Thin films of C70 were grown on double side polished silicon substrate by resistive heating of C70 powder. These films were irradiated with 90 MeV Si7+ ions at different fluences in the range from 1 × 1012 to 6 × 1013 ions cm−2. The investigations on structural and surface modifications were made (after irradiation) by Raman spectroscopy and atomic force microscopy (AFM), respectively. Raman spectroscopic studies reveal that C70 is not completely transformed into amorphous carbon at a fluence of 6 × 1013 ions cm−2. Swift heavy ion irradiation generates nanometre size conducting tracks in fullerenes. For 90 MeV Si ions irradiated C70 fullerene, the damage cross-section (σ) and radius of damaged cylindrical zone were estimated from Raman spectra, to be ∼0.32 × 10−13 cm2 and ∼1.01 nm, respectively, using vibrational modes of C70. From AFM study it is clear that the film irradiated at a fluence of 3 × 1012 ions cm−2 shows maximum roughness. Contact angle measurements have been performed to know about hydrophilic or hydrophobic nature of fullerene C70 thin films.

Risk constrained short term electricity procurement for open access consumer in India

Open access is a major power sector reform in energy deficit India, and encourages short term trading for meeting variations in demand. An open access large consumer in India, can participate in short term trading through bilateral contracts, power exchanges (PXs) or unscheduled interchange (UI) transactions. In addition, it needs to satisfy obligations of renewable purchase. Prices of PXs day ahead market are uncertain, while UI charges for frequency variations vary widely due to real time deviations in withdrawals. Considering these uncertainties in the backdrop of Indian power sector, this work proposes an optimal short term power procurement strategy for large consumer, from available trading options. A small self generation facility and demand flexibility is also considered. A practical case study of Indian open access consumer is considered to show the effectiveness of proposed approach.

Impact of short term electricity procurement of an open access consumer on Indian grid

Pooja Sharma; Urmila Brighu; Parul Mathuria; Anoop Singh

Unscheduled Interchange (UI) mechanism has emerged as a powerful tool for maintaining grid discipline, penalizing the market players, causing deviations in the system. A buyer pays UI penalty for over-withdrawal of power more than the scheduled one based on the grid condition. Such buyers having demand fluctuations may end up paying UI penalty at the real time. This paper proposes a planning model for a large open access consumer in India, purchasing from bilateral contracts and multiple Day Ahead Markets (DAMs). The proposed model can shift consumers expected demand by accounting the UI deviations to minimize procurement cost. A small self generation unit and renewable purchase obligations are also considered. This work considers price uncertainty of both markets. The overall problem of cost and risk minimization is handled by mean variance approach. Results indicate that the consumer can plan demand scheduling for the planning period as well as can help in improving grid frequency at the real time.
