Location: Hyderabad, India

Organization: Nagarjuna Construction Company, India

Position: Electrical Engineer

  1. Background

[CE 1.2] For isolated loads or household purposes, the standalone-PV systems are generally used. The power demand increment in the utility end with lesser fluctuations and harmonics are the major issues. The energy conventional sources have the probability to last for a limited time but energy renewable sources such as solar energy are eco-friendly and infinite. With the power electronics devices enhanced efficiency, the utilization of solar energy can be done by providing power to the consumers. The solar energy only flaw is that the set-up needed is expensive.

[CE 1.3] The main aim was the MPPT control implementation of the standalone-PV system to supply power with battery to the loads. The battery worked as an energy storage element and it was utilized as a power source when PV was insufficient for the same. I executed the system which comprised of PV panel, a boost converter circuit, and a battery. I implemented the hardware and software design with the boost converter for tracking the maximum power point of the PV panel from duty cycle controlling. It worked as the boost converter gate pulse and the battery function was for maintaining a constant dc-link voltage.

[CE 1.6] Core responsibilities in the project were:

  • I did snubber circuit consideration which was required when an inductor was present in the design.
  • I did ceramic capacitors utilization mainly for higher frequency spikes removal.
  • I executed the hardware and software design implementation for the boost converter for obtaining the work results using electrical engineering expertise.
  • I carried out three LEDs connection with the microcontroller for noting the output values associated with the design.
  • I utilized the sensor specifically for current sensing from the solar panel which was typically fed to the Arduino analog pin.

Project: Electrical Power System Analysis

Duration: [Date] – [Date]

Location: [location]

Position: Electrical Engineer

  1. Background

[CE 2.2]Electrical power supply disturbances can have serious issues for everyday life as well as for national security. The power outage can typically be started from adverse weather, natural disasters, human errors, the act of war, and other factors. The system vulnerability was defined as threats and hazards sensitivity and was measured from P(Q9(t) >q). It worked as the probability of at least one disturbance with negative societal consequences. It was specifically during the period (0, t). The work aim was based on presenting techniques for quantitative vulnerability analysis of electric power delivery networks for enabling the techniques specifically related to mitigation, response, prevention, and recovery.

[CE 2.3]The project objective was presenting techniques for electric power quantitative vulnerability analysis for enabling the effective prevention, mitigation, response, and recovery strategies. I contributed towards the rational approaches development for resource allocation analysis. It was specifically for assisting policy and decision-makers for the evaluation of strategies and measures for critical infrastructure protection. Numerous concept vulnerability definitions were linked with no general definition. I formalized vulnerability which acted as a theoretical concept and utilized in quantitative analysis for power delivery networks.

[CE 2.6] Assigned responsibilities were:

  • I carried out technical systems traditional risk analysis specifically based on the technical failures.
  • I carried out an existing system analysis which was for checking the status along with the changes executed appropriately in the project.
  • I analyzed the responses which mainly linked to the possible crises responses development.
  • I did three principal methods implementation for the probability estimation occurrence of an event.

Title: Lighting Load Control using GSM

Duration: [Date] – [Date]

Location: [Location]

Position: Electrical Engineer

  1. Background

[CE 3.2]

In a building, Plug and process loads include all plug-in and hardwired loads that are not associated with ventilating, heating, and air-conditioning (HVAC), water heating, lighting, and other major equipment for appropriate building operation. There are process loads including for commercial equipment within a building shell, like vertical transportation or equipment such as industrial washing machines present in hotels. There are building end uses diversity obtained and equipment widely vary with building method, individual preference, and organizational mission.

[CE 3.3]

The work aim was specifically for improving the BAS and EMIS platforms’ integration of PPLs. I set the stage for identifying the synthesis and it included highlighting the areas for DOE appropriate points. I directly connected the DOE’s core research areas and carried out the smart building technology integration with the grid-interactive efficient buildings. I did PPL data integration into EMIS platforms and PPL data interoperability with other building end-use data. I executed the testing and development of the automatic PPL controls.

[CE 3.6] The work duties were:

  • I researched and set recommendations for impactful data collection from building end usage.
  • I researched appropriately for PPL controls algorithms implementation which was linked with the end-use building data specifically for complete building-energy consumptions.
  • I executed the dynamic and automatic load detection capabilities with integration and data management.
