摘要

In recent years there has been rapid worldwide growth in Renewable Energy (RE) generation but it isoften seen as a less valued source [1] because its variability can cause operational difficulties underhigh penetration levels. This paper describes the successful management of high penetration REleading to > 50 % reduction in annual diesel consumption. Maximum wind energy penetration levelsare typically 20-30 % - with instantaneous peaks exceeding the 50 % demand level. Two questionsoften arise: what is the limit for high RE penetration and what major factors define this limit?The paper discusses the issue of high RE penetration in small isolated systems, characterized by highresource variability and non-synchronous generation. RE sources also displace synchronousgeneration which reduces the availability of traditionally supplied ancillary services: reserves, inertia,fault level and voltage regulation. This paper addresses integration of wind energy in a small islandedsystem including preparation for operation of the system without a diesel generator when windconditions permit. The paper concludes that this is technically and economically feasible and it willcontribute to further increases in RE within a Remote Area Power Supply (RAPS) system. The systemcan be successfully operated with wind energy penetration exceeding 50% but requires carefulconsideration of enabling technologies, which supply the complementary services not provided byWind Turbine Generators (WTG).
