This paper proposed the novel concept model for forecasting the PV power output. The model was used two meteorology to input model which are solar irradiance and module temperature. This model was improve the accuracy of model from simplified model is 1D5P by using the weight function. The proposed model was verified by comparison with measured data. The results showed that the model has high accuracy. The RMSE ranges from 0.02 to 0.07 and average RMSE is 0.04.

This papers shows the results of testing the power output of the solar PV system using silicon crystals used in the test. Then simulate the power output in the form of thirdgeneration model. The first generation model (1D5P) at a second series Weight Function Model and form a third model has been developed. The test system with 28 kWp The results show that the first form (1D5P) error of 14.40%. models the second error of 5.02% in the third form a models that has developed error of 1.05%.

In this paper, we introduced a P-buried (P<inf>b</inf>) layer under trench gate which relieved the electric field crowding in the Non Punch Through Trench gate Insulated Gate Bipolar Transistor (NPT-TIGBT) structure. The P<inf>b</inf> layer, with carrier concentration of 5 ×10<sup>16</sup> cm<sup>-3</sup>, was created underneath the trench gate within the n-drift layer. In this way, the concentration of electric field at the trench bottom corner decreased. As a result, the breakdown voltage characteristics of NPT-TIGBT improved. The structures were proposed and verified by T-CAD Sentuarus simulation. From the simulation results, the breakdown voltage increased by approximately 30% compared with conventional NPT-TIGBT. © (2013) Trans Tech Publications, Switzerland.

This research presents a method to improve data accuracy for the more efficient data management of the studied applications. The data accuracy was improved using the preciseness function learning model (PFL model). It contains a database in which the amount of data is more or less dependent on all of the possible behavior of the studied application. The proposed model improves data with functions obtained by optimizing curves to represent the data at each point, which estimate the database’s diffusion behavior, and functions can be built around all of the various forms of databases. The proposed model always updates its database after processing. It has been learning to optimize the processing precision. In order to verify the precision of the proposed model through its application to a PV system simulation model, the process’s database should contain at least one year. This is because the overall behavior of the PV power output in Thailand depends on the seasonal weather; Thailand has three seasons in a period of one year. The testing was performed by comparing the PV power output. The simulation results with the actual measurement data (12 MW PV system) can be divided into two conditions: the daily comparison and the seasonal PV power output. As a result, the proposed model can accurately simulate the PV power output despite the sudden daily climate change. The average nRMSE (normalized RMSE) of the proposed model is very low (1.23%), and ranges from 0.30% to 2.26%. Therefore, it has been proven that this model is very accurate.

This paper proposed the new simulation model for estimate PV Power Output of power plant in Thailand. Our development model were used the solar irradiance and module temperature as input of model. The model has develop by using one year measured data of focus area and verified by comparison with measured data. The results shown high accuracy and error about 1.11 %.

This paper describes a comparison of proposed model with simulation software and measurement data of PV power plant in Cambodia. The proposed model is based on behavior of PV module at a particular site. The parameters which affected to PV power output as solar irradiance and module temperature were used as input in this model. Weight function technics were used to improve accuracy of single diode five parameters (1D5P). It was found that the proposed model can improve the accuracy of PV power output estimation model.
