【Feasibility Limits for a Hybrid System with Ocean Wave and Ocean Current Power Plants in Southern Coast of Brazil】

Ocean waves and currents have characteristics of relative predictability that differentiate them from other renewable resources. This better predictability can guarantee priority investments in the development of alternative energy sources. This article presented a pre-feasibility study of a hybrid system to be operated for obtaining energy supplies through ocean wave energy and ocean current energy conversion devices on the southern coast of Brazil, along the north coast of the State of Rio Grande do Sul. The study was based on simulations performed with the Homer Legacy software and shows the limits for some parameters that establish the technical and economic feasibility for this system.

◎要像水能调和百味一样，学会与世上三种人相处：一是与能人相处干大事；二是与好人相处干成事；三是与坏人相处不干坏事。这样的人，一生常遇贵人，不遇敌人；常遇好人，不遇仇人；常遇善人，不遇小人，一生如意吉祥。

We should learn to get along with three kinds of people just like water to mix up various flavours. Firstly, we should do great deeds with the talented persons; secondly, we should do good deeds with the kind persons; thirdly, we can’t do bad things with the bad persons. So that we will often meet helpers and kind persons and have good luck in the whole life; and we will not meet enemies and the petty men.
