Patent number: 11961028Abstract: Energy consumption modelling requires to consider various factors affecting the energy consumption in buildings, to be able to effectively forecast future consumption. Even though some of the state of the art deep learning based approaches are able to address these requirements to some extent, they are computationally heavy. The disclosure herein generally relates to energy forecasting, and, more particularly, to a method and system for graph signal processing (GSP) based energy modelling and forecasting. The system monitors and collects information on energy consumption in a building and values of associated energy consumption parameters. This input data is further processed using GSP to generate a building energy consumption model, from which a smooth signal is obtained by applying total variation minimization. The system further performs forecasting using the smooth signal.Type: GrantFiled: January 27, 2022Date of Patent: April 16, 2024Assignee: Tata Consultancy Limited ServicesInventors: Naveen Kumar Thokala, Spoorthy Paresh, Vishnu Brindavanam, Mariswamy Girish Chandra

Publication number: 20230307907Abstract: This disclosure relates generally to methods and systems for determining the power load disaggregation profile of a building. Most of the conventional techniques are algorithmic centric, specific to certain scenarios and does not employ the low-sampling rate data due to the complexity involved. Present disclosure determines the power load disaggregation profile of the building using the low-sampling rate power consumption data accurately. According to the present disclosure, firstly, the background power loads are detected and removed from the low-sampled data samples. Next, a robust event detection mechanism is employed to detect the events when the change in the power consumption occurred, and such events are paired using the iterative pairing technique. Further, a set of event clusters are formed using the density-based clustering technique and lastly, each of the set of event clusters are classified with each appliance type using a rule-based classification technique.Type: ApplicationFiled: February 28, 2023Publication date: September 28, 2023Applicant: Tata Consultancy Services LimitedInventors: NAVEEN KUMAR THOKALA, SPOORTHY PARESH, JOSE IGNACIO MATEOS ALBIACH, ARUP KUMAR DAS, MARISWAMY GIRISH CHANDRA

Publication number: 20220327263Abstract: Power consumption forecasting plays a key role in the efficient operation of a building energy management system to assess energy demands of building, and at the same time, help electrical utilities in planning their supply operations. However, no state-of-the-arts are available for forecasting medium-term or long-term power consumption of the buildings. This disclosure relates to a method and system for forecasting a power consumption of buildings for a scalable forecast horizon. The system is configured to pre-process to deal with outliers/missing values, followed by synchronization of smart meter data with other sensory data. An energy-temperature correlation is calculated to estimate an energy drift using historical power consumptions. Further, in feature derivation stage, additional features necessary for the forecast are derived. The system is to be employed for modeling the building load consumption that depends on the time horizon of forecasting and the granularity of the data.Type: ApplicationFiled: March 2, 2022Publication date: October 13, 2022Applicant: Tata Consultancy Services LimitedInventors: NAVEEN KUMAR THOKALA, VISHNU BRINDAVANAM, SPOORTHY PARESH, MARISWAMY GIRISH CHANDRA

Publication number: 20220284237Abstract: Load disaggregation is useful for both the consumers and producers of energy. The present-day supervised learning models for load disaggregation necessitate the learning of models for every appliance load of interest, which incurs high computational costs. Embodiments of the present disclosure implement a Restricted Boltzmann Machine (RBM) based source-separation model with application to load disaggregation of appliances of interest. Representations of appliance of interest are learnt, between the power aggregate data and the appliance signatures, to output the mapping of data representations on the appliance signatures, for load disaggregation. Discriminative ability for each load/appliance of interest is achieved by adding the free energies of softmax layers of the RBM on other loads/appliance, as a discriminating gradient to the approximate gradients obtained on the load under consideration.Type: ApplicationFiled: November 2, 2021Publication date: September 8, 2022Applicant: Tata Consultancy Services LimitedInventors: Spoorthy Paresh, Naveen Thokala, Vishnu Brindavanam, Mariswamy Girish Chandra

Publication number: 20220269961Abstract: Quantum Information Processing (QIP) with the availability of Noisy Intermediate-Scale Quantum (NISQ) device(s) are available to work on quantum algorithms. Different problems, which are hard to solve by classical computation, but can be sped up (significantly in some cases) are also being populated.
