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.

In this report, we examine current and proposed IT initiatives being undertaken by HESCOM, and suggest changes in the technology design as well as a roadmap for IT initiatives. The focus is not on technology details but high-level design and integration of these into the business processes and institutional frameworks of the utility. This effort is mindful of and compatible with R-APDRP initiatives, including those by the Empanelled IT Consultants.

This paper aims to inform the tariff setting process for wind resource in Karnataka, so that investments in wind infrastructure can be incentivized taking into consideration resource variations. This work presents a range of levelized tariffs for the on-shore wind potential of the state. The range is a result of the variation in capacity utilization factors estimated for various classes of Wind Power Density (WPD) in the state, for waste and scrub forest land categories, at 80 m and 100 m hub heights.

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.

The study of networks and network science has grown in the last decade, but most network models fail to capture the costs or loss of value of exclusion from the network. Intuitively, as a network grows in size and value, those outside the network face growing disparities. This new direction is relevant too for the design of policy interventions as well as for shifting the scholarly research agenda toward greater focus on inequality and exclusion.

This publication enlighten the reader about how ectricity can be produced using the rice husk at Ghana.Developing countries, especially in Sub-Saharan Africa, face large challenges to achieve universal electrification Using the case of Ghana, this study explores the role that rice residues can play to help developing countries meet their electrification needs In Ghana, Levelised Electricity Costs (LEC) of a grid-connected 5 MWe straw combustion plant ranged between 116 and 130 UScents/kWh, based on region of implementation .Rice straw combustion is a viable grid-connected option in all regi

The J–V equation of a solar cell is implicit and requires iterative calculation to determine the fill factor and the maximum power point. Here an explicit model for J–V characteristic is proposed which is applicable to a large variety of solar cell. This model allows an easy estimation of fill factor from four simple measurements of the bias points corresponding toVoc, Jsc, and any two voltage values lying between 0 and Voc, where Voc is the open circuit voltage and Jsc is the short circuit current density.
