Incorporating Appliance Usage Patterns for Non-Intrusive Load Monitoring and Load Forecasting
TL;DR: A residential power consumption forecasting mechanism, which can predict the total active power demand of an aggregated set of houses, 5 min ahead of real time, was successfully formulated and implemented utilizing the proposed AUP based technique.
Journal ArticleDOI
Residential Appliance Identification Based on Spectral Information of Low Frequency Smart Meter Measurements
Chinthaka Dinesh,Buddhika Nettasinghe,Roshan Godaliyadda,M. P. B. Ekanayake,Janaka Ekanayake,Janaka Wijayakulasooriya +5 more
TL;DR: The presented results demonstrate the ability of the proposed NILM method to accurately identify and disaggregate individual energy contributions of turned-on appliance combinations in real households.
Journal ArticleDOI
Non-intrusive load monitoring under residential solar power influx
Chinthaka Dinesh,Chinthaka Dinesh,Shirantha Welikala,Yasitha Warahena Liyanage,M. P. B. Ekanayake,Roshan Godaliyadda,Janaka Ekanayake,Janaka Ekanayake +7 more
TL;DR: In this article, the authors proposed a novel non-intrusive load monitoring (NILM) method for a consumer premises with a residentially installed solar plant, which simultaneously identifies the amount of solar power influx as well as the turned ON appliances, their operating modes, and power consumption levels.
Journal ArticleDOI
Implementation of a robust real-time non-intrusive load monitoring solution
Shirantha Welikala,Shirantha Welikala,Neelanga Thelasingha,Muhammed Akram,Parakrama Ekanayake,Roshan Godaliyadda,Janaka Ekanayake,Janaka Ekanayake +7 more
TL;DR: The proposed RT-NILM algorithm was implemented to maintain high accuracy levels even under severe supply voltage fluctuations, and a fast deconvolution based technique was introduced for the disaggregation of individual power levels of active appliances in an computationally efficient manner.
Journal ArticleDOI
Generalized approach to assess and characterise the impact of solar PV on LV networks
Dilini Almeida,Dilini Almeida,Sathsara Madumali Abeysinghe Herath Mudiyanselage,M. P. B. Ekanayake,Roshan Godaliyadda,Janaka Ekanayake,Janaka Ekanayake,Janaka Ekanayake,Jagadeesh Pasupuleti +8 more
TL;DR: A methodology is proposed that can generate a multitude of network topologies that have statistically similar characteristics to a selected cohort of existing networks and facilitates an efficient process for the utility supplier to determine the impact of incorporating new PV connections without the need for extensive studies.
