IEA PVPS Task 16 has released a detailed study assessing the added value of combining solar irradiance data and forecasts. This research, conducted by five participants in eight European sites, aims to propose to the solar forecasters community a comprehensive benchmarking exercise related to intra-day and intra-hour solar irradiance forecasts.
Study Overview
Despite the growing awareness in academia and industry of the importance of solar probabilistic forecasting for further enhancing the integration of variable photovoltaic power generation into electrical power grids, there is still no benchmark study comparing a wide range of solar probabilistic methods across various local climates. Having identified this research gap, experts involved in the activities of IEA PVPS T16 agreed to establish a benchmarking exercise to evaluate the quality of intra-hour and intra-day probabilistic irradiance forecasts.
