Abstract

Renewable energy has its own application potential and limitation, according to the in-situ natural force. If appropriate renewable energy sorts are selected and operated complementarily, the overall performance and potential supply time are anticipated to be higher than those operated individually. For example, electricity generation by solar and wind power are limited by the local sunshine and wind quality. In coastal areas, these could be well arranged and operated complementarily to raise the electricity supply quality and obtain the maximum natural resource. This study establishes a complementary operation system, consisting of 0.5KW PV, 1.4KW small-scale wind power, batteries, AC/DC DC/AC inverters, etc. A 1KW simple desalinator was selected as the power consumer and powered by this complementary system. Nodal electric data and system performance were measured. HOMER, developed at the National Renewable Energy Laboratory, USA, was used to illustrate and evaluate the technical and economic aspects in planning the desalination in a conventional land aqua-farm in Taiwan.

In contrast, if suitable forms of renewable energies are selected and used complementarily, then the power
