Goal planning and risk analysis for distribution reliability indices

This paper deals with a methodology for the assessment of reliability indices in electric power distribution companies based on Monte Carlo simulation models. Risk analysis regarding frequency and duration of interruptions for individual customers can be readily applied for actual distribution systems based on some few network attributes, on the company's general network protection practices and on current system average reliability indices. The paper also shows how investment planning can be extended to consider individual customer reliability indices, so that actions and future system reinforcements are evaluated to meet such established goals. Some applications illustrate the proposed methodology.
