Model-Free Wind Farm Power Production Optimization using Multi-Resolution Optimized Relative Step Size Random Search

Abstract

This study investigates the performance of Multi-Resolution Optimize Relative Step Size Random Search (MR-ORSSRS) based method in maximizing the total power production of wind farms under circumstances of varying wind directions, turbine failures and non-static wind conditions. With the Horns Rev Wind Farm layout as the basis, the proposed method is compared against the benchmarked Multi-Resolution Stochastic Perturbation Simultaneous Approximation (MR-SPSA). Multi-Resolution (MR) function is further integrated alongside MR-ORSSRS in view of improving the method’s convergence speed. Simulation results hereby show that MR-ORSSRS based method performs MR-SPSA in terms of convergence speed, accuracy and robustness in generating maximum power, even in the cases of deviating wind speeds, turbine failures and varying wind directions.
