Reactive Power Compensation of Hybrid Renewable Energy System Using P-Q Theory

Electricity is the most preferred form of energy used in all the areas. In the present situation, the global issues are increasing. So an alternative energy source is required for power generation. Renewable energy sources such as photovoltaic, wind energy, and fuel cell in the form of hydrogen gas has more advantages and can be used as an alternative energy source. In order to meet the sustained load demand during varying natural conditions, these sources are integrated to form a hybrid system, and it is used for power generation. Hybrid system designed with conventional methods introduces various power quality issues in the system. P-Q theory is an interesting tool to apply the control of active power filters to analyse three-phase power system in order to detect problems related to harmonics, reactive power. So, in the proposed model, a hybrid system designed with instantaneous reactive power theory set improves the power quality issues. MATLAB/SIMULINK is used as a simulation tool for analysing.
