Figure 2: Data & Analysis in New and Renewable Energy - Forecast
Due to the growing demand of renewable energy, photovoltaic (PV) generation systems have increased considerably in recent years. Solar Insolation forecasting technology plays a very important role since depending on the accuracy of prediction, the amount of economic benefits from solar energy is significantly different. To cater the need of PV farm operators, Next 72 hours forecast (15-min interval) of solar insolation and temperature, next 72 hours wind and relative humidity forecast (3 hours interval) are generated on daily basis using Numerical Weather Predication model (NWP). These forecast datasets are published as OGC (Open Geospatial Consortium) compliant Time enabled Web Map Services (WMS) and animation for same is also available on VEDAS.

Figure 2.1.3: Wind Forecast - Wind energy :
Wind energy is the second fastest growing source of electricity in the world. Harnessing energy from wind and converting into electricity has several advantages. So to exploit wind energy from vast coastline of India which cover 7600 km and land, the VEDAS web-portal provides information on monthly wind energy potential. The ocean wind energy is derived from scatterometer data. India’s Oeansat -2 OSCAT, an active Ku-band (13.515 GHz) microwave payload, and QSCAT provide data to retrieve wind speed and direction. OSCAT has a spatial resolution of 50 kmThe interface is designed to assess monthly average wind power potential. Wind forecast for next 72 hours at 3-hour interval generated from Weather Research Forecast (WRF) model is also available under forecast tab.

Wave Energy :
Ocean wave has enormous energy potential and it is harnessed from sea waves. It is one of the most sustainable energy source. The rigorous vertical motion of sea waves contains lot of kinetic energy which can be further use for electricity generation, desalinization of water etc. To exploit wave energy, VEDAS provides information about wave height, wave power and wave periods in form of WMS Services.
