Abstract

The operation of a Wind Energy Conversion System (WECS) is susceptible to the particular circumstances that are present. Consequently, the capacity of a Wind Energy Conversion System (WECS) to deliver a consistent power supply is put to the test in order to satisfy the demand. To guarantee consistent satisfaction of capacity demands, it is essential to possess the appropriate storage device. The volume department is powered by a hybrid wind-battery system, which is incredibly efficient. With the required controls in place, the burden is linked to the WECS to prevent random fluctuations in wind speed.In order to optimize the operational effectiveness of the electrical system and guarantee the well-being of users, the combined design's control logic integrates Maximum Power Point Tracking (MPPT) to govern the inclination of the wind turbine and ascertain the battery bank's charge. In order to guarantee the secure charging of the battery bank, it is the duty of the charge processor to restrict the utmost allowable electricity consumption. Additionally, it evaluates whether the discharge current of the battery remains at or below a threshold of onetenth of its capacity. By means of control mechanisms that are tailored to the process at hand, the buck converter is safeguarded against excessive current. Nevertheless, hypothetical scenarios may arise in which the power supplied to the Maximum Power Point Tracking (MPPT) system surpasses the battery's and application's combined power demands. The pitch angle can be modified through adjustments to the pitch action during power divergence. By incorporating this modification, the output power of the wind turbine can be modified to correspond with the aggregate demand. Furthermore, it possesses the ability to modify WT freedom, and the pitch control logic averts an overvoltage situation caused by the rectifier voltage.
