I. INTRODUCTION

Big Data bring new opportunities to modern society andchallenges to data scientists. In the age of digital world, allthe information is being stored in the cloud. Also withdigitization of various power sector has increased the flowof sensor data and the cloud computing. The first definitionof Big Data comes from Merv Adrian, “Big data exceedsthe reach of commonly used hardware environments andsoftware tools to capture, manage, and process it within atolerable elapsed time for its user population”[1]. In year2014 IBM has introduced the HyRef (Hybrid RenewableEnergy Forecasting) system for the wind and solar power.By utilizing local weather forecasts, HyRef can predict theperformance of each individual wind turbine and estimatethe amount of generated renewable energy. This level ofinsight will enable utilities to better manage the variablenature of wind and solar, and more accurately forecast theamount of power that can be redirected into the power gridor stored. It will also allow energy organizations to easilyintegrate other conventional sources such as coal andnatural gas.

However, this area of research is very new andpromising and carries lot of financial potential. Manyresearch communities are trying to develop a sophisticatednetwork comprised with big data analytics. In addition,solar and wind power forecasting is developed according tothe soft-modeling of the system with the sensor data withvarious level of weather analysis. Several researches haveproven the effectiveness of big data in health care andfinancial forecasting. International Data Corporation havebeen paid by Xerox, Univac and Burrough companies forpredicting future of computer technology in year 1999.[2]Various survey and analysis has been done by the IDC from1964 to till date.

In figure 4 effect of cloud makes a great impact on theconversion efficiency of converter. To achieve good levelof power conversion one need to consider other variable ofsolar system.

Figure 5 P-V characteristic for different irradiance

Fig-5 shows the PV characteristic of a system for differentirradiance level during a day. In a day irradiance variesaccordingly for the various position of sun. There arevarious mathematical expressions for position of sun forthe day and night.

In fig 6 power vs output voltage is presented for thedifferent temperature level. In this curve it is very muchclear that the temperature variation greatly affect the outputvoltage of solar PV panel.

It is noteworthy that effectiveness of any power trackingalgorithm is function of different variable as voltagecurrent and power. However, for better control andextraction of power from the solar panel requires the nearto exact estimation of temperature, irradiance and the windspeed.
