Nelu, Typically invalid_grant means one of the information was not filled out correctly (e.g., putting developer token in as the client secret, etc), or that the refresh token is invalid, or that the original authorization URL may have missed critical parameters, such as using offline access.
Usually carefully following the Authentication guide <https://developers.google.com/adwords/api/docs/guides/authentication> would get you a working refresh token that can be re-used in most scenarios.
