  1. 1. Coincidence Factor and Battery Energy Storage Systems for Industrial Electrical Power Supply : A Field Study of Building 178 at Scania AB, Södertälje

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lucas Wallhager; [2023]
    Keywords : Coincidence factor; Industrial electric load diversity; Velander; Normal distribution; Herman-Beta; Battery energy storage system; Sammanlagringsfaktor; Industriell elförbrukning; Velander; Herman-Beta; Batterier för energilagring;

    Abstract : Coincidence factors have been researched since the late 1800s, as they displays the ratio between the maximum coincidencental power usage of a system, and the sum of the maximum individual loads of the system. Accurate estimations of the highest coincidental power usage allow for minimal material usage when constructing substations, transformers, overhead lines, and cables for power transmission.

  3. 2. A Deep Learning Based Approach to Object Recognition from LiDAR Data Along Swedish Railroads

    University essay from KTH/Fastigheter och byggande

    Author : Egil Morast; [2022]
    Keywords : Deep learning; DGCNN; LiDAR; Object recognition; Railroad; Automatisation; Sweden; Point cloud; Djupinlärning; DGCNN; LiDAR; Objektigenkänning; Järnväg; Automatisering; Sverige; Punktmoln;

    Abstract : Malfunction in the overhead contact line system is a common cause of disturbances in the train traffic in Sweden. Due to the preventive methods being inefficient, the Swedish Transport Administration has stated the need to develop the railroad maintenance services and has identified Artificial Intelligence (AI) as an important tool for this undertaking.

  4. 3. Improving maintenance scheduling with condition monitoring on the electric distribution grid : An economic analysis comparing corrective and predictive maintenance

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Hugo Vincenti; [2022]
    Keywords : Condition-based maintenance; predictive maintenance; health index; failure rate; maintenance scheduling; sensors; economic analysis; simulation; Tillståndsbaserat underhåll; förebyggande underhåll; hälsoindex; felfrekvens; underhållsplanering; sensorer; ekonomisk analys; simulering.;

    Abstract : A growing use of sensors on the electric grid has opened the door to new methods of asset management: Distribution System Operators are now looking into conditionbased maintenance, as opposed to the traditional corrective or time-based methods. As an emerging field, the methodology must be constructed from the ground, with the little data available. READ MORE

  5. 4. Configurable, scalable single-ended sense amplifier with additional auxiliary blocks for low-power two-port memories in advanced FinFET technologies

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Limitha Subbaiah Kumar Nangaru; [2022]
    Keywords : CMOS Complementary Metal Oxide Semiconductors ; DRC Design Rule Check ; Process Corners; FinFET Fin Field Effect Transistor ; IC Integrated Circuit ; LVS Layout Versus Schematic ; Monte Carlo; Nominal Voltage; PDK Process Design Kit ; Power Delay Product; Read Bit Line; Read Word Line; SoC System on Chip ; SRAM Static Random Access Memory ; Threshold Voltage; Technology and Engineering;

    Abstract : System on Chip (SoC) designs contain a variety of Intellectual Property (IP) cores, including digital signal processing blocks, media and graphics processing units, as well as processing core units that employ multiple-port memories to enhance performance and bandwidth. These memories allow parallel read/write operations from the same memory blocks from different ports. READ MORE

  6. 5. Operation planning for power grids with high instalment of dynamically rated components in liberalised electricity markets

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Frida Lundquist; [2022]
    Keywords : Multi-interval real-time markets; Dynamic line rating; Optimal Power Flow; Renewable resources; Ramp-rate; Time inconsistency;

    Abstract : The power grid is a complex system that requires detailed planning and operation of the power sources. As renewable resources are increasing their share of the power mix, there are new criterion and aspects to take into account. Renewable resources such as wind and solar power are intermittent and challenge the planning and operation further. READ MORE
