project

hello, please help me to find circuits in LTspice about the topic of "designing optimal distribution interface of hybrid renewable energy (photovoltaic and wind) for smart home"

Welcome to ETO!
It is impossible to advise you when the topic is so vague. What is 'optimal'? What needs supplying/controlling in this smart home? What energy levels are involved? You need to confine your request to more specific parts of the system, e.g. voltage/current control, storage battery requirements, signal conditioning, ......etc.

And you need to do some work yourself instead of expecting someone to hand you an answer...

For starters, learning to write a more descriptive title for you posting would help...
