Abstract: Hybrid power plants, integrating multiple renewable energy sources such as solar, wind, and energy storage systems, offer a sustainable solution to modern energy challenges. However, the variable and intermittent nature of renewable sources demands sophisticated control mechanisms to ensure grid stability, energy efficiency, and economic viability. Model Predictive Control (MPC), particularly Nonlinear Model Predictive Control (NMPC), has emerged as an effective optimization framework for managing the complex dynamics and operational constraints of hybrid energy systems. This paper discusses the application of NMPC in hybrid power plant optimization, focusing on its ability to predict future energy demands and renewable generation. NMPC dynamically adjusts the dispatch of power between renewable sources, energy storage, and the grid by solving a nonlinear optimization problem in real-time. The control strategy maximizes renewable energy utilization, reduces operational costs, and ensures system reliability while accounting for constraints such as battery state-of-charge, inverter capacity, and grid stability. Key advancements in NMPC, including machine learning-enhanced forecasting, multi-objective optimization, and integration with smart grid technologies, are highlighted. These advancements enable hybrid power plants to operate more efficiently and flexibly, even under rapidly changing conditions. The paper concludes that NMPC is a critical tool for future-proofing hybrid renewable energy systems, allowing them to meet both grid-connected and off-grid demands while optimizing performance and sustainability.
