TRANSFORMING TRANSMISSION SYSTEM DEVELOPMENT FROM REACTIVE TO PROACTIVE THROUGH ELECTRIC VEHICLE FLEXIBILITY

The reduction of carbon emissions in the transportation sector will be aided by the electrification of transportation in RES-based energy systems. However, the inactive addition of electric vehicles is expected to hinder sustainability efforts owing to the rise in power consumption and the significant peak impacts of charging. The three main charging methods for Electric Vehicles (EVs) in Europe are: Smart Charging (SC), Power Charging (PC), and Vehicle-To-Grid (V2G) that give varying degrees of flexibility are examined in this research. This flexibility is compared to the flexibility provided by interconnections. We depict immediate action and future planning in the power organization using the Balmorel optimization tool, and we advance the state of the art by creating new approaches to stand for battery deterioration & at-home charging. Our results show that, up to the year 2050, any rise in charging flexibility reduces system costs, modifies the energy mix, affects spot prices, and reduces CO2emissions.We quantify the reciprocal benefits of flexible charging and variable generation, which limits the economics of permanently installed batteries and causes solar energy to take the place of wind energy in passive charging. The framework that includes and lacks connection development highlights the interplay between European countries in terms of the power price framework of electric mobility. The condition of the nations with the cheapest and most decarbonizes power mix is harmed beneath the most bendable situation at the EU level, even if the best result is achieved. This necessitates an adjusted coordinating strategy at the EU level

Role of Big Data Analytics in Power System Application

Power system sector is the back bone for any country economic growth. In current years, electric power systems have experienced various challenges and technological innovations and have become digitalized with the introduction concept of smart grids. Power systems are being operated in a stressed condition mainly due to the ever increasing load demand, depleting energy resources and environmental constraints on Transmission line expansion. This article focus mainly role of Big Data in various industrialization in brief and specifically applied in the power system studies along with other sectors. Also focuses on using very large data collections, which are difficult to access in standard database systems and also refers to as big data, to manage and monitor the power system. System stability is an significant goal for power engineers to use this huge amount of data to run the system in their rated capacity, power sector can beneficial of various potential solicitation of power system by the use of large-scale data analysis that can help improve the optimization process and helps for the power system to operate in the effective manner

High energy oxygen ion induced modifications in lead based perovskite thin films

The lead based ferroelectric PbZr0.53Ti0.47O3 (PZT), (Pb0.90La0.10)TiO3 (PLT10) and (Pb0.80La0.20)TiO3 (PLT20) thin films, prepared by pulsed laser ablation technique, were studied for their response to the 70 MeV oxygen ion irradiation. The dielectric analysis, capacitance-voltage (C-V) and DC leakage current measurements were performed before and after the irradiation to high-energy oxygen ions. The irradiation produced considerable changes in the dielectric, C-V, leakage characteristics and induced some amount of amorphization. The PZT films showed partial recrystallization after a thermal annealing at 400 °C for 10 min. The phase transition temperature [Tc] of PLT20 increased from 115 °C to 120 °C. The DC conductivity measurements showed a shift in the onset of non-linear conduction region. The current density decreased by two orders of magnitude after irradiation. After annealing the irradiated films at a temperature of 400 °C for 10 min, the films partially regained the dielectric and electrical properties. The results are discussed in terms of the irradiation-induced amorphization, the pinning of the ferroelectric domains by trapped charges and the thermal annealing of the defects generated during the irradiation

High energy Li ion irradiation effects in ferroelectric PZT and SBT thin films

The ferroelectric Pb(Zr0.53Ti0.47)O3 (PZT) and SrBi2Ta2O9 (SBT) thin films were prepared by laser ablation technique. The dielectric analysis, capacitance-voltage, ferroelectric hysteresis and DC leakage current measurements were performed before and after 50 MeV Li3+ ion irradiation. In both thin films, the irradiation produced some amount of amorphisation, considerable degradation in the ferroelectric properties and change in DC conductivity. On irradiation of these thin films, the phase transition temperature [Tc] of PZT decreased considerably from 628 to 508 K, while SBT exhibited a broad and diffuse transition with its Tc decreased from 573 to 548 K. The capacitance-voltage curve at 100 kHz showed a double butterfly loop with a large decrease in the capacitance and switching voltage. There was decrease in the ferroelectric hysteresis loop, remanant polarisation and coercive field. After annealing at a temperature of 673 K for 10 min while PZT partially regained the ferroelectric properties, while SBT did not. The DC conductivity measurements showed a shift in the onset of non-linear conduction region in irradiated SBT. The degradation of ferroelectric properties of the irradiated thin films is attributed to the irradiation-induced partial amorphization and the pinning of the ferroelectric domains by trapped charges. The regaining of properties after annealing is attributed to the thermal annealing of the defects generated during the irradiation

High energy oxygen ion induced modifications in ferroelectric SrBi<SUB>2</SUB>Ta<SUB>2</SUB>O<SUB>9</SUB> thin films

The effects of high energy oxygen ion irradiation on the ferroelectric properties of SrBi2Ta2O9 (SBT) thin films are reported. The films were grown using pulsed laser ablation. Fluence dependant degradation in the ferroelectric properties was observed. The dielectric constant did not show any frequency dispersion in both the unirradiated and irradiated films. After irradiation, the films showed only a decrease in the capacitance value retaining their ferroelectric nature. The switching voltages increased with broader peaks and showed a partial recovery after annealing of the irradiated film. A slim hysteresis loop with decreased Ps, Pr and Ec values was observed. The current density increased to a larger extent. The decrease in the dielectric constant, capacitance and polarization values was to a lesser extent as compared to those of PZT thin films under identical irradiation conditions. The results presented in this paper are illustrative of the fact that the layered perovskites have a stable structure and are less sensitive to extrinsic effects. The relatively high resistance of bismuth layered perovskites such as SBT to the high energy radiation along with the greater fatigue endurance as compared to PZT make them better candidates for applications in memory devices
