Publication number: 20230419211Abstract: This disclosure relates generally to optimal intraday scheduling of aggregated Distributed Energy Resources (DERs). Owing to their stochastic nature, DERs aggregators are more suited to participate in intraday electricity markets. The current works on DER aggregators trading in intraday markets do not satisfactorily model the different aspects. The disclosure is an optimal trading strategy for aggregators managing heterogeneous DERs to participate in intraday markets. The intraday market is modelled using a joint price-volume dynamics distribution and an optimal bidding strategy is disclosed for the trades/bids placed earlier to be corrected based on the revised forecasts of demand and generation while allowing for energy exchanges within the DER pool. Further the optimal bidding strategy of aggregators in an intraday market is a MINLP problem, which is solved by converting the complex non-linearities in the problem into a coupled MILP—simple maximization set-up, which is then solved in an iterative fashion.Type: ApplicationFiled: May 24, 2023Publication date: December 28, 2023Applicant: Tata Consultancy Services LimitedInventors: VISHNU PADMAKUMAR MENON, YOGESH KUMAR BICHPURIYA, VENKATESH SARANGAN, SMITA LOKHANDE, ASHUTOSH PRAJAPATI, NARAYANAN RAJAGOPAL, NIDHISHA MAHILONG

Publication number: 20230410201Abstract: Owing to their stochastic nature, Distributed Energy Resources (DERs) are more suited to participate in short-term or intraday electricity markets. However, it is very difficult for an asset owner to manage their operation when interacting with markets and create operation schedules. Present disclosure provides systems and methods that for the trades/bids placed earlier to be corrected based on the revised forecasts of demand and generation in the DER pool. The system models an optimal bidding problem of aggregators in an intraday market as a mixed-integer non-linear programming (MINLP) problem. The MINLP problem is converted to an NLP problem by an optimization model and integer variables are relaxed to solve the NLP problem and obtain (i) an optimal intraday operating schedule for one or more DERs, and (ii) an intraday bid associated with the DERs for a plurality of delivery slots to be traded in an intraday market.Type: ApplicationFiled: May 24, 2023Publication date: December 21, 2023Applicant: Tata Consultancy Services LimitedInventors: SMITA SANJAY LOKHANDE, NIDHISHA MAHILONG, ASHUTOSH PRAJAPATI, YOGESH KUMAR BICHPURIYA, VISHNU PADMAKUMAR MENON, VENKATESH SARANGAN, NARAYANAN RAJAGOPAL

Patent number: 11623527Abstract: Vehicle-to-Grid (V2G) technologies are being adopted to reduce peak demand and to take over as energy sources during grid instability. It is necessary to estimate attributes of electric vehicle trips and residual battery charge in order to correctly predict spatio-temporal availability of energy from EVs to form a micro grid. However, it may not be feasible to get the required attributes for all vehicles in a city-scale traffic scenario. Embodiments of the present disclosure and system address the problem of accurately estimating the local energy reserve that is available from parked EVs during a given time of the day. In addition, the system also determines which neighborhoods have the potential to form micro grids using the parked EVs during a given time period. This will help grid operator(s) to plan and design smart grids which can create EV-powered micro grids in neighborhoods during periods of peak demand or during disruptions.Type: GrantFiled: June 27, 2018Date of Patent: April 11, 2023Assignee: TATA CONSULTANCY SERVICES LIMITEDInventors: Arvind Ramanujam, Pandeeswari Indumathi Sankaranarayanan, Arunchandar Vasan, Rajesh Jayaprakash, Venkatesh Sarangan, Anand Sivasubramaniam

