The Plaid Cymru leader will say she is determined to lead her party into government at the assembly elections.
Ms Wood will attack Labour's record, accusing First Minister Carwyn Jones's government of failing.
She will say Scotland has a nationalist government with a track record of making the most of its powers.
"In Wales we have a double whammy: a nation without basic powers and a government that wouldn't have a clue what to do with them," Ms Wood will tell the conference.
Plaid and the SNP are long-standing allies.
But while the SNP has overtaken Labour as Scotland's biggest party, Plaid goes into next May's devolved elections as the assembly's third party - behind Labour and the Conservatives.
Ms Wood will say: "Indeed it is my determined resolution to lead Plaid Cymru into government next May because that represents the change Wales needs - the future our people deserve.
"It is my hope therefore to return to your conference next year and congratulate you on yet another famous election success and to do so as the newly-elected first minister of Wales."

Is the NHS better since devolution and has the Welsh government delivered on its promises?
Firstly Dr Alan Rees, of the Royal College of Physicians, said there has been huge improvements over recent decades but the health service has been a victim of its own success.
Plaid Cymru health spokesperson Elin Jones AM argues that the NHS and health boards have failed to manage their finances.
Dr Tony Calland, of the British Medical Association, said the Welsh government had done its best but had underestimated the problems.

The Rift headset will be released early next year. Until now, only a "developer" version had been sold.
The deal with Microsoft, the tech giant that makes the Xbox, means Oculus owners will be able to stream Xbox One games to the headset and see them as if they are being viewed on a huge "home cinema" screen.
The new headset will compete with rivals such as Sony's Morpheus and HTC's Vive.

Sandra Charles' spent 375 hours knitting 350 strands out of thousands of recycled label transfers
Ms Charles, of Somerset, got the idea while at a recycling centre.
Her work is on display with other students' projects at Nottingham Trent University, including lingerie inspired by wartime love letters, and two-dimensional clothing.
Ms Charles said: "I wanted to develop my sculpture work and my knitting. I looked at different techniques and saw arm knitting.
"It's very difficult to describe but basically uses your arms as needles. It took three hours to make each strand at first - I got repetitive strain injury at one point and couldn't do any more for a couple of days."
Other work includes Chloe Bampton, a fashion design student, who created lingerie inspired by her grandparents' war time love letters.
Ms Bampton, from Dullingham, Cambridgeshire, said: "When you read through their letters you imagine yourself in a different way of life completely.
"They are so romantic. We've lost touch with the era of hand letter writing and courting and I wanted to design lingerie which provided an alternative to the modern day shock element."
Her grandparents Dennis and Kathleen Algar married shortly before Mr Algar was sent to fight. He spent four years in a Japanese prisoner of war camp.
Meanwhile, South Korean student Dahye Jee designed concept clothing which appears two-dimensional, inspired by vintage paper dolls.
All the work is on display until 6 June.
