Adequacy Assessment of Integrated Nepal Power System

Abstract

Modern electrical power systems have the responsibility of providing a reliable and economic supply of electrical energy to their customers. The economic and social effects of loss of electric service can have significant impacts on both the utility supplying electric energy and the end users of the service. Maintaining a reliable power supply is a very important issue in power system design and operation .The developing country including Nepal more often does not follow the modern planning criteria for system planning due to which we have to face problems like load shedding. This work is an exercise to detail reliability analysis of INPS using different reliability indices. The INPS has been divided into three regions and the reliability indices are found separately for each region. The two reliability indices LOLE and EENS are found to check the adequacy of generation. The load data and generation data used are all real from the only one utility of Nepal, NEA. The calculations are done according to the theory of reliability of power system on MATLAB programming. The results obtained in this work are quite satisfactory and represents the present condition of INPS.

Composite reliability evaluation of Integrated Nepal Power System

“…Different methods have some pros and cons [5]. The HLI reliability indices of INPS are evaluated by the analytical method [6] The power system is stochastic. The random behavior of the system can be properly incorporated into the simulation method.…”
