Stress Reduction of Turbine Units in Hybrid Power Plants: an Operational Perspective

This paper develops an operation strategy for hybrid power production units (turbine integrated with energy storage) participating in the balancing of the power grid. The developed strategy targets the reduction of the mechanical stress of the hybrid’s turbine unit by utilizing the available storage capacity. The problem is addressed using the methods of operations research combined with the receding horizon control approach. The benefits of the operational strategy are demonstrated via numerical simulations.
