Special Issue Information

Dear Colleagues,

Concerning the cost-effectiveness and sustainability of wind power as a clean fuel source and the growing rate of the energy systems demand, the studies on wind energy have attracted attention from researchers from all around the world. The International Renewable Energy Agency has reported that global installation of the wind power capacity has raised by a factor of almost 75 in the past two decades, which increased from 7.5 GW in 1997 to some 564 GW in 2018, considering both onshore and offshore turbines. On the other hand, the potential of the energy in waves off of coastlines has resulted in technical and operational challenges arising for energy systems. As reported by The United States Energy Information Administration (EIA), it is estimated that United States has a potential of as much as 2.64 trillion KWh power production using waves off coasts, which is almost 64% of the United States electricity generation in 2019. The proposed research topic of the current Special Issue concentrates on the potential of wind and wave energy in future energy grids, including, but not limited to, the global potential of wind power, physical and technological limits of wind power, evaluation of global wind power, assessing the global wind energy resources, the rise of modern wind power, optimal allocation of wind turbines in energy grids, the global potential of wave energy, physical and technological limits of wave energy, studying the global wave energy resources, and the allocation of wave generation plants.

The growing energy demand has increased the consumption of hydrocarbons in developing countries such as Mexico, which has contributed to accelerating global warming. Although Mexico has suitable offshore wind energy harvesting sites, technical assessments to identify technologies to be placed in specific locations are scarce. In Mexico, offshore wind resources are found in depths larger than 50 m. There, floating platforms are convenient for harnessing wind energy. This work presents a technical evaluation of offshore wind energy in one of the regions with a higher availability of wind resources on the Mexican coasts, the Tehuantepec Gulf, in the Pacific Ocean. First, a specific location is chosen to evaluate its maritime conditions and theoretical wind energy potential. Next, the performance of a floating offshore wind turbine platform has been investigated numerically using potential flow simulations. The motions of the platform were analyzed for different drafts when subjected to different environmental conditions in the evaluated region. These conditions include wave and wind scenarios with the highest probability of occurrence and the most extreme ones. From the evaluation of the platform dynamics in these scenarios, it was possible to identify the general working conditions of the platform. Results showed that the proposed FOWT could be suitable to be deployed in the region of interest for the most probable environmental conditions, presenting a possible energy production within 3–4 MW, approximately. However, motion stabilization should be required when subjected to extreme environmental conditions as the structure could significantly increase its surge and pitch motions. The simplified approach employed in this work can help perform the following steps in technical or practical resource assessments of wind energy in other places in Mexico or similar developing regions.

Nowadays, the renewable energy sources in microgrids (MGs) have high participation to supply the consumer’s demand. In such MGs, the problems such as the system frequency stability, inertia, and damping reduction are threatened. To overcome this challenge, employing the virtual inertia control (VIC) concept in the MG structure could be considered as a viable solution to improve the system frequency response. Hence, this work proposes a novel modeling for VIC in an islanded MG that provides simultaneous emulation of the primary frequency control, virtual inertia, and damping. To show the efficiency of the proposed technique, a comparison is made between the dynamic performance of the proposed VIC and conventional VIC under different scenarios. The results indicate that the proposed VIC presents superior frequency performance in comparison with conventional VIC. In addition to VIC modeling, a new cascade controller based on three-degrees of freedom and fractional-order controllers (FOCs) is proposed as an MG secondary controller. The effectiveness of the proposed controller is compared to tilt-integral-derivative and FO proportional-integral-derivative controllers. The Squirrel search algorithm is utilized to obtain the optimal coefficients of the controllers. The results demonstrate that the proposed controller improves the MG frequency performance over other controllers. Eventually, the sensitivity analysis is performed to investigate the robustness of the proposed controller in the face of the variations of the parameters. Full article

Statistical characteristics of the wind speed in the Samaria region of Israel have been analyzed by processing 11 years of wind data provided by the Israeli Meteorological Service, recorded at a 10 m height above the ground. The cumulative mean wind speed at a measurement height was shown to be 4.53 m/s with a standard deviation of 2.32 m/s. The prevailing wind direction was shown to be characterized by a cumulative mean azimuth of 226° with a standard deviation of 79.76°. The results were extrapolated to a 70 m height in order to estimate wind characteristics at the hub height of a medium-scale wind turbine. Moreover, Weibull distribution parameters were calculated annually, monthly, and seasonally, demonstrating a good match with histogram-based statistical representations. The shape parameter of the Weibull distribution was shown to reside within a narrow range of 1.93 to 2.15, allowing us to assume a Rayleigh distribution, thus simplifying wind turbine energy yield calculations. The novelty of the current paper is related to gathering wind statistics for a certain area (Samaria), and we are not aware of any published statistics regarding wind velocity and direction in this area. These data may be interesting for potential regional wind energy development in which the obtained Weibull distribution could be used in calculations for the expected power generation of particular turbines with a known power dependence on velocity. We have given an example of these calculations for three different types of turbines and obtained their yield in terms of electric power and economic value. We also point out that the fact that realistic wind velocity statistics can be described well by an analytic formula (Weibull distribution) is not trivial, and in fact, the fit may have been poor.
