Journal article (peer-reviewed)abstract
- Globally, the demand for energy from renewable sources is growing due to the increasing electricity consumption and the pollution of fossil fuels. The government has framed various policies to facilitate green energy generation, encouraging renewable energy source usage through PV installations in multiple sectors, including educational institutions. The primary objective of this paper is to propose a methodological approach for analysing the performance of the installed PV system on the rooftop of a university building in Tamil Nadu, India. The site selected is favourable for electricity generation from PV systems with an average global solar radiation of 5.82 kWh/m2day. Solar energy changes periodically with annual and daily variations and is not steady due to seasonal changes. The step-by-step performance assessment and the annual performance of the 100-kW solar PV system, which was instituted in 2019, with the forecasted parameters, are presented in this paper. Therefore, the assessment analysis is carried out in four phases: feasibility assessment, Energy yield assessment, Life cycle assessment, and Power quality assessment. To improve the solar PV output and efficiency, considering the solar irradiation, temperature, wind velocity, etc., PV yield is measured to evaluate the PV system's energy metrics. This paper also considers the carbon credits earned, solar power generated in the location, and the payback period. The power quality assessment is carried out in this paper to test the PV plant's compliance with effective grid integration.

Conference paper (peer-reviewed)abstract
- In this paper, a multi-port non-isolated SEPIC converter is analysed for integrating with the renewable energy source and also losses and efficiency are calculated. The proposed converter utilizes a single stage power conversion, thereby providing higher energy efficiency. The proposed structure comprises of a combination of Pulsating Voltage Cells (PVC) and Pulsating Voltage Source Cell (PVSC) on the input side and a Pulsating Voltage Load Cell (PVLC) on the output side. The two topologies involved are Multi Input Single Output (MISO) and Multi Input Multiple Output (MIMO) which are bidirectional. The efficiency of the proposed multi-port converter has been calculated by determining the switching stress of the power electronic switches used. The proposed multi-port SEPIC converter considers the entire system to be a single-stage converter, and promises higher energy efficiency.

Conference paper (peer-reviewed)abstract
- The objective and purpose of this study is to implement a peak shaving algorithm in an islanded microgrid for economic power consumption. The simulation of this study has been created through MATLAB/Simulink. This system works for different peak demands and can easily be manipulated, providing us a dynamic approach to the system for maximum efficiency and maximum power generation for the required demand. Added to this, we have also included grid-tied solar panels which are renewable and eco-friendly. The results from the simulation show us clearly that the peak shaving algorithm gets activated as soon as the supply surpasses the peak demand. When this activation happens, the grid is islanded and it goes into self-generation mode. The current use of the grids is aged and is not able to support the current population from time to time. This paper will prove to be a viable, cost-effective and simple solution for the power stations. The simulation, functioning, observation, inference, advantages and disadvantages have been completely provided in this paper with the help of reference papers which have been mentioned towards the end.

Journal article (peer-reviewed)abstract
- This study investigates the long-term performance of a 52-kW on-grid solar PV plant in the Mechanical ‘C’ block, SRM Institute of Science and Technology (SRMIST). This article delivers a simple approach that would act as a pivot for PV system assessment. Therefore, methodologies like Energy yield analysis, Energy distribution, and Life cycle costing are implemented. This empowers the methods to facilitate pre-auditing, energy conservation, and economic analysis. The performance ratio and a capacity factor of the 52-kW PV plant in 2020 are determined as 60% and 12.8%, respectively. The study offers that the plant has a less simple payback period and energy pack time for 2020. From this study, the issues identified in the plant are highlighted with the solution. It also paves the way for the researchers to suggest the solutions for the underutilisation of the plant, especially in the situations like fault occurrence, pandemic conditions, etc.
