    • "IoT and MACHINE LEARNING BASED POWER QUALITY IMPROVEMENT SYSTEM FOR MICRO-GRID" Exemplary aspects of the present disclosure are directed towards the IoT and Machine Learning Based Power Quality Improvement System for Micro-Grid consists of the plurality of Line Monitoring & Control System (LMCS) 101 connected to Central Monitoring & Control System (CMCS) 103 through Communication-Network 102. LMCS 101 is an integration of microcontroller 101a with advanced power-management chip 101b, two pair of three potential-transformers 101d and current-sensors 101c, Circuitry for Circuit-Breaker 10le control, and Capacitor-Banks 101f. LMCS 101 uses the Machine-Learning (ML) algorithm to predict power quality issues and operates respective Capacitor-Banks 101f for mitigating voltage and frequency profiles. All the power data received by CMCS 103 is normalized and fed to relevant ML algorithm to identify and predict, load, line stress and power quality issues and mitigate the problems. Based on mitigation CMCS 103 isolates the section if necessary by operating the concerned Circuit-Breaker 101e or switch on the concerned capacitor-banks. Page 1 *Acquire Current and Voltage magnitudes and respective wave forms through Power IC 101b. Assign time stamping to the acquired values along with LMS Compare waveforms of two sets of currents and voltages of that line and compute the change in currents and voltages Al AV and Power Factor. Using relevant machine learning algorithm, ascertain whether Al and AV values are in limits in comparison them with set values If anomaly is found in Al and AV, then feed the values directly to machine learning algorithm and predict the type of power quality issue alert the CMCS-MAIN and await for the mitigation strategy. Based on mitigation strategy, connect capacitors of the respective capacitor bank. Acquire Al and AV after energies the capacitor banks and fed the values to respective MLA for determining and predicting their safe values. If the PQ issues persisting, then increase the capacitor bank 10 lg values and again Acquire Al and AV If Al is high and persistent after the step 507, then ascertain the type of PQ issues and intimate the CMCS with time stamping & LMCS ID and upload power data and type of PQ issue.
