Direct Normal Irradiance Nowcasting methods for optimized operation of concentrating solar technologies (DNICast)

Concentrating solar technologies (CST) have proven to be very efficient sources of clean power for the electrical grid. CST include thermodynamic machines, such as the concentrating solar power (CSP: parabolic troughs, solar towers, Fresnel collectors, parabolic dishes…), or concentrating photovoltaics (CPV).

The efficient operation of CST requires reliable forecasts of the incident irradiance for two main reasons:

–             First, to yield a better management of the thermodynamic cycle

–             Second, the electricity production can be optimally connected to the grid.

Forecasts are made by several techniques, which have their own merits and drawbacks. The uncertainty in the forecast of the Direct Normal Irradiance (DNI) is still too large and must be reduced.

The DNICast project, brings a series of innovative components which would advance current state-of-the-art in a number of ways. These innovations can be clustered in terms of methodological progress, geographical extension and a participatory approach through the involvement of stakeholders and potential end-users.
