Generation of distributed wind energy systems is being investigated as an answer to increased energy demand, since these systems achieve both economic and energy benefits. The purpose of the present article is to demonstrate a new method developed by the authors that optimizes the design of a wind production plant. Traditionally, the design strategy is primarily based on maximizing the economic benefit, to the detriment of other technical aspects. This study proposes a plant design method that, in a future with decreased governmental incentives, adapts the daily production curve to the demand curve with minimal decrease in economic benefit—a highly desirable result. This is achieved by installing generators in several locations that have different features of daily wind speed. In this way a better use of the energy is encouraged.
