Abstract
Nowadays Grid connected photovoltaic (PV) systems increases its influence in Indian power system. The current rise in load and demand means that linked power networks are essential. The efficiency of a load is significantly impacted by power quality issues, especially when it comes to frequency. The power system’s frequency and tie-line power should be as close as possible to the anticipated specifications. This article proposes artificial raindrop method with proportional- integral (PI) controller, to manage the load frequency control (LFC) of a PV-thermal-thermal interconnected three-area power system. A meta-heuristic method that takes inspiration from natural rainfall is the proposed artificial raindrop algorithm. A comparison is made between the suggested system and standard PI controller. A number of loads are simulated using Matlab to assess the full system. To validate the performance of proposed system, it is compared with the LFC using PI and fuzzy gain scheduling controller. Matlab is used to evaluate the entire system with varying loads. Take into account area 1 in 10% load perturbation: FGS reduces frequency deviation undershoot by 22% compared to the PI controller, while the ARD algorithm reduces it by 32%, where PI results in an undershoot of 0.1781 Hz.
