Optimization of robust aiming strategies in solar tower power plants

Abstract

In solar tower power plants aiming strategies are used to distribute the heat flux on the receiver surface. An optimal strategy maximizes the mass flow while avoiding thermal overloading to prevent the risk of damage to receiver components. This problem has been modeled as an integer program (IP) to provide deterministic solutions. To consider disturbances caused by the tracking error, the aiming strategy is extended to ensure a robust solution.
