Uncertain accessibility estimation method for offshore wind farm based on multi‐step probabilistic wave forecasting

IET Renewable Power Generation, 2021
Accessibility estimation is significant to the offshore wind farm operation and maintenance (O&M) due to the extremely limited weather window and its sensitive effects on O&M tasks. Wave forecasting can be one solution to help maintenance decision‐making.

Primary Energy Factor of a District Cooling System

Strojniški vestnik - Journal of Mechanical Engineering, 2016
The primary energy efficiency for various energy-related processes can be calculated using the primary energy factor (PEF). In this paper, the PEFs of district cooling systems (PEFDC) for different types of cold production are derived. These concern cold production with an absorption chiller driven by different available sources and cold production ...

Tools for Planning Energy Efficient District Systems [PDF]

Sustainable Places 2018, 2018
An open-source planning tool for the evaluation district cooling systems is developed within project INDIGO. The tool is based on optimisation model consisting of a defined set of components in a district cooling (DC) system. The approach links up the whole energy chain from consumption to resources achieve an optimal solution.
