M'zoughi, Fares, Bouallègue, Soufiene, Ayadi, Mounir, Garrido, Aitor J., Garrido, Izaskun.  2018.  Harmony search algorithm-based airflow control of an oscillating water column-based wave generation power plants. 2018 International Conference on Advanced Systems and Electric Technologies (IC\_ASET). :249—254.

The NEREIDA wave generation power plant installed in Mutriku, Spain is a multiple Oscillating Water Column (OWC) plant. The power takeoff consists of a Wells turbine coupled to a Doubly Fed Induction Generator (DFIG). The stalling behavior present in the Wells turbine limits the generated power. This paper presents the modeling and a Harmony Search Algorithm-based airflow control of the OWC. The Harmony Search Algorithm (HSA) is proposed to help overcome the limitations of a traditionally tuned PID. An investigation between HSA-tuned controller and the traditionally tuned controller has been performed. Results of the controlled and uncontrolled plant prove the effectiveness of the airflow control and the superiority of the HSA-tuned controller.
