Power Quality Improvement of Electric Grid Connected Wind-Solar Hybrid Energy System using STATCOM

Voltage, current, time or frequency is the nonstandard occurrence due to a power quality problem that manifested in a failure or uncontrollable or bug locked end user equipment’s. The service interruptions developed by such the nonstandard occurrences may affect the utility distribution networks, critical commercial operations and the industrial sensitive loads, which can lead to the cost significant financial losses. In this paper, the issue of this power quality has taken on new dimensions to achieve the distributed and dispersed generation by restructuring the power systems with a modified shifting trend. Usually in the distribution center, the electric grids affect the power quality when the wind power is injected on it. International Electro-technical Commission standard, IEC-61400 provides the guidelines to measure the power quality through the performance of wind turbine. Active power, reactive power, harmonics, electrical switching behaviour, variation of voltage, and flicker are the power quality measurements and are obtained from the grid systems of wind turbine based on national and international guidelines. This paper proposes a new procedure to install the wind turbine with the electric grid. The static synchronous compensator is connected in a common coupling point to migrate the power quality issue of a conventional technique. The proposed wind energy generation system is simulated in MATLAB-Simulink with both linear and nonlinear loads to observe the power quality improvement.
