Machinery for Renewable Power Generation has gone through several technological advances. This special issue will address the new frontiers and the state of the art of renewable energy technologies and their power generation machinery, design complexity, costs, energy and operational limitations. It provides a forum for the presentation of new research, development and applications of renewable power generation machinery. Demonstrations and experimentally based research are particularly welcome. Research that explores issues where the characteristics of the renewable energy source impact on the power conversion and where the wider system control or operation are central to the challenge of integration are particularly encouraged including energy storage. This special issue is technology focused covering design, demonstration, modelling and analysis, but papers covering techno-economic issues are also welcome. The purpose of this special issue is to reflect the state of the art in challenges faced by renewable power generation machinery developers and present the most important and relevant advances to overcome the challenges.
This special issue invites papers that cover the following topics of interest (but not limited to these):
• Generic & Applied Research on Renewable Power Generation Fluid / Electrical Machinery
• Computational & Experimental Modelling
• Device Development & Power take off
• Computational Fluid Dynamics & Control
• Economics & Condition Monitoring
Position papers and state of the art reviews are especially welcome.Dr. George A. Aggidis

Title: Detailed Study on Closed Stator Slots for a Direct Driven Synchronous Permanent Magnet Linear Wave Energy Converter

Abstract: The aim of this paper is to analyze how a permanent magnet linear generator for wave power behaves when the stator slots are closed. The common way to design the stator geometry is to use open slots to keep the magnetic leakage flux between the stator teeth low. By doing this, harmonics are induced in the magnetic flux density in the air-gap due to slotting. The closed slots are designed to saturate to keep the permeability low. This reduces the slot harmonics in the magnetic flux density but will also increase the flux leakage between the stator teeth. An analytical model has been derived to study the flux through the closed slots and the result has been compared with finite element simulations. The result shows a reduction of the cogging force and a reduction of the harmonics of the magnetic flux density in the air-gap. It also shows a small increase of the total magnetic flux entering the stator and an increasing magnetic flux leakage through the closed slots.
