Wind And Solar Hybrid Power Generation Grid-connected Technology Research Using Adaptive Fuzzy Logic Control

In today's society,with the exploitation and using of large quantities of fossil fuels such as oil and natural gas,many environmental problems are slowly emerging,such as greenhouse effect,global warming,acid rain,smog,etc.,these environmental pollution seriously affect people's health,life and work.It is the emphasis on resources and the environment that many countries around the world are beginning to study renewable energy such as solar energy and wind energy,The problem of grid connection for clean new energy has also become a hot topic in today's society.In this paper,using the series hybrid active power filter(SHAPF),comparing the power quality improvement techniques of traditional PI control,adaptive fuzzy logic control and fuzzy PI adaptive control,Among them,the advantages of adaptive fuzzy control are reflected.The series hybrid active power filter injection voltage can compensate for the grid voltage imbalance.Harmonics Under balanced non-sinusoidal power supply conditions,current at the point of common coupling reduces total harmonic distortion(THD)below the recommended value,in accordance with IEEE Standard 519-1992.The system utilizes a renewable energy source with an energy storage module to meet the DC-link voltage requirements for connection to a series hybrid active power filter.For the production of the required compensation voltage,the system realizes the DC-link voltage control through the instantaneous reactive power theory based on traditional PI control,adaptive fuzzy logic control and fuzzy PI adaptive control,and performs simulation comparison.Series hybrid active power filters are capable of generating and maintaining the required power to meet load requirements and compensate for short or long voltage interruptions.Through simulation and experimentation,the performance of the proposed grid-integrated three-phase four-wire series hybrid system is confirmed.
