Photovoltaic power generation is a technology that uses solar panels to convert light energy directly into electricity but is not equipped with an energy storage system, generates unstable...
Notably, the instability of solar energy resources varies across regions, with the Yangtze River Basin and the southeast coastal areas experiencing greater instability compared to the Qinghai-Tibet Plateau, Northwest China, Inner Mongolia, and other regions.
Solar energy is intermittent and variable in output, which leads to changes in grid frequency and voltage. Numerous variables, including the time of day and the weather, contribute to this unpredictability. The system may become unstable due to the erratic energy supply, which might result in equipment damage, interruptions, and power outages.
In addition to the expected periodic fluctuations, extreme unexpected solar energy abnormal events will cause a stronger risky impact on photovoltaic power generation, which deserves more attention in energy safety.
Moreover, with high convective intensity and increased climate variability, solar energy anomalies are prone to occur. Prolonged periods of heavy rainfall and sudden abnormal weather conditions disrupt the stability of solar radiation reception, elevating the likelihood of deviations from expected solar radiation levels.
The intermittency of solar power generation is one of the main obstacles to its integration into the grid. There can be variations in the quantity of energy generated by solar energy because it is dependent on the weather and time of day.
In the production of power with solar energy, the fluctuations in the supply and demand of energy for a particular place can cause instability in the grids. These fluctuations occur because the sunlight intensity in an environment with homes using solar panels, for example, varies from time to time.