Patent number: 11609156Abstract: Traditionally, benchmarking of asset performance involves comparing actual performance with ideal values that correspond to test conditions which may not be realized in practice leading to inappropriate ranking of the assets. Systems and methods of the present disclosure use condition-aware reference curves for estimating the maximum possible operating efficiencies (under specific operating conditions) instead of the theoretical maximum efficiencies. The reference curves are received from the manufacturer or obtained from on-site test results. Benchmarking is then performed based on two dimensions, viz., an inter-asset metric and an intra-asset metric that are analogous to the first law and second law of thermodynamics respectively. The two-dimensional benchmarking then helps in identifying inefficient assets that may be analyzed further for finding the root cause.Type: GrantFiled: September 20, 2019Date of Patent: March 21, 2023Assignee: TATA CONSULTANCY SERVICES LIMITEDInventors: Srinarayana Nagarathinam, Venkata Ramakrishna P, Arunchandar Vasan, Venkatesh Sarangan, Anand Sivasubramaniam

Publication number: 20230063075Abstract: This disclosure relates generally to method and system to generate pricing for charging electric vehicles. With Electric vehicles becoming more mainstream, public chargers may not be able to match demand supply without extensive deployments. The present disclosure dynamically generates pricing policies to maximize aggregator revenue based on a stochastic model constraints and user behavioral models. The system involves three primary stake holders comprising a demand side having EV users requesting efficient charging at lowest possible price, a supply side which includes a public or private EVSE operators, and an EV charging aggregator which acts as intermediator between the demand side and the supply side. The EV charging aggregator having an RL agent receives user requests to generate pricing based on a tentative demand pool, an actual demand pool, and a service pool. The reward to the RL agent is the total revenue obtained in that timestep of the control action.Type: ApplicationFiled: July 1, 2022Publication date: March 2, 2023Applicant: Tata Consultancy Services LimitedInventors: PRASANT KUMAR MISRA, AJAY NARAYANAN, AAKASH KRISHNA GURUVAYUR SASIKUMAR, ARUNCHANDAR VASAN, VENKATESH SARANGAN

Patent number: 11538100Abstract: Sum of bid quantities (across price bands) placed by generators in energy markets have been observed to be either constant OR varying over a few finite values. Several researches have used simulated data to investigate desired aspect. However, these approaches have not been accurate in prediction. Embodiments of the present disclosure identified two sets of generators which needed specialized methods for regression (i) generators whose total bid quantity (TBQ) was constant (ii) generators whose total bid quantity varied over a few finite values only. In first category, present disclosure used a softmax output based ANN regressor to capture constant total bid quantity nature of targets and a loss function while training to capture error most meaningfully. For second category, system predicts total bid quantity (TBQ) of a generator and then predicts to allocate TBQ predicted across the various price bands which is accomplished by the softmax regression for constant TBQs.Type: GrantFiled: March 24, 2020Date of Patent: December 27, 2022Assignee: TATA CONSULTANCY SERVICES LIMITEDInventors: Avinash Achar, Abhay Pratap Singh, Venkatesh Sarangan, Akshaya Natarajan, Easwara Subramanian, Sanjay Purushottam Bhat, Yogesh Bichpuriya

Patent number: 11301941Abstract: Electrical utilities offer incentives to customers to reduce consumption during periods of demand-supply mismatch. A building's participation in demand response (DR) depends both on its ability (due to building constraints), and its willingness (a function of incentive) to reduce electricity. Customers prefer a large incentive whereas a utility would want to minimize the revenue outflow to achieve a target reduction. Systems and methods of the present disclosure identify optimal incentive from the utility's perspective reflecting this trade-off. A model is built to estimate the demand response potential (DRP) of a building for a given incentive offered by the utility. The models for individual buildings are used to characterize the behavior of an ensemble of buildings. The utility may then decide optimum incentives that should be offered to achieve a target DR, using the associated DRP.Type: GrantFiled: November 6, 2017Date of Patent: April 12, 2022Assignee: Tata Consultancy Services LimitedInventors: Kundan Kandhway, Arunchandar Vasan, Srinarayana Nagarathinam, Venkatesh Sarangan, Anand Sivasubramaniam
