Harmonics injected into the voltage and current are caused by power electronic components, lowering the eminence of the power distributed. The use of a Unified Power Flow Controller helps to solve issues in load voltage, source current, and power factor. The UPFC is made up by a dc-link capacitor connecting series and shunt converters, and it is critical to maintain link voltage while delivering less power. As a result, a PV module with a high-gain Switched Clamped Diode Boost (SCDB) converter is introduced, with the GWO algorithm used to track the maximum power. ANN is incorporated to sustain the capacitor DC link voltage. The reference current generation portion achieves proper UPFC control by employing a DDSRF theory for the development of switching sequences of converter connected in series and shunt using a PWM generator. As a result, the source current and load voltage harmonics are reduced, and the power factor is improved. The suggested approach is simulated in MATLAB. [ABSTRACT FROM AUTHOR]

In this situation it becomes mandatory to follow the certain procedures strictly in the commercial Places where gathering of people will be more. To implement this procedure, we required a cost effective, fully automated system which could monitor and control the entry of people as per the directions of the government. The proposed system will screen the entry of people based on their body temperature and the door will be opened only if their body temperature is normal after authorizing their phone number and sanitizing their hands. System is always particular about the social distancing within the premises, hence as per area of premises threshold count of people will be fixed and monitored. As the system hold a complete database of the people visiting the place it will be a fruit for all kinds of commercial and public places. To monitor and control the entry of people in this pandemic situation the database in the cloud will be helpful in tracing the people who have already visited the place if it is required.
