The first decade of the twenty first century saw the Indian electricity sector witnessing fast paced structural changes. Regulatory intervention and policy thrusts have been the significant drivers of this change. The utilities have also adapted to these changes. This paper outlines the various milestones crossed in the first decade and the newer challenges that the Indian electricity grid has to face in the coming years. Smart Grids would be the key to handle complexities arising out of the large meshed networks and with increasing penetration of renewable generation.
The paper aims at quantifying voltage control/reactive support and apportioning the cost incurred to consumers in a physically-based manner. Voltage control/reactive support is basically an ancillary service which is strongly associated with the reliability of the network. In a restructured environment there is no built-in incentive to provide ancillary services as a part of energy sales. Therefore, any such service should be sought and paid for appropriately. This requires that a proper pricing scheme be devised which guarantees both technical and economic feasibility. In the proposed method, voltage sensitivity indices computed at various buses are used as weighting factors to price the voltage control service at the respective buses. A study illustrating the proposed method was carried out on a modified IEEE 30 bus system. The economic reasoning of the method is presented along with some suggested methods for determining the value of reactive power production costs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
