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.
Quantifying PhotoVoltaic Power Variability Using Lorenz Curve
Short-term variability of utility-scale solar PhotoVoltaic (PV) plant is a significant issue for grid reliability. It is necessary to quantify the solar power variability in order to analyze the power variations on the electricity distribution network. In this paper, a Lorenz curve-based method is described to quantify the variability of power output from a megawatt-scale solar PV plant. The proposed method is used to analyze the power variability of Yelesandra PV power plant located in the state of Karnataka, India.
Correlation Between Central Receiver Size and Solar Field Using Flat Heliostats
In Central Receiver Systems (CRSs), thousands of heliostats track the sunrays and reflect beam radiation on to a receiver surface. The size of the reflected image and the extent of reflection from the heliostats are one of the important criteria that need to be taken into account while designing a receiver, since spillage losses may vary from 2 to 16% of the total losses. The present study aims to determine the size of an external cylindrical receiver, such that the rays reflected from all the heliostats in the field are intercepted.

A Statistical Model for Wind Power on the Basis of Ramp Analysis
Due to stochastic nature of wind distribution, wind power output comes with unscheduled changes called ramp events. In this paper, a semi-analytical approach is considered to analyze the distribution of ramp events. A simple empirical equation is derived based on the probability of wind ramp events considering the stochastic nature of wind power distribution for the Indian state of Karnataka.
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.
Harnessing Solar Energy: Options for India
The overall goal of the off-grid guidelines of the JNNSM is to achieve wider dissemination of solar
technology, and a generous capital subsidy of up to 90% is offered for rural applications Even so,
there are several bottlenecks to large-scale dissemination Primarily, the techno-economics,
financing and institutional mechanisms of several solar applications are not well understood
Therefore, these form a focus of this study In addition, this study looks at the Government of India’s
A Study of Energy Efficiency in the Indian Cement Industry
The objective of this study has been to model the Energy Efficiency (EE) of the Indian cement industry, in the context of the diversity and the challenges in operating conditions, in order to provide analysis and insights for the successful implementation of PAT.
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 the J–V characteristics of an illuminated solar cell with parasitic resistances and bias dependent photocurrent as j = (1 − vm)/(1 + αv), here the normalized voltage, v and normalized current density j can be represented as v = V/Voc and j = J/Jsc respectively, whereVoc is the open circuit voltage and Jsc is the short circuit current density. The model is an equivalent rational function form and useful for design, characterization and calculation of maximum power point voltage.
