Transmission and Grid Planning

The Government of India, through its Jawaharlal Nehru National Solar Mission (JNNSM), Modified Special Incentive Package Scheme (MSIPS), National Manufacturing Policy (NMP) and Make in India, has announced several measures and incentives favouring renewable manufacturers. The National Wind Mission and the Renewable Energy Law also include a variety of measures that would benefit domestic manufacturers. This report comprehensively examines the manufacturing supply chain of different components used in Renewable Energy (RE) systems, especially wind and solar technology, in India.

Two analytical formulations that describe the fluid interactions of slag with the porous refractory linings of gasification reactors have been derived. The first formulation considers the infiltration velocity of molten slag into the porous microstructure of the refractory material that possesses an inherent temperature gradient in the direction of infiltration. Capillary pressures are assumed to be the primary driving force for the infiltration.

Recently a simple explicit model was introduced to represent theJ–Vcharacteristics of an illuminated solar cell with parasitic resistances and bias dependent photocurrent asj=(1−vm)/(1+αv), here the normalized voltage,vand normalized current densityjcan be represented asv=V/V

The power curve of a wind turbine grows exponentially as a function of wind-velocity if the measured wind-velocity varies between the cut-in velocity and the rated velocity. In this study, we propose an empirical, two-parameter explicit model of the power curve for a wind turbine. The model generalizes different turbine power curves and provides an easy estimate to compare various turbine characteristics.

The growth of RTPV has been sluggish compared to ground-mounted installations. This study analyses the techno-economics of RTPV in different states with their respective net-metering (NM)/gross-metering (GM) regulations and state policies to assess the financial performance of RTPV systems. States having abundant amount of solar potential such as Karnataka, Gujarat, Rajasthan, Maharashtra and Tamil Nadu are considered. The results of this analysis show that there is a lack of favourable consumer-end economics indicated by equity Internal Rate of Return (IRR) and payback period findings.

Closed Loop Brayton cycle power plants using supercritical carbon dioxide (sCO2) have drawn the attention of many researchers in recent times. In this power plant (using heat source from either solar or nuclear),one of the main challenges is the design of the prime mover, namely the turbine. Radial Inflow Turbine (RIT) is found to be a suitable candidate as it has many advantages over Axial Flow TurbinesTechnologies used for the design of RIT for air Brayton cycle are well established.

Sustainable economic development necessitates a careful design of the energy infrastructure.
