Evaluation of performance for day-ahead solar irradiance forecast using numerical weather prediction

Journal of Renewable and Sustainable Energy, Journal Year: 2024, Volume and Issue: 16(4)

Published: July 1, 2024

Numerical weather prediction (NWP) is widely used for day-ahead solar irradiance forecast, which essential applications in energy market and management of different scales ranging from public level to civil level. In the literature, many NWP correction methods have been proposed obtain more accurate forecast. However, when facing real-world scenarios, it crucial efficiently design corresponding schemes, require a detailed reliable error evaluation foundation. To solve this problem, performance Global Horizontal Irradiance (GHI) forecast evaluated under conditions seasons. The statistical analysis was conducted at each time day GHI with both publicly available datasets actual field dataset, aiming explore characteristics forecasts. results demonstrate variations across diverse seasons, indicates that future corrections should be developed For conditions, forecasts lowest accuracy during overcast followed by cloudy while highest observed sunny conditions. Moreover, overestimations are likely occur generally winter. Additionally, we summarized some common This study provides useful information improving efficiency works stable operation power systems.

The future of solar forecasting in China

Journal of Renewable and Sustainable Energy, Journal Year: 2023, Volume and Issue: 15(5)

The current grid code in China regard to solar forecasting is, my opinion, underdeveloped, especially contrast the rate at which photovoltaics are being installed. As such, explaining limitations of and resetting pathways improve it thought utilitarian for those scientists policymakers who responsible or aware but have not themselves worked on problem forecasting. In this perspective article, I should first explain with respect China's perceived deficiencies research practices, then outline a five-stage workflow that could completely mitigate situation. Among other things, over-reliance accuracy as basis gauging goodness forecasts is identified root cause status quo, thus, advocate holistic forecast verification procedure encompasses consistency, quality, value. With mind, proposed better integration purposes relies effective information flow among weather department, operators, individual plant owners, inline code. What goes beyond proposal further introduces couple concepts called “hierarchical reconciliation” “firm forecasting,” new able eliminate errors wholly, thus making power dispatchable system level. slight premium incurred, now possible manage plants, variable renewables general, same style managing conventional fire-powered generators.
