The increased power demand needs the installation of more power-generating units. Apart from conventional power generating stations based on fossil fuel combustion, recently solar power generating stations have attracted a large stake due to various advantages. However, the increased power generation also needs to be focused on various factors like stability, and reliability of the grid system leading to putting more emphasis on active power control techniques. This article reviews different active power control methods including conventional and flexible horizons. The focus of this article is to analyze the reliability factor while extracting power from solar plants. Maximum power point tracking (MPPT) is a well-known strategy for the maximum utilization of solar energy. However, as the dependency on solar energy rises the conventional control strategy needs to be modified for active grid participation of the PV systems. This can be performed by incorporating Flexible Power Point Tracking (FPPT) control strategies instead of MPPT. In this article, a comparison of the two techniques has been performed to choose the best method based on the requirement. Further, the impact of both systems on the grid system has been briefed in this article. Also, benchmarking has been proposed from the analysis to switch over between the modes depending on the power availability.
