Power control for decentralized energy production system based on the renewable energies — using battery to compensate the wind/load/PV power fluctuations
Résumé
10kW-diesel generator associated to renewable energy sources including a 10kW wind turbine, 12kW photovoltaic, and 53Ah lithium-battery. These energy production sources are interfaced to micro-grid through three-level power electronics converters where the phase-to-phase RMS voltage is 600V. The variable speed diesel generator is considered as the main energy source which is used to control the DC-bus voltage. The wind turbine and PV system are controlled using the Maximum Power Point Tracking (MPPT) technique with bipolar DC-bus voltage equilibration approach. The battery pack is used to compensate the intermittent power fluctuations from the wind turbine and PV system. The hybrid system control is ensured by the three-level converters (AC/DC, DC/DC, and DC/AC) using energy management based on frequency components allocation approach.
