India has an exclusive ministry for renewable energy development which is known as the Ministry of Non-Conventional energy Sources (MNES). Since its foundation has been laid, one of the world�s biggest and most promising programs on renewable energy have been launched by the Ministry. Significant progress is being made in power generation from renewable energy sources because of great deal of efforts put up by MNES. The expansion of investments has brought benefits of employment, development, and growth in the quality of life, but only to the major cities.

To deal with these challenges, an EV Aggregator (EVA) can employ Vehicle-to-Grid (V2G) technology to synergize grid integration of renewable energy resources (RESs) and EVs. EVA provides smart coordination between SO and EV owners providing grid support services through V2G charge/discharge scheduling of EVs. However, energy market prices uncertainties involved in market operation would significantly affect profit and behavior of EVA. Proposed work models an integrated DR and risk-aversive V2G scheduling of EVA for its expected profit maximization and effective utilization of photovoltaic (PV) generation from rooftop solar charging park incentivizing EV owners and flexibility enhancement to SO. Revenue of EVA is due to regulation and charging services to SO and EV owners respective...

Nevertheless, PLO faces multiple uncertainties in market prices viz. energy and regulation prices and mobility behavior dynamics, affecting severely its V2G operational behavior. Proposed work models integration of Price-based Demand Response Program (PBDRP) by PLO, to utilize the flexibility of EV owners, deal with the uncertainties, improve its market operations and maximize its expected profit. Proposed stochastic programming problem is formulated by modelling these uncertainties using Monte Carlo Simulation and Kantorovich Distance-based backward reduction algorithm. TOU price design by PLO from EV owners' perspective minimizes charging cost. Conditional-Value-at-Risk (CVaR) is employed as a coherent risk measure for risk-management. The results from realistic case studies illustrate that decisions based on the proposed approach provide better trade-off in terms...

Voltage instability is a quite frequent phenomenon under such situation rendering degradation of power system performance. In order to avoid system voltage collapse and blackouts, power system is to be analyzed in view of voltage stability for a wide range of system conditions. This paper discusses the use of line voltage stability indices termed as fast voltage stability index (FVSI) and line stability index (Lmn) in order to determine the critical line. The line with least stability margin is ranked highest indices value is identified as theoretical line. The performances of the indices are investigated for the IEEE 14 bus test system at different loading using MATLAB simulations. KeywordsCritical line, voltage collapse, Fast voltage stability index (FVSI), Line voltage index (LMN). __________________________________________________***...

Parkinglot must be designed ensuring of optimal charging scheduling of EV fleet with the primary objective for maximizing profit of PLO. Installation of solar rooftop PV array at work-place provide the key solution of aforementioned challenges. Energy price of grid vary due to load demand on grid and PLO faces price volatility issue. To resolve this issue, PLO computes Quantity Bound (QB) of uncoordinated EV charging load by estimating overlying area. QB indicates higher usage of the available solar generation so that extreme number of EVs are charged over the solar generation and small amount of electricity is drawn at peak hours when price of energy is relatively high. The algorithm used to reduce the dependency on the grid and shift a load of EV fleet from the grid to PV generation that increases the profit of PLO for coordinated charging of EVs by using the solar out...
