Analysis of Power Quality Issues due to the Proposed Solar Power Plants in Hambantota
Karunadasa, JP; Ratnasiri, MD (2014)solar power plants, despite their high initial investment, are fast spreading in Asian countries owing to the availability of higher solar radiation throughout the daytime. In Sri Lanka, two grid-connected small-scale solar ... -
A Comparative Evaluation of Existing Mppt Algorithms and Development of a Hybrid Algorithm for Photovoltaic Systems
Kumara, CPTK; Karunadasa, JP (2015)This Research paper is about a comparative evaluation of different existing algorithms for Maximum Power Point Tracking (MPPT) of photovoltaic (PV) systems, and developing of a new hybrid-algorithm. Solar panel is a non ... -
Investigation of the Effects of DC Current at the Point of Common Coupling on the Operation of Distribution Transformers
Herath, HMAI; Karunadasa, JP (2016)Non-linear loads, such as ac and dc motor drives, computers etc. connected to the power distribution network inject a DC current component back to the network. Individual currents from different loads add at the point of ... -
Modelling and Simulation of Power Transformers under a DC Offset Produced by Load Current
Herath, HMAI; Karunadasa, JP (2019) -
Overvoltage Issues Due to Solar Photovoltaic (PV) Integration at Low Voltage (LV) Side
Karunadasa, JP; Dabare, ASN; Disssanyake, DMKC (2019)In Sri Lanka, due to the current power suspense, solar power harnessing intends to increase significantly with the support from the government renewable energy policy. As a result, deployment of Photovoltaic (PV) systems ...
