An Analytical And Probabilistic Approach For Reliability/ Cost Assessment Of A Wind Power System

Rapid technological progress, combined with falling costs, a better understanding of financial risk and a growing appreciation of wider benefits, means that renewable energy is increasingly seen as the best solution. Global Renewable energy policies, arising from increasing environmental concerns have set very ambitious targets for wind power penetration in electric power systems all over the world. Modern power system aims to provide reliable as well as cost effective power supply to its consumers. Reliability benefits, environmental benefits and operating cost savings from wind power integration should be compared with the associated investment costs in order to determine optimum transmission facility for wind power delivery. In this paper an analytical & probabilistic approach for reliability/cost analysis is presented for determining costeffective transmission line size for wind power delivery. It describes the reliability/cost techniques for determining appropriate transmission line capacity to connect a wind farm to a power grid. The effects of site-specific wind regime, system load, transmission line unavailability, and redundancy on system reliability were studied using a basic system model. The methodology and results shown in this paper should be subsidiary in transmission system planning for delivering wind power to a power system.
