Electricity outage cost estimation for government offices, institutions and few other specific customers

TL;DR: In this article, the authors evaluate customers' electricity supply outage cost for offices belonging to both government and non-government organizations, academic and financial institutions, scientific and technical organizations in a developing country.
Abstract: The customers survey technique for outage cost estimation has been widely used by electric utilities in the developed countries Customers surveys conducted in developing countries are rarely reported Very few outage cost customers surveys conducted in developing countries are reported in the literature for residential, industrial and commercial customer categories However, this is the first attempt to evaluate customers' electricity supply outage cost for offices belonging to both government and non-government organizations, academic and financial institutions, scientific and technical organizations in a developing country The customer survey methodology and its findings are presented in the paper The sector customer damage function (SCDF) is obtained for the surveyed customer category

TL;DR: The main focus of the paper will be on the methods for transmission line congestion cost management and calculation during transmission transactions, and full AC load flow analysis (Newton Rapson) will be used to determine the power system quantities.
Abstract: In our paper we will be reporting our investigations on congestion pricing in a deregulated electricity market using A.C. Power Transfer Distribution Factors (AC-PTDF). In transmission lines, congestion is the important operational issue that often occurs in deregulated system. Congestion in the transmission line restricts the simultaneous delivery of power for set of transaction between generator and load. Thus it is important to manage and remove congestion and to appropriately charge the transmission system users that cause congestion. Many different methods Topological Generation Distribution Factors (D.C.), Traceable flow method, Optimal re-dispatch and Zonal congestion management have been used to determine the congestion cost.

TL;DR: In this paper, the importance of estimating the value of service reliability for electric utility customers is analyzed and the electricity outage cost is estimated for residential and commercial category of customers in ten districts of a northern Indian state of Rajasthan as a case study.
Abstract: This paper analyzes the importance of estimating the value of service reliability for electric utility customers. The electricity outage cost is estimated for residential and commercial category of customers in ten districts of a northern Indian state of Rajasthan as a case study. To obtain responses from the customers a survey questionnaire is framed containing issues related to quality of power supply, losses against outage, customer's desire to have an uninterrupted power supply, compensation for increased outages and choice of alternative action to avoid or nullify the effect of an outage. The outage cost is calculated by two approaches namely preparatory action approach and contingent value approach. Results of this study are meaningful from the utility's perspective in order to ensure the adequate service continuity and customer satisfaction.

TL;DR: In this paper, the authors present the results of an investigation of the direct, short term impacts and costs incurred by residential electrical consumers resulting from local random supply interruptions using a mail survey to determine the residential user's assessment of the cost of electric service interruptions.
Abstract: This paper presents the results of an investigation of the direct, short term impacts and costs incurred by residential electrical consumers resulting from local random supply interruptions. The study used a mail survey to determine the residential user's assessment of the cost of electric service interruptions. The survey obtained user's cost valuation using three approaches. Two of these approaches asked respondents to indicate rate changes that would be commensurate with specified changes in reliability, while the third approach was an indirect worth evaluation based on the preparatory actions a consumer predicted he would take, given a specified (un) reliability. User's valuations are reported for a number of frequency and duration failure scenarios. Variations of user cost estimates are discussed as functions of several user characteristics. Comparisons with the results of other researchers are presented.

TL;DR: In this article, the authors present the results of a residential customer survey conducted in service areas of the Nepal Integrated Electric Power System (NPS) and show that reliability worth evaluation in a developing country is both possible and practical.
Abstract: This paper presents the results of a residential customer survey conducted in service areas of the Nepal Integrated Electric Power System (NPS). The objective was to determine the power interruption costs incurred by the residential customers of a developing country, and extend the customer survey approach to reliability worth evaluation in a developing environment. Interruption cost estimates were obtained using in-person interviews with 944 sample customers. The results indicate the implications of service reliability to residential customers of Nepal, and show that reliability worth evaluation in a developing country is both possible and practical.

Abstract: This paper presents the results of an investigation conducted to determine the costs of electric service interruptions in the commercial and industrial sectors of a developing country. The investigation used in-person interviews of 800 businesses and 300 industries in Nepal. The results indicate the customer implications of service reliability, and show that electric service reliability worth can be assessed in a developing country.
