Electric power industry restructuring in India: present scenario and future prospect
ABSTRACT Power industry restructuring, around the world, has a strong impact on Asian power industry as well. Indian power industry restructuring with a limited level of competition, since 1991, has already been introduced at generation level by allowing participation of independent power producers (IPPs). The new Electricity Act 2003 provides the provision of competition in several sectors. It is felt that the prevailing conditions in the country is good only for wholesale competition and not for the retail competition at this moment. A suitable model is suggested based on the current and future market participants.
Conference Paper: Transmission Charging Practices in ER of Indian Power Utility[Show abstract] [Hide abstract]
ABSTRACT: The paper presents the structure and overview of Indian power system. The development of transmission technology has also been discussed in brief. The paper reviews the philosophy of transmission tariff in Indian scenario. The changing structure of the electricity supply industry is bringing transmission charging mechanism in to new focus. Of course, charging scheme is a complex task and it becomes important to have a comprehensive study of the existing charging scheme. A case study of Eastern region (ER) of existing charging practices has been presented here. The paper endorses the MW-Mile method for transmission charging scheme. Finally, some concluding remarks have been produced.Power & Energy Society General Meeting, 2009. PES '09. IEEE; 08/2009
Conference Paper: Energy audit of a 400/220 kV substation - A case study[Show abstract] [Hide abstract]
ABSTRACT: The paper highlights the necessity of undertaking performance analysis and energy audit study of an electrical installation, more particularly a power substation on regular basis. A 630 MVA, 400/220 kV substation was identified and a detailed study was carried out to assess the various station performance parameters under different operating conditions. It was observed that the installed capacity of the station (transformer) was very large compared to the actual load it had to supply. Thus the station was under loaded and underutilized for the major period of its operation. This reduced the operational efficiency of the station. Secondly the incoming line voltage level was remaining high during most of the period of operation. Presently voltage is tried to be maintained by switching ON the line reactors at the receiving and sending ends of this station, switching OFF one of the 400 kV incoming lines during off peak loading conditions, thus risking the supply reliability. The present study emphasizes on the urgent need for improving the power quality, streamlining and optimizing the station capacity, operations and its loading pattern. Accordingly suggestions are proposed for the same.Utility Exhibition on Power and Energy Systems: Issues & Prospects for Asia (ICUE), 2011 International Conference and; 01/2011

ABSTRACT: Power sector reform is currently underway in several countries of South Asia. This is noticed mainly in the form of change in the investment and ownership pattern, and increasing role for the private investment, both domestic and foreign. These countries continue to be characterized by low per capita consumption of energy, poor quality of energy infrastructure, skewed distribution and inaccessible and costly energy availability. Interconnection of power systems of contiguously located countries and their coordinated operation provide immense technical and economic benefits. The main issue is to run the system in free and fair manner ensuring quality power to the consumer’s at most economical price through safe, secure and reliable operation of the power system resulting in transparent price discovery. Although a number of market models are prevalent in the international arena, the same could not be directly adopted for South Asian Regional power market. This paper is focused on integrating the power market in South Asia, examining the opportunities, benefits, and challenges. Complexity of electricity market in cross border international model scenario has been analyzed in this paper and a model for South Asian Regional Power Pool has been proposed. Demand and supply side bidding scenarios with case studies are presented in the paper.International Journal of Electrical Power & Energy Systems 01/2013; 44(1):146–152.
