The rapid deployment of variable renewable energy (VRE), such as solar photovoltaic (PV) generation, increases the system real-time power imbalance because of the random variation and uncertainty of VRE power generation. To manage this, system operators have two potential options: the first is a fast real-time generation dispatch to schedule

(2020) calculated solar PV power generation globally by applying the PVLIB-Python solar PV system model, By converting solar power into electricity, we calculated the annual mean capacity factors (CFs) for solar PV power at these stations with installation configurations similar to recent studies (Li et al., 2020). Three scenarios of different mounting
This paper proposes a novel method for the real-time prediction of photovoltaic (PV) power output by integrating phase space reconstruction (PSR), improved grey wolf optimization (GWO), and long short-term memory (LSTM) neural networks. The proposed method consists of three main steps.
The theoretical potential for solar PV generation was calculated using an open-source PVLIB model (Sub-section 2.1), and the land suitability factor was determined based on the land and resource factors (Sub-section 2.2). A schematic diagram for depicting the methodological framework of potential assessment was presented in Fig. 1.
In PV systems, power generation calculation considers both solar radiation potential and PV technical potential, with the former based on GHI from NASA, while the latter based on PV module area, module conversion efficiency, and integrated efficiency.
Based on the PV module area method and the regional power grid carbon emission factor, the PV power generation was calculated to be 238.65 TWh, equivalent to reducing coal consumption by 72.77 million tons and carbon emissions by 149.63 million tons.
The dataset includes daily and hourly power generation data from fossil fuels (coal, natural gas, and oil), nuclear, hydro, wind, solar, geothermal, biomass, and other renewables for 37 countries, which covers around 70% of the global power production and 68% of global power-related CO 2 emissions.
However, the amount of solar PV power generation as a proportion of total electricity generation remains very low, at only approximately 3.42% in 2020 (NEA, 2021).
According to the projection of Chinese scholar, the total electricity demand of China will reach at least 15 PWh by 2060, and thus 20.6% of the total technical potential of solar PV power generation can be developed to meet this electricity demand. Fig. 11.
