This paper presents an optimized model that combines the Intelligent Water Drop (IWD) optimization algorithm and a neural network (NN) for maximum power point tracking (MPPT) in photovoltaic (PV) applications. The proposed approach demonstrates superior performance compared to conventional methods, including Fuzzy Logic Control, Perturb and Observe (P&O), Particle Swarm Optimization (PSO), Genetic Algorithm (GA), and Incremental Conductance (INC) control. The enhanced model improves adaptability and convergence due to the optimization capabilities of the IWD algorithm and leverages the predictive characteristics of the NN for faster and more accurate tracking. The results indicate that this model offers significant potential for future-generation PV systems, particularly in solar energy applications.

In this paper, a controller is designed for a hybrid power system using a soft computing technique. The power system consists of a PV system, fuel cell, aqua electrolyzers, diesel engine generator, and a battery energy storage system. The system's frequency is controlled by a proportional-integral (PI) controller and a proportional-integral-derivative (PID) controller. A powerful optimization technique, called the Gorilla Troops Optimizer (GTO), is used to optimize the controller gains of the proposed hybrid power system. The system responses with GTO optimization-based controllers are compared with those using the Particle Swarm Optimization technique. Finally, the frequency responses show that the GTO-based controller is more effective in mitigating frequency variations in the system.
