Variability of solar power is a key driver in increasing the cost of integrating solar power into the electric grid because additional system resources are required to maintain the grid’s reliability. In this study, we characterize the variability in power output of six photovoltaic plants in the USA and Canada with a total installed capacity of 195MW (AC); it is based on minute-averaged data f...
The growth and development of human societies has always been parallel to the production and consumption of energy. Rapid and sustainable development in any country requires establishing a dynamic and stable balance between technical, economic, social and environmental categories while taking into account conditions that do not cause risks or reduce opportunities for progress. Energy and clean ...

In recent years, energy production by renewable sources is becoming very important, and photovoltaic (PV) energy has became one of the main renewable sources that is widely available and easily exploitable. In this context, it is necessary to find correct tools to optimize the energy production by PV plants. In this paper, by analyzing available solar irradiance data, an analytical expression f...
In this paper, the integrated unit commitment problem and gas network operation in which in the presence of renewable wind and solar power plants is modeled. Both wind and solar energy are variable sources of energy, but because solar energy is only available at certain times of the day, it has caused the load curve behavior to change. This change in load curve, known as the "duck curve, has ra...
Optical images of the nearby star Fomalhaut show a ring of dust orbiting the central star. This dust is in many respects expected to be similar to the zodiacal dust in the solar system. The ring displays a clear brightness asymmetry, attributed to asymmetric scattering of the central starlight by the circumstellar dust grains. Recent measurements show that the bright side of the Fomalhaut ring ...
Net energy metering tariffs have encouraged the growth of solar PV in the distribution grid. The additional variability associated with weather-dependent renewable energy creates new challenges for power system operators that must maintain and operate ancillary services to balance the grid. To deal with these issues power operators mostly rely on demand load forecasts. Electric load forecast ha...
Renewable energy types such as solar, wind or geothermal energy have been increasingly considered by different countries over the last few years in order to diversify power sources, reduce dependence on one single of energy, and achieve sustainable energy. On the other hand, rising prices of fossil fuels and the fact that they are finite, environmental pollution and evolution of the related tec...
Ulysses was launched in October 1990, and its Solar X-ray/Cosmic Gamma-ray Burst Experiment (GRB) has provided more than 13 years of uninterrupted observations of solar X-ray flare activity. Due to the large variation of the relative solar latitude and longitude of the spacecraft orbit with respect to the Earth, the perspective of the GRB instrument often differed significantly from that of X-r...
In this study a model-based control designed for the operation of a solar power plant is discussed. The simplified physically based model of the plant was developed on the basis of the energy balances including the solar insulation as an input, the heat transferred by the flow of the oil as a working media and the overall heat loss from the plant. The outlet temperature of the collector field i...
