Gathering electrical production from multiple devices at sea into a single transmission line to shore is a significant challenge for the Marine Renewable Energy (MRE) sector. The power aggregation question is particularly sensitive for MRE platforms combining distinct devices such as wind turbines and Wave Energy Converters (WECs). These combined platforms were examined in the EU FP7 project -MARINA Platform- to investigate potential synergies between MRE converters through the sharing of platform, electrical components, maintenance activities, etc. This paper will investigate optimal power aggregation methods to achieve cost savings and risk reduction, using a case-study platform concept combining one wind turbine and twenty WECs. The benefits from sharing components such as DC link, inverter and transformer will be discussed, comparing two distinct power aggregation methods. The different options will be assessed through a lifecycle cost analysis combined with a Reliability, Availability, Maintainability (RAM) assessment, quantifying the impact of failures and maintenance activities on energy production availability and costs. Optimal power aggregation methods will be highlighted based on initial equipment investment; costs induced by failures and maintenance activities over the platform lifespan; and resulting loss of income due to power production interruptions.

Assessment of renewable energy based micro-grids for small communities Sadati, S.M. Sajed; Taylan, Onur; Sustainable Environment and Energy Systems (2016-7) Deploying renewable energy systems to supply electricity faces many challenges related to cost and variability of the renewable resources. One possible solution to these challenges is to hybridize renewable energy systems with conventional power systems and include energy storage systems. In this study, the feasibility analysis of two cases for electricity generation systems as (i) photovoltaic (PV)-battery-pumped hydro system (PHS) and (ii) PV-wind-battery are presented as a Renewable Energy Micro-Gr...
Sizing of Photovoltaic-Wind-Battery Hybrid System for a Mediterranean Island Community Based on Estimated and Measured Meteorological Data Sadati, S. M. Sajed; Jahani, Elham; Taylan, Onur; Baker, Derek Keıth (2018-02-01) Deploying renewable energy systems (RES) to supply electricity faces many challenges related to cost and the variability of the renewable resources. One possible solution to these challenges is to hybridize RES with conventional power systems and include energy storage units. In this study, the feasibility analysis of a grid-connected photovoltaic (PV)wind-battery hybrid system is presented as a microgrid for a university campus-scale community on a Mediterranean island. Models for PV and wind turbine syste...
Operational Ecosystem: Ecosystem forecast products to enhace marine GMES applications (OPEC) Salihoğlu, Barış(2014-12-31) OPEC will undertake research and development to develop Operational Ecology to augment the capabilities of the GMES Marine Service. Using the Marine Service as a framework, OPEC will OPEC will contribute ‘to the establishment of innovative new GMES products or applications by’ establishing the infrastructure for the performance of ecology in the European Regional Seas by implementing a prototype regional ecological Marine Forecast System in 4 European Regions (NE Atlantic Baltic, Mediterranean and Black Sea...
Optimal design and operation of land-treatment systems for petroleum hydrocarbons Kivanc, S; Ünlü, Kahraman (1999-04-22) Land treatment technology has been extensively used for the disposal of petroleum hydrocarbon containing wastes. Effective management of land treatment systems requires optimum design and operation of the system in order to achieve the fastest and most complete degradation of petroleum hydrocarbons without contamination of the environment. This paper describes a model that can be used for optimal design and operation of land treatment systems for petroleum hydrocarbon containing wastes. The model is compose...
Performance prediction of underground gas storage in salt caverns Bagci, A. Suat; Ozturk, E. (Informa UK Limited, 2007-01-01) Underground gas storage is a common activity in countries with major transport and distribution gas pipeline infrastructures, which allows to efficiently resolve demand seasonality problems. Subsurface caverns in salt formations are being increasingly used for storage of natural gas. In this study, a real salt cavern having the potential for being an underground gas storage unit was evaluated. A model of the salt cavern was constructed within the gas simulator established for the purposes of this study. The...
