SHORT-TERM ENERGY OPTIMIZATION OF A MIXED THERMO-HYDRO POWER SYSTEM WITH EMPHASIS ON HYDROELECTRIC PLANT EXPLOITATION

ABSTRACT
The paper focuses on the optimization of a mixed thermo-hydro power system production, with a particular emphasis on a comprehensive overview of mathematical models and optimization methods, addresses the challenges and opportunities in enhancing energy efficiency and reliability. The delves into optimizing hydro power systems across various time horizons: long-term, mid-term, and short-term planning. A detailed analysis is provided on the division of power outputs for individual generating units during plant operation, ensuring optimal performance across different scenarios. A low-head hydro power plant case study explores short-term optimization, crucial for meeting daily load demands. This section highlights the operational strategies and decision-making processes necessary for maintaining a balance between energy production and system reliability. In addition, the paper investigates energy optimization strategies for a reconstructed hydro power plant, incorporating ecological requirements to align with modern sustainability standards.
