A multicriteria approach to identify the adequate wind power penetration in isolated grids

Abstract

In this paper, a multicriteria approach to identify the adequate wind power penetration in isolated grids is presented. A discussion concerning the impact of increasing the integration of power generation from renewable sources, in particular wind power, is presented. The assessment of the impact is a decision problem where conflicting criteria (maximization of renewable integration, cost minimization and CO2 emissions minimization) are taken into account. Decision aid procedures based on reference trade-offs and on value functions are then applied to the problem, in a way suitable for a posteriori judgments from a Decision Maker. Finally, the possible preferred solutions are subject to a fully dynamic simulation in order to evaluate the system behavior following a wind disturbance and to determine power quality impacts.
