On the wake deflection of vertical axis wind turbines by pitched blades

open access: yesWind Energy, 2023
Wake losses are a critical consideration in wind farm design. The ability to steer and deform wakes can result in increased wind farm power density and reduced energy costs and can be used to optimize wind farm designs.

Performance Assessment of District Energy Systems with Common Elements for Heating and Cooling

open access: yesEnergies, 2021
District energy systems, especially those integrating renewables or low exergy sources, have multiple elements for generating heating and cooling. Some of these elements might be used for both purposes: heating and cooling, either simultaneously or ...

Power Switching Protocol for Two-way Relaying Network under Hardware Impairments [PDF]

open access: yes, 2015
In this paper, we analyze the impact of hardware impairments at relay node and source node (i.e. imperfect nodes) on network performance by evaluating outage probability based on the effective signal to noise and distortion ratio (SNDR).

Performance Optimization With Energy Packets [PDF]

open access: yesIEEE Systems Journal, 2019
We investigate how the flow of energy and the flow of jobs in a service system can be used to minimize the average response time to jobs that arrive according to random arrival processes at the servers. An interconnected system of workstations (WSs) and energy storage (ES) units that are fed with randomly arriving harvested energy is analyzed by means ...
