The application of power electronics devices (PED) to control non-linear, unbalanced loads leads to power quality (PQ) issues. This work presents a hybrid controller for the self-tuning filter (STF)-based Shunt active power filter (SHAPF), integrated with a wind power generation system (WPGS) and a battery storage system (BS). The SHAPF comprises a three-phase voltage source inverter, coupled via a DC-Link. The proposed neuro-fuzzy inference hybrid controller (NFIHC) utilizes both the properties of Fuzzy Logic (FL) and artificial neural network (ANN) controllers and maintains constant DC-Link voltage. The phase synchronization was generated by a self-tuning filter (STF) for the effective working of SHAPF during unbalanced and distorted supply voltages. In addition, STF also does the work of low-pass filters (LPFs) and HPFs (high-pass filters) for splitting the Fundamental component (FC) and Harmonic component (HC) of the current. The control of SHAPF works on d-q theory with the advantage of eliminating low-pass filters (LPFs) and phase-locked loop (PLL). The prime objective of the projected work is to regulate the DC-Link voltage during wind uncertainties and load variations, and minimize the total harmonic distortion (THD) in the current waveforms, thereby improving the power factor (PF).Test studies with various combinations of balanced\/unbalanced loads, wind velocity variations, and supply voltage were used to evaluate the suggested method\u2019s superior performance. In addition, the comparative analysis was carried out with those of the existing controllers such as conventional proportional-integral (PI), ANN, and FL.<\/jats:p>","DOI":"10.3390\/a15080256","type":"journal-article","created":{"date-parts":[[2022,7,25]],"date-time":"2022-07-25T21:20:59Z","timestamp":1658784059000},"page":"256","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Design of Multi-Objective-Based Artificial Intelligence Controller for Wind\/Battery-Connected Shunt Active Power Filter"],"prefix":"10.3390","volume":"15","author":[{"given":"Srilakshmi","family":"Koganti","sequence":"first","affiliation":[{"name":"Department of Electrical and Electronics Engineering, Sreenidhi Institute of Science and Technology, Hyderabad, Telangana 501301, India"}]},{"given":"Krishna Jyothi","family":"Koganti","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Geethanjali College of Engineering and Technology, Hyderabad, Telangana 501301, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3849-6051","authenticated-orcid":false,"given":"Surender Reddy","family":"Salkuti","sequence":"additional","affiliation":[{"name":"Department of Railroad and Electrical Engineering, Woosong University, Daejeon 34606, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,25]]},"reference":[{"key":"ref_1","unstructured":"Vijayakumar, G., Nitin, G., and Gupta, R.A.
