A type-1 fuzzy logic algorithm to manage the flow of energy in a stand-alone PV/wind/battery hybrid system

The significant increase in the prices of conventional energy sources and the public awareness of the need to reduce global warming have encouraged many countries to develop new systems based on renewable energies. Combining renewable energy sources with storage units to form a multi source system can provide a more economic, and reliable supply of electricity in all load demand conditions compared to a single-use of such systems. The energy balance between production and consumption should be carefully conducted while choosing the storage method to ensure the availability of power on demand and improve the dynamic behavior of the hybrid system. This paper presents a study of a HRES composed of Photovoltaic (PV) solar panels and a wind turbine as primary energy sources and batteries as storage units and proposes a computer algorithm based on type-1 fuzzy logic to control the energy between production and consumption and ensure the availability of power on demand.
