Performance improvement of a hybrid energy system feeding an isolated load

Abstract

This article concerns with enhancing the dynamics of a hybrid wind/PV/battery system feeding an isolated load. The complete system components are firstly modeled and described in detail. The paper contribution is presented through designing an efficient control topology for managing the dynamics of the wind-driven generator and comparing its performance with one of the existent control algorithms to visualize its advantages. The study also adopts a power management procedure for achieving the optimal power flow in the system. An effective control procedure is also utilized to control the battery performance. The performance of PV system is optimally managed to maintain the maximum power extraction. The obtained results confirm the advantages of the designed controller used with the wind generation system in comparison with the existent control approach. It also approves the validity of the power management procedure in stabilizing the power transfer and achieving an optimal exploitation of wind and solar energies.
