A Solar and Wind: Hybrid Energy System Connected to the Grid Reduces Voltage Fluctuation and Improve Reliability
A practical energy management method for a small-scale hybrid wind-solar-battery power system is proposed in this research. To evaluate the performance of a hybrid micro grid, dc-dc converter and controllers were built together with wind and solar power conversion and energy storage technologies. The hybrid power system is configured to run at unity power factor, and the Maximum Power Point Tracking (MPPT) methodology is used to control the output voltage as the weather shifts. An energy management system maintains the power balance for fluctuations in renewable energy sources power generation as well as load demand fluctuations. However, this proposed system improved reliability; reduce voltage fluctuations due to various irradiations and wind speed combined with the main grid. The battery with a DC-DC converter is incorporated into the main power system by a 3– - inverter and also the battery is used to store the energy in normal condition and deliver the energy when not available from the sources.
