DESIGN OF CONSUMMER THERMAL SUBSTATIONS FOR THE INTEGRATION OF DISTRIBUTED SOLAR TECHNOLOGIES IN DISTRICT HEATING SYSTEMS [PDF]

open access: yes, 2018
In most cases, building service designers choose between Solar thermal (ST) and District Heating (DH) technologies for their integration in buildings. By doing so, only a fraction of the buildings within a particular district is used for ST, while at the

Investigation of the Impact of XLPE Cable Ageing on Impedance Mismatch Characteristics and Unbalanced Behaviour in Hybrid Operation Systems

open access: yesHigh Voltage, EarlyView.
ABSTRACT In the Hainan–Guangdong interconnection project, oil leakage in oil‐filled cables required replacing the faulty core with a single core from a three‐core cross‐linked polyethylene (XLPE) cable, leading to mixed operation of XLPE and oil‐filled cables.

Correlated Transient Response of Buried Cables and Lightning Channel Radiation of Return Strokes of Five Rocket‐Triggered Lightning Strikes

open access: yesHigh Voltage, EarlyView.
ABSTRACT Data from five rocket‐triggered lightning flashes are adopted to analyse the correlated transient response of buried cables and lightning channel radiations. These five flashes have the same termination point that is right above the buried cables and involve a total of 32 return strokes.

Analysis of curtailment at The Geysers geothermal Field, California [PDF]

open access: yes, 2020
Geothermal energy has traditionally been viewed as a baseload energy source, but the rapid growth of intermittent renewable energy has led to a need for more flexibility in power generation to avoid mandatory curtailment imposed by grid operators.

Residential demand management using individualised demand aware price policies [PDF]

open access: yes, 2016
This paper presents a novel approach to Demand Side Management (DSM), using an “individualised” price policy, where each end user receives a separate electricity pricing scheme designed to incentivise demand management in order to optimally manage ...

Regional Infrared and Visible Image Registration for Distribution Substation Areas With Wide Depth of Field

open access: yesHigh Voltage, EarlyView.
ABSTRACT Infrared and visible image registration is a key task in automated distribution network inspection. Previous approaches typically apply a single homography to align infrared and visible images leading to local misalignment. To address this, this study proposes a novel region‐based registration algorithm specifically designed for wide‐depth ...

Lead-Acid Battery Sizing for a DC Auxiliary System in a Substation by the Optimization Method

open access: yesEnergies, 2019
Lead-acid batteries are the most frequently used energy storage facilities for the provision of a backup supply of DC auxiliary systems in substations and power plants due to their long service life and high reliability. It is possible to define the load

Long-Term Voltage Stability Assessment of an Integrated Transmission Distribution System

open access: yes, 2017
Long-term voltage stability assessment (VSA) of independent transmission (T-VSA) and distribution (D-VSA)systems have been studied since long to estimate load margins. However, their impacts on each other have been neglected due to simplified assumptions
