Optimization of Hybrid Renewable Energy Systems: Integrating Turbine, Solar, and Battery Systems in Water Supply Systems

Abstract Submission: This paper introduces an innovative optimization model designed to determine the optimal sizing and operational strategy of a hybrid renewable energy system combining turbine, solar, and battery storage technologies. The system is intended to enhance energy efficiency and cost-effectiveness by maximizing energy production from renewable sources, minimizing operational costs, and adapting to dynamic electricity pricing structures.
The core of this model is the design of a turbine system modeled on a reference turbine already with known characteristics. Using well-established affinity laws, we expand the system's potential by creating a spectrum of alternative turbine configurations. These configurations are customized to meet the varying operational demands of the system, allowing for an optimal balance between capital investment and operational efficiency. The novelty of the model lies not only in its hybrid system design but also in its optimization approach. The model seeks to find the best combination of turbine size, solar panel capacity, and battery storage to ensure optimal performance over representative days from different seasons. These representative days capture the system's response to seasonal variations in solar radiation, water demand, and electricity prices. By incorporating these variations into the optimization process, the model ensures that the system is adaptable to both high-demand and low-demand periods, making it robust across the entire operational year.
A critical component of the model is its integration of real-world pricing structures for energy production and consumption. It incorporates dynamic pricing models, allowing the system to strategically adjust its operation to minimize costs and maximize revenue from energy sales. In addition to its sophisticated pricing mechanisms, the model also accounts for realistic capital and operational costs. The result is an economically viable system that balances short-term operational savings with long-term investment returns, ensuring that the system is both cost-effective and sustainable.
