Parameter Estimation for Single Diode Models of Photovoltaic Modules
Abstract
Many popular models for photovoltaic system performance employ a single diode model to compute the I  V curve for a module or string of modules at given irradiance and temperature conditions. A single diode model requires a number of parameters to be estimated from measured I  V curves. Many available parameter estimation methods use only short circuit, o pen circuit and maximum power points for a single I  V curve at standard test conditions together with temperature coefficients determined separately for individual cells. In contrast, module testing frequently records I  V curves over a wide range of irradi ance and temperature conditions which, when available , should also be used to parameterize the performance model. We present a parameter estimation method that makes use of a fu ll range of available I  V curves. We verify the accuracy of the method by recov ering known parameter values from simulated I  V curves . We validate the method by estimating model parameters for a module using outdoor test data and predicting the outdoor performance of the module.

Oasis: Parameter estimation system for aquiferrestoration models. User's manual. Version 2. 0. Report for October 1987September 1989
OASIS, a decision support system for ground water contaminant modeling, has been developed for the EPA by Rice University, through the National Center for Ground Water Research. As a decision support system, OASIS was designed to provide a set of tools which will help scientists and modelers assess ground water contamination problems. OASIS is a graphical decision support system and was developed around BIOPLUME II, a numerical model which simulates the aerobic degradation of dissolved hydrocarbons in ground water. The OASIS system was developed in the HyperCard environment and, unlike traditional software, contains extensive documentation and help onscreen. Question markmore » 
Parameter Estimation for Thurstone Choice Models
We consider the estimation accuracy of individual strength parameters of a Thurstone choice model when each input observation consists of a choice of one item from a set of two or more items (so called top1 lists). This model accommodates the wellknown choice models such as the Luce choice model for comparison sets of two or more items and the BradleyTerry model for pair comparisons. We provide a tight characterization of the mean squared error of the maximum likelihood parameter estimator. We also provide similar characterizations for parameter estimators defined by a rankbreaking method, which amounts to deducing one ormore » 
Parameter estimation in structural dynamics models
A method is presented for the estimation of parameters in structural dynamics models. The key features of the method are as follows: estimates are obtained for the intrinsic (physical) parameters of the original model; the procedure is useful for structural dynamics problems limited to medium size, e.g., 1 to 200 degrees of freedom, where only a few, e.g., 1 to 10 key parameters are known; a constrained version of the Discrete, Iterated Extended Kalman Filter for parameter estimation is employed to obtain the estimates, utilizing frequency response function data as the measurements; a slight variation of modal synthesis transformation methods,more » 
Determination of optimum mounting configurations for flatplate photovoltaic modules based on a structured field experiment and simulated results from PVFORM, a photovoltaic system performance model
The performance of a photovoltaic (PV) system is affected by its mounting configuration. The optimal configuration is unclear because of lack of experience and data. Sandia National Laboratories, Albuquerque (SNLA), has conducted a controlled field experiment to compare four types of the most common module mounting. The data from the experiment were used to verify the accuracy of PVFORM, a new computer program that simulates PV performance. PVFORM was then used to simulate the performance of identical PV modules on different mounting configurations at 10 sites throughout the US. This report describes the module mounting configurations, the experimental methods used,more »
