1. Emission and interaction from domestic installations in the low voltage electricity network, up to 150 kHz
Sammanfattning : This thesis work has focused on conducted emission (up to 150 kHz) from common lowvoltage appliances. The emphasis has been on equipment that contributes to a sustainable energy system: photovoltaic (PV) installations and energy-saving lamps (LED lamps). LÄS MER
2. Power line communication and customer equipment
Sammanfattning : In Sweden, the change from manual meter reading at irregular intervals, to automatic remote meter reading at predefined instants was completed in July 2009. This change is ongoing or largely completed in a number of other European countries as well. Several methods for communication between the meter and the network operator are in use. LÄS MER
3. Stochastic Planning of Smart Electricity Distribution Networks
Sammanfattning : The penetration of intermittent Distributed Generation (DG) brought additional uncertainty to the system operation and planning. To cope with uncertainties the Distribution System Operator (DSO) could implement several strategies. LÄS MER
4. Applications of Unsupervised Deep Learning for Analysing Time-Varying Power Quality Big Data
Sammanfattning : Continuous power quality monitoring allows grid stakeholders to obtain information about the performance of the network and costumer facilities. Moreover, the analysis of continuous monitoring allows researchers to obtain knowledge on power quality phenomena. Power quality measurements result in a large amount of data. LÄS MER
5. Propagation of Supraharmonics in Low-Voltage Networks
Sammanfattning : The need for measures towards a sustainable use of energy has incited the proliferation of devices and systems for the efficient use of electricity. Energy-efficient appliances, equipment for the electrification of transportation, electricity generators from renewable energy sources, and communication protocols, e.g. LÄS MER
