it can need back up. In order to ascertain continuous supply of potency felicitous storage technology is utilized as backup. In this paper, the sustainability of a 4-kW hybrid of wind and battery system is investigated for meeting the requisites of a 3-kW stand-alone dc load representing a base telecom station. A charge controller of battery bank charging and discharging depends on Fuzzy logic controller predicated maximum power point tracking and battery state of charge. The mechanical safety and electrical safety of wind energy conversion system is achieved by using pitch control technique. Both the control schemes are integrated and the efficacy is validated by testing it with various load and wind profiles in MATLAB/SIMULINK. [7]. In order to extract maximum power form WECS the turbine needs to be operated at optimal angular speed [7]. The BTS load requirement is modeled as a dc load which requires a nominal regulated voltage of 50 V. The WECS is interfaced with the standalone dc load by means of rectification ac-dc and buck converter dc-dc to regulate the load voltage at the desired level. The proposed control scheme utilizes the turbine maximum power tracking technique with the battery State Of Charge(SOC) limit logic to charge the battery in a controlled manner. The MPPT logic [8] used here actually forces the turbine to operate at optimum Tip Speed Ratio(TSR) and hence is parameter independent. The battery charging current is always continuous with very low ripple thus avoiding harmonic heating. The change over between the modes for battery charging is affected based on the actual value of the SOC. Further it also provides protection against turbine over speed, over loading, and over voltage at the rectifier output by using pitch control [9].
