Data-driven modelling for demand response from large consumer energy assets
Demand response (DR) is one of the integral mechanisms of today’s smart grids. It enables
consumer energy assets such as flexible loads, standby generators and storage systems to
add value to the grid by providing cost-effective flexibility. With increasing renewable
generation and impending electric vehicle deployment, there is a critical need for large
volumes of reliable and responsive flexibility through DR. This poses a new challenge for the
electricity sector.
Smart grid development has resulted in the availability of large amounts of data from
different physical segments of the grid such as generation, transmission, distribution and
consumption. For instance, smart meter data carrying valuable information is increasingly
available from the consumers. Parallel to this, the domain of data analytics and machine
learning (ML) is making immense progress. Data-driven modelling based on ML algorithms
offers new opportunities to utilise the smart grid data and address the DR challenge.
The thesis demonstrates the use of data-driven models for enhancing DR from large
consumers such as commercial and industrial (C&I) buildings. A reliable, computationally
efficient, cost-effective and deployable data-driven model is developed for large consumer
building load estimation. The selection of data pre-processing and model development
methods are guided by these design criteria. Based on this model, DR operational tasks such
as capacity scheduling, performance evaluation and reliable operation are demonstrated for
consumer energy assets such as flexible loads, standby generators and storage systems. Case
studies are designed based on the frameworks of ongoing DR programs in different
electricity markets. In these contexts, data-driven modelling shows substantial improvement
over the conventional models and promises more automation in DR operations. The thesis
also conceptualises an emissions-based DR program based on emissions intensity data and
consumer load flexibility to demonstrate the use of smart grid data in encouraging
renewable energy consumption.
Going forward, the thesis advocates data-informed thinking for utilising smart grid data
towards solving problems faced by the electricity sector
Hotspots of solar potential in India
Solar hotspots are the regions characterized by an exceptional solar power potential suitable for decentralized commercial exploitation of energy. Identification of solar hotspots in a vast geographical expanse with dense habitations helps to meet escalating power demand in a decentralized, efficient and sustainable manner. This communication focuses on the assessment of resource potential with variability in India derived from high resolution satellite derived insolation data. Data analysis reveals that nearly 58% of the geographical area potentially represent the solar hotspots in the country with more than 5 kWh/m(2)/day of annual average Global insolation. A techno-economic analysis of the solar power technologies and a prospective minimal utilization of the land available within these solar hotspots demonstrate their immense power generation as well as emission reduction potential. The study evaluates the progress made in solar power generation in the country especially with the inception of an ambitious National Solar Mission (NSM) also termed as `Solar India'. The organizational aspects of solar power generation with focus on existing policy elements are also addressed so as to probe the actual potential of the identified solar hotspots in meeting the NSM targets and beyond.
