word choice - "I myself Naresh" as an introduction

I have heard so many times that before starting presentation people introduce themselves like this:

1. I myself Naresh and the topic I am going to present is....



2. Myself Naresh and the topic I am going to present is....


3. This is Naresh and the topic I am going to present is....

In the above examples, which one is correct? Can I use the word myself, when I am introducing myself to someone?
