  1. 1. Structural analysis of HZO thin film and electrode using X-ray diffraction

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Elliot Winsnes; [2024]
    Keywords : HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

    Abstract : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. READ MORE

  4. 3. Battery Storage as Grid Reinforcement for Peak Power Demands

    University essay from Linköpings universitet/Energisystem

    Author : Jesper Hilleberg; [2023]
    Keywords : Battery Storage; Battery Energy Storage System; Grid Reinforcement; Flexibility; Lithium-ion battery; li-ion battery; Large Scale Grid Storage; BESS; Energy Storage; Peak Power Demand; Batterilagring; Batterilagringsystem; Nätförstärkning; Nätförstärkningsåtgärd; toppeffektlaster; Flexibilitet; Flexibilitetslösning; litiumjonbatteri; li-ion batteri; BESS; energilagring;

    Abstract : An increased amount of intermittent electricity production, more electric vehicles (EV), and an overall electrification of society may all cause a higher variability between the balance of supply and demand on the electric grid. Battery storage has been identified as a solution to the emerging problem asit can be charged during hours of low power demand and then discharged to help meet the power demand during peak loads.

    Keywords : SME; Solar cells; Gävleborg County; Self-consumption; Matching;

    Abstract : Increases in electricity prices in Sweden during the second half of 2021 have created a great deal of concern among companies in Sweden. Some companies report that they have stopped their production temporarily when electricity prices have been high. READ MORE

  6. 5. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Isabelle Löfgren; [2022]
    Keywords : impedance analysis; PV-STATCOM; SSCI; SSO; SSR; sub-synchronous control interaction;

    Abstract : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. READ MORE
