With exponential growth in in the U.S. utility-scale photovoltaic market, high resolution solar irradiance data and appropriate spatial-temporal models are required to determine the true impact of solar power variability on the grid. This paper describes a new and economical Data Acquisition System (DAS) to collect high resolution solar power data required for high penetration PV integration studies...
Photovoltaic energy is susceptible to high variability, caused by passing clouds that may affect a site's daily energy production substantially. The reduction in solar variability due to geographic diversity was compared for a large central PV plant and small distributed PV plants using a multistep approach. At short timescales, geographic smoothing offers a strong benefit, which decreases with longer...
A common critique of photovoltaic energy is the susceptibility of the systems to high variability— passing clouds can affect a site's day-to-day energy production substantially. This research developed a tool to simulate photovoltaic energy systems in several scenarios throughout the state of Florida and quantifies the hour-to-hour impact of these systems on the statewide generation mix using 11 years...
The basic design is made for a 250 KW solar power plant. The main element of the plant is the collectors. Base on system simulation, a parabolic collector constructed and tested for one year. The model is first validated with experimental measurement and a detail numerical model is also developed to study effects of various optical properties of mirrors and receiver on the thermal performance of the...
With taking into special consideration the importance of the competition which exists in the world to utilize new energies; and also in agreement with our country from the viewpoint of superficies and duration of solar radiation, it is necessary to use such energy as much as possible. Therefore, in this article, Shiraz Linear Parabolic Solar Power Plant has been used to survey as a pattern. The most...
