Transmission and Grid Planning

Solar tower technology has gained considerable momentum over the past decade. In a solar tower plant, a single receiver is used and the power collected by the heliostat field is strongly coupled to the tower height and its location with respect to the field. The literature available focuses largely on the component-level details of the heliostat field, ray-tracing mechanisms, receiver heat transfer analyses, etc.

Analytical expression of the physical parameters of an illuminataed solar cell using explicit J-V model.Simple explicit model was introduced to represent the J–V characteristics of an illuminated solar cell with parasitic resistances

Nuclear power is a crucial source of clean energy for India. In the near-term, India is focusing on thermal reactors using natural and enriched uranium. In the long-term, India is exploring various options to use its large thorium reserves. India’s present nuclear installed capacity is 5680 MW, which contributes to about 3.4% of the annual electricity generation. However, nuclear power is an important source of energy in India’s aspirations for energy security and also in achieving its Intended Nationally Determined Contributions (INDC), of 40% fossil free electricity, by 2030.

A detailed methodology to design the size of solar field for a parabolic trough plant is not explicitly available in open literature, particularly if thermal storage and hybridization are also considered, as most of the papers present a gross overview.

Solar Tower technology has gained considerable momentum over the past decade .Unlike the parabolic trough, Solar Tower has a lot of variants in terms of type of receivers, working fluids, power cycles, size of heliostats, etc .Most of the literature available on this technology does not address in great depths, details of various parameters associated with tower technology.The role and significance of this technology is brought out in the context of the Jawaharlal Nehru National Solar Mission (JNNSM) in order to achieve grid-connected solar power.

A novel approach to determine the non-dimensional heliostat field boundary for solar tower plants.Solar tower technology has gained considerable momentum over the past decade. In a solar tower plant, the power collected by the heliostat field is strongly coupled to the height of the tower and its location with respect to the field. This paper provides a methodology to fix the boundary of the field (non-dimensionalised with respect to the tower height). 

This Policy Brief speaks about domestic manufacturing of polysilicon in India, given the ambitious solar targets. It will require two main policy incentives to make it competitive with international prices: low interest finance (6%) and cheaper electricity.

The policy note examines the existing status of Waste Heat Recovery (WHR) technology in Karnataka and potential uptake in near future. As the fifth most industrialized Indian state, Karnataka's cement, iron and steel sectors consume 28% of the state's total power (as of 2016) and is expected to be in the same range by 2030 as well.

The study aims to develop a methodology to carry out a technical analysis of a solar tower (ST) technology. The proposed rational approach determines the optimum solar field and the associated tower height for an ST using an external cylindrical receiver, using molten salt as both HTF and storage medium operating with steam Rankine power cycle.

Rooftop photovoltaic (RTPV) systems are intended to contribute 40 GW of India's 100 GW solar target. While the uptake of utility-scale solar PV systems is progressing at a steady pace, their RTPV counterparts are witnessing a slow uptake. The sluggish growth can be attributed to a lack of economies of scale, absence of accurate potential assessment, and complexity in procedures.
