I normally don't interact via PMs or visitor messages, so I'll post a response publically. Feel free to post any questions in this thread. I do keep an eye on the threads I've participated in. If you find I've missed a question, you can send me a PM to tell me a question is posted in the public thread.

Good day sir. What i meant is that how can i implement fuzzy logic on energy harvesting? Also, i can't really grasp what is energy harvesting. And what does it do with renewable energy. Do i need to simulate? Thanks for the replies.
First, the term "energy harvesting" is just a way of referrring to the extraction of energy from existing energy sources. Good examples of the sources are solar, wind and ocean energy. This energy is always there, but it takes the proper technology to extract the energy to be useful in modern appications, particularly for conditioning to electrical power systems. A good example is the modern wind farm. Note the use of the word "farm" which again calls to mind the idea of "harvesting". It's just a nice metaphor, that's all.
Second, how you implement fuzzy logic on energy harvesting is something you will need to figure out as part of deciding on your project. However, I can give an example. In solar power, there is the idea of implementing power-point-tracking (PPT). At first, it may sound like PPT means pointing solar cells at the sun to maximize power, but that is not what it means; although that is an important thing to do. PPT means changing the load on the solar cells so that the extracted power is maximized based on the amount of light hitting the cell. If the load is open circuit (infinite resistance), then the voltage is highest, but current is zero. If the load is shorted (zero resistance), then current is highest, but voltage is zero. Since power is voltage times current, both cases give zero power. What is needed is some intermediate load resistance that allows some voltage and some current, but maximum power. One of the many ways to implement PPT is to use a fuzzy logic controller to maximize power by changing the solar cell loading until maximum power is obtained.
If you study the system designs of existing energy extraction systems, you will find many places where parameters need to be adjusted (based on changing conditions such as light level, wind speeds, seastates etc.) in order to maximize power harvesting. If you look at these examples, you may get an new idea for your project.
As far as similation, I would think that a school project would rely heavily on simulations and theory. Then perhaps you could make a small scale model of your idea in order to show proof of concept and validate the simulation models.
