Power management of an isolated hybrid energy production unit with super-capacitor

The aim of this paper is to propose a power control strategy of an isolated hybrid energy production unit. The proposed (wind / photovoltaic / diesel / super-capacitor) hybrid system is found to be the configuration to ensure a continuous feed of a three-phase load and to secure the storage system. An overall power management strategy is designed to manage power flows between the different energy sources and the storage unit. In this context, we used a control algorithm which describes four operating modes. The obtained simulation results are presented and discussed and the control strategy is validated for different scenarios.
