India aims to meet its growing power demands through the expansion of its renewable energy capacity. This warrants a strong transmission infrastructure to integrate and evacuate renewable energy, as a transmission network acts as the backbone of power systems to transfer power from generation stations to load centres. As the country works towards this mission, a thorough transmission network analysis is needed to design a power evacuation scheme and assess technical feasibility. CSTEP supports transmission utilities to strengthen their transmission infrastructure and integrate a higher share of renewable energy to provide a reliable supply.
Analytical derivation of equivalent functional form of explicit J–V model of an illuminated solar cell from physics based implicit model
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
An empirical model of power curve of a wind turbine
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.
Comparative Techno-Economic Analysis of Rooftop PV (RTPV) Systems in Various States in India
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.
Mean Line Design of Radial Inflow Turbine for sCO2 Power System
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.
Machine Level Energy Efficiency Analysis in Discrete Manufacturing for a Sustainable Energy Infrastructure
Sustainable economic development necessitates a careful design of the energy infrastructure.
Utilisation of Rice Residues for Decentralised Electricity Generation in Ghana: An Economic Analysis
This publication enlighten the reader about how electricity can be produced using the rice husk at Ghana.
Feasibility Analysis for c-Si PV Manufacturing in India
India has set a target of deploying 100 GW solar power by 2022. Solar installations in the country primarily use Photovoltaic (PV) technology. It is estimated that 339-395 GW of solar PV will be deployed by 2040. At present, the domestic cell and module manufacturing capacities stand at approximately 3.2 GW and 8.4 GW, respectively. However, the existing manufacturing capacities are underutilised.
Re-assessment of India’s On-shore Wind Power Potential
Till recently, the on-shore wind power potential in India was officially estimated to be 102 GW at a hub height of 80 m. About 26 GW of this potential has been installed in the country. However, there are multiple independent reassessment studies in the public domain that estimate the potential to be much higher. This is due to variations in assumptions and methodologies used.
Nuclear Waste Management
This report is written to enlighten the reader about the quantity of radioactive waste generated and how it is being managed and what are the courses of action required for effective containment and disposal.
