A taxonomy of short‐term solar power forecasting: Classifications focused on climatic conditions and input data

Abstract

A review of the state‐of‐the‐art in short‐term Solar Power Forecasting (SPF) methodologies is presented in this paper. Over the last few years, developing and improving solar forecasting models has been the main focus of researchers, considering the need to efficiently increase their forecasting accuracy. Forecasting models aim to be used as an efficient tool to help with the stability and control of energy systems and electricity markets. Intending to further comprehend the factors affecting the quality of SPF models, this paper focuses on short‐term solar forecasting methodologies since they pose a crucial role in the daily operation and scheduling of power systems, since they focus on forecasting horizons typically ranging from 1 h to 1 day. The reviewed works are classified according to the climatic conditions, technical characteristics, and the forecasting errors of the different methodologies, providing readers with information over various different cases of SPF. Considering the need to improve the SPF efficiency, such classifications allow for important comparative conclusions to be drawn, depending on the location of each case and the meteorological data available. Future directions in the field of short‐term solar power forecasting are proposed considering the increasing development of SPF models’ architecture and their field of focus.

Economic Analysis of Rooftop Based On-Grid and Off-Grid Photovoltaic Systems in Equatorial Area

“…Leveraging advanced software tools and algorithms, the study delves into the performance of diverse PV system configurations, accommodating variables such as building orientation, shading impacts, and the unique geographical attributes of Padang's university campus. Complementing this analysis is an economic evaluation, which gauges the financial viability, payback period, and return on investment (ROI) of the proposed PV installation system within the operational framework of the university (Bazionis et al, 2023) (Hamdani et al, 2021).…”

A Review of Solar Power Scenario Generation Methods with Focus on Weather Classifications, Temporal Horizons, and Deep Generative Models

“…Furthermore, the installation of solar photovoltaics (PVs) is relatively simple. The global installed solar power capacity was approximately 942 GW by the end of 2021, with its annual increase rate surpassing that of onshore wind power [2]. The total installed solar capacity is expected to increase significantly due to the cost reduction in PVs production and continuous technological Energies 2023, 16, 5600 2 of 29 advancements.…”

“…A systematic review of SPF methods, evaluation metrics, optimization, and data pre-processing techniques, was provided in [5] and extended in [6] to include hybrid methods. In [2], a taxonomy of short-term SPF methods based on climatic conditions was introduced. In recent years, the focus of deterministic SPF has shifted toward machine learning.…”
