B. Background
[CE 1.2]
For isolated loads or household purposes, standalone PV systems are generally used. The incremental power demand at the utility end, with lower fluctuations and harmonics, is a major issue. Conventional energy sources have a limited lifespan, but renewable energy sources, such as solar energy, are eco-friendly and renewable.
With the power electronics devices enhanced efficiency, the utilization of solar energy can be done by providing power to the consumers. Solar energy’s only flaw is the cost of the required setup.
[CE 1.3]
The main aim was to implement MPPT control for the standalone PV system to supply power from the 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 for a boost converter to track the maximum power point of the PV panel using duty-cycle control. It worked as the boost converter’s gate pulse, and the battery function maintained a constant DC-link voltage.

Core Responsibilities in the Project were:
- I considered the snubber circuit, which was required when an inductor was present in the design.
- I did ceramic capacitors utilization mainly for higher frequency spikes.
- I implemented the hardware and software design for the boost converter, delivering the results using electrical engineering expertise.
- I connected three LEDs to the microcontroller to record 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 analogue pin.

- Project: Electrical Power System Analysis
- Duration: [Date] – [Date]
- Location: [location]
- Position: Electrical Engineer
B. Background
[CE 2.2]
Electrical power supply disturbances can pose serious problems for everyday life and national security. Adverse weather, natural disasters, human error, acts of war, and other factors can typically cause power outages. The system vulnerability was defined as threat and hazard sensitivity and measured as 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 aimed to present techniques for quantitative vulnerability analysis of electric power delivery networks, enabling targeted mitigation, response, prevention, and recovery.
[CE 2.3]
The project objective was to present techniques for quantitative vulnerability analysis of electric power systems to enable effective prevention, mitigation, response, and recovery strategies. I contributed towards the rational approaches for resource allocation analysis. It was specifically designed to assist policy and decision-makers in evaluating strategies and measures for protecting critical infrastructure.
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 2.4]
Assigned Responsibilities Were:
- I conducted traditional technical systems risk analysis, specifically focused on technical failures.
- I conducted an existing system analysis to assess the status, along with the changes implemented in the project.
- I analyzed the responses, which mainly linked to the possible crisis response development.
- I used three principal methods for estimating the probability of an event occurring.
