“…The dynamic Nomenclature q density of air (kg/m 3 ) x rotational speed of the turbine (rad/s) h turbine angle to the wind direction (°) and static torques are measured within the uncertainty level of ±2%. The rotational speed of the turbine is recorded by a digital tachometer having an accuracy of ±1%, whereas the wind speed is measured with the help of a hot wire anemometer having an accuracy of ±2%.…”

“…In this context, research in the field of wind energy is becoming particularly important [1][2][3][4][5][6]. Although considerable progress has been achieved in the area of horizontal axis wind turbines, the available technical designs of vertical axis wind turbines are not yet satisfactory for the development of low cost reliable wind energy converters for conditions corresponding to the off-grid power generation at low wind speeds.…”

“…Solution of this problem is to make use of renewable sources of energy. In this context, it is very important to do much more research effort in this field of wind energy [3][4][5][6][7][8]. The studies dealing with the vertical axis wind turbine for development of low cost reliable wind energy converters needed for the off-grid power generation at low wind speed are still not reasonable compared to those dealing with the horizontal axis wind turbine.…”

The purpose of this study is to make a numerical simulation of the previously reported experimental results dealing with the performance of the conventional semi-circular two bladed SSWT based on the relationships between torque coefficients and different tip speed ratios λ, to be in comparison with the CFD results. The present investigation demonstrates absolute error growth of order ~ 0.01 within specified range of λ between CFD and the available experimental data.

“…The heat sector is the first one to be considered in SEP, particularly exploiting flexibilities in the heat storage of CHP [64,148,154]. A joint power-heat SEP has become more relevant with time [67,134,135,143,151,153,156,158,159]. For example, down to the level of individual buildings, there are clear examples of ESS able to support DSM mechanisms and to provide flexibility.…”

Expansion planning models are often used to support investment decisions in the power sector. Towards the massive insertion of renewable energy sources, expansion planning of energy storage systems (SEP-Storage Expansion Planning) is becoming more popular. However, to date, there is no clear overview of the available SEP models in the literature. To shed light on the existing approaches, this review paper presents a broad classification of SEP, which is used to analyze a database of about 90 publications to identify trends and challenges. The trends we found are that while SEP was born more than four decades ago, only in the last five years increasing research efforts were put into the topic. The planning has evolved from adequacy criteria to broader targets, such as direct costs, mitigation of CO2 emissions, and renewable integration. The modeling of the network, power system, energy storage systems (ESS), and time resolution are becoming more detailed. Uncertainty is often considered and the solution methods are still very diverse. As outstanding challenges, we found that (1) the large diversity of ESS, in contrast to conventional generation technologies, and (2) the complex lifetime and efficiency functions need to be addressed in the models. (3) Only a high temporal and spatial resolution will allow for dimensioning the challenge of integrating renewables and the role of ESS. (4) Although the value of ESS lies beyond shifting energy in time, current SEP is mostly blind to other system services. (5) Today, many flexibility options are available, but they are often assessed separately. In the same line, although cross-sectorial (power, heat, transport, water) SEP is becoming more frequent, there are many open tasks towards an integrated coordination. The planning of future energy systems will be multi-sectorial and multi-objective, consider the multi-services of ESS, and will inherently require interdisciplinary efforts.
