Title: Identification of periods of clear sky irradiance in time series of GHI measurements

Abstract

In this study, we present a simple algorithm for identifying periods of time with broadband global horizontal irradiance (GHI) similar to that occurring during clear sky conditions from a time series of GHI measurements. Other available methods to identify these periods do so by identifying periods with clear sky conditions using additional measurements, such as direct or diffuse irradiance. Our algorithm compares characteristics of the time series of measured GHI with the output of a clear sky model without requiring additional measurements. We validate our algorithm using data from several locations by comparing our results with those obtained from a clear sky detection algorithm, and with satellite and ground-based sky imagery.

Automatic Detection of Clear-Sky Periods From Irradiance Data

Journal Article Ellis, Benjamin H. ; Deceglie, Michael ; Jain, Anubhav - IEEE Journal of Photovoltaics

© 2019 IEEE. Recent degradation studies have highlighted the importance of considering cloud cover when calculating degradation rates, finding more reliable values when the data are restricted to clear sky periods. Several automated methods of determining clear sky periods have been previously developed, but parameterizing and testing the models has been difficult. In this paper, we use clear sky classifications determined from satellite data to develop an algorithm that determines clear sky periods using only measured irradiance values and modeled clear sky irradiance as inputs. This method is tested on global horizontal irradiance (GHI) data from ground collectors at sixmore »« less

Global horizontal irradiance clear sky models : implementation and analysis.

Technical Report Stein, Joshua S ; Hansen, Clifford W ; Reno, Matthew J

Clear sky models estimate the terrestrial solar radiation under a cloudless sky as a function of the solar elevation angle, site altitude, aerosol concentration, water vapor, and various atmospheric conditions. This report provides an overview of a number of global horizontal irradiance (GHI) clear sky models from very simple to complex. Validation of clear-sky models requires comparison of model results to measured irradiance during clear-sky periods. To facilitate validation, we present a new algorithm for automatically identifying clear-sky periods in a time series of GHI measurements. We evaluate the performance of selected clear-sky models using measured data from 30 differentmore »« less

Automatic Detection of Clear-Sky Periods Using Ground and Satellite Based Solar Resource Data

Conference Ellis, Benjamin H. ; Deceglie, Michael G ; Jain, Anubhav

Solar resource availability and variability are important aspects of monitoring performance of photovoltaic installations. For example, recent degradation studies have highlighted the importance of considering cloud cover when calculation degradation rates. With this in mind, we present a method for optimizing clear sky detection algorithms given only modeled clear sky irradiance and ground-measured irradiance values. This method is tested on global horizontal irradiance (GHI) data from ground collectors at six sites across the US and was trained against clear sky classifications determined from satellite data. Thirty models were optimized on each individual site at GHI data frequencies of 1, 5,more »« less

A Posteriori Clear-Sky Identification Methods in Solar Irradiance Time Series: Review and Preliminary Validation Using Sky Imagers

Journal Article Gueymard, Christian A. ; Bright, Jamie M. ; Lingfors, David ; ... - Renewable and Sustainable Energy Reviews

This study examines all known methods that have been proposed in the literature to identify clear-sky periods in historical solar irradiance time series. Two different types of clear-sky detection (CSD) methods are discussed: those (16 total) that attempt to isolate periods of 1-min or more cloudless conditions, and those (5 total) that only attempt to detect clear-sun periods. All methods are found to rely on a diversity of inputs and on a variety of tests that typically examine the smoothness of the temporal variation of global and/or direct irradiance. Using samples of a few days with variable cloudiness, it ismore »« less

A Physics-based Smart Persistence model for Intra-hour forecasting of solar radiation (PSPI) using GHI measurements and a cloud retrieval technique

Journal Article Kumler, Andrew ; Xie, Yu ; Zhang, Yingchen - Solar Energy

Short-term solar forecasting models based solely on global horizontal irradiance (GHI) measurements are often unable to discriminate the forecasting of the factors affecting GHI from those that can be precisely computed by atmospheric models. Here, we introduce a Physics-based Smart Persistence model for Intra-hour forecasting of solar radiation (PSPI) that decomposes the forecasting of GHI into the computation of extraterrestrial solar radiation and solar zenith angle and the forecasting of cloud albedo and cloud fraction. The extraterrestrial solar radiation and solar zenith angle are accurately computed by the Solar Position Algorithm (SPA) developed at the National Renewable Energy Laboratory (NREL).more »« less
