However, this research aims to enhance the efficiency of solar power generation systems in a smart grid context using machine learning hybrid models such as Hybrid Convolutional-Recurrence Net (HCRN), Hybrid Convolutional-LSTM Net (HCLN), and Hybrid Convolutional-GRU Net (HCGRN).
It can be found from M3 that the variable Efficiency has a positive influence on solar generation, which is statistically significant as well. It shows that when we further control other explanatory variables, the efficiency of solar power generation has a significant positive impact on the scale of solar power generation in the country.
Utility type also affects the architecture of solar PV grid-integrated configuration, whether single phase or three phase. The single-stage and double-stage power processing solar PV integrated configurations are determined by the number of power processing stages involved in each system.
The different solar PV configurations, international/ national standards and grid codes for grid connected solar PV systems have been highlighted. The state-of-the-art features of multi-functional grid-connected solar PV inverters for increased penetration of solar PV power are examined.
Furthermore, the found that real system’s PV module, inverter and system efficiency was 11.27%, 97.49% and 11.27% respectively. PVsyst estimates a higher system efficiency as 11.39% than real system.
To manage the flow of power from the solar plant to the grid, the project used a substation that contained transformers from ABB company. Table 2 Present configuration and prospective growth strategies of solar power facilities. The substation also contained other electrical equipment such as switchgear, protection relays, and control systems 26.
