PERFORMANCE PARAMETERS, OPTIMIZATION, AND RECOMMENDATION IN LARGE SCALE ON-GRID SPV POWER PLANT, ODISHA, INDIA

Abstract

Traditional energy from coal, fossil fuel, and hydro power plants are environmental, and beyond human
replenishment need to be replaced by renewable sources like solar irradiation, aeolian, tidal, or geothermal. The
copious solar power plant (SPP) is the best substitute of ecofriendly energy source is the rank-1 choice for
developing country, India. Till June 2020, the Solar power plant installed capacity was 36 GW in India targeted
to augment to 100GW by FY-2022.
This present research covers few performance parameters of a SPP and its PR (Performance Ratio), CUF
(Cumulative Utilization Factors) contributed by such a unit of one MW at Bhusandpur in Khordha district of
Odisha installed during 2010 and is still in operation. The yield of the SPP is integrated with the on-grid of the
Khurdha electric power distribution system. To study the performance of the SPP depends upon constraints like
the irradiation, temperature, and climate, design parameters, PR, existing vegetation, regular maintenance, and
climate to be considered at design stage. The longevity of the SPP is considered for 25 years. The SPP
performance measured based on the values of PR or CUF of the plant for the life of span of energy generation.
Present research covers and suggest recommendations for better performance of the one MW SPP Project. To
improve the performance of SPP, site survey was conducted and performance data for 2020 is collected for
analysis,
The present paper is aimed at the performance evaluation and recommendation for improvement of performance
in an existing 1 MW on-grid solar power plant at Khurdha, Odisha, established since 2010. The lowest and
highest power generation has been found to be in the month of August and May about 97,500 kWh and 1,52,600
kWh respectively. The performance evaluation including performance ratio, capacity utilization factor and
payback period of the plant has been carried out, that will support in efficient designing and development of new
grid interactive systems in future.
