Abstract


Reliability is the core element measure to be taken into account in electrical power system planning, design and in operation. This reliability of power system is viewed as the probability of providing uninterruptable/continuous power supply to the consumers in an efficient way meeting their load demand. The objective of this paper is to study, analyze and examine the reliability of Tamil Nadu power grid by accounting the load demand for the year 2015. For an effective and error free analysis of this reliability, generation reliability indices of Loss of Load Probability (LOLP) and Energy Not Served (ENS) are used as reliability deciding criteria. In accordance with the objective, the reliability analysis for the restricted peak demand of the state of Tamil Nadu for the year 2015 has been made using Wien Automatic System Planning IV (WASP IV). The Progress Report for 2015 issued by Southern Regional Power Committee is used for collecting official and authentic data for the study. Methodology for this study is formulated by applying Forced Outage Rate (FOR) at two different ways whereby reliability indices are analyzed. The study reveals that in the first approach FOR is hypothetical as per its commencement period of the plants, where as in second approach deals with approximate unavailability data. Attempt is made to improve the reliability in Tamil Nadu Power Grid by adapting to expected measures. This analysis is made by applying Demand Side Management (DSM) with the implementation of energy sufficient programs. The results showed that there is a reduction in the Loss of Load Probability and Energy Not Served when energy efficient program in demand side is adapted.

Keywords
