The conventional linear permanent magnet generator (CLPMG) for direct-drive wave energy conversion (WEC) has experienced many drawbacks that are difficult to overcome such as low power density and bulky system volume. To improve power density, this paper proposes a linear magnetic-geared interior permanent magnet generator (LMGIPMG) with tubular topology, which artfully incorporates a linear ma...

Wave energy has a large global resource and thus great potential to contribute low-carbon systems. This study quantifies the environmental impacts of 10MW array 28 point-absorber wave converters, by means process-based life cycle assessment (LCA). Midpoint Cumulative Energy Demand LCA results are presented over 19 impact categories, representing encompassing human health, ecosystems availabilit...

Current wave energy development initiatives assume that available designs have the potential for success through continuous learning and innovation-based cost reduction. However, this may not be case, winning technologies been overlooked. The scenario creation tool presented in paper provides a structured method earliest stages of design technology development. core function is to generate rank...

To achieve cost parity with other renewables, the wave energy sector requires significant reduction. Increasing wind turbine scale is one successful route to reduction in industry. This paper aims at investigating scalability of converters (WECs) and providing a thorough review analysis published data. Unlike turbines for which absorbed increases diameter, WECs complicated varies by WEC type. H...

The exploitation of marine wave energy resource has led to the design numerous Wave Energy Converter (WEC) configurations. power absorption a WEC is tightly related its physical properties and characteristics incoming front. Additionally, operational range limited certain waves. These restrictions are usually limitations in maximum force Power Take-off (PTO) system safety WEC. As result, produc...

Wave Energy Converters (WECs) are an ideal solution for expanding the autonomy of surface sensor platforms such as oceanic drifters. To extract maximum amount energy from these fast-varying sources, a fast power point tracking (MPPT) technique is required. Previous studies have examined management units (PMU) with MPPT circuits, but none them demonstrated their feasibility in real-world scenari...

Abstract: We present two control strategies for an oscillating water column-wave energy converter (OWC-WEC) in the time domain. We consider a fixed OWC-WEC on the open sea with an impulse turbine module. This system mainly consists of a chamber, turbine and electric generator. For the time domain analysis, all of the conversion stages considering mutualities among them should be analyzed based ...
