Hybrid diesel-wind system with battery storage operating in standalone mode: Control and energy management - Experimental investigation

- Standalone windgenerator -diesel-batteries hybrid system supervision.
- Implementation of an experimental manager.
- A diesel engine ensures balance between the generated and the requested powers.
- Realization of an electrical load simulator of a typical house.

In this work, an experimental Hybrid diesel-wind system with battery storage operating in standalone mode, is presented. The system is comprised of a small scale wind turbine based on 1 kW PMSG, storage batteries, a charge controller, an inverter, a diesel generator, a weather station, a data logger, an electrical load prototype realized and developed such as to simulate a typical house consumption, the controller and the current and voltage sensor.The main task of the proposed scheme was confirmed under three considered scenarios corresponding respectively to low wind speed and high state of charge of batteries, high wind speed and moderate state of charge of batteries and moderate wind speed and low state of charge of batteries while the extensive measurement results demonstrate the system ability to run as expected each of these modes. On the other hand, the data logger via the realized current and voltage sensor as well as the different software and computer tools used and exploited in the present experimental study allowed the permanent supervision and follow-up of the whole system which enabled also to intervene at any time in order to improve the behavior of the whole system.
