  1. 1. The influence of short-term forecast errors in energy storage sizing decisions

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Adrian Bagger Toräng; Viktor Rönnblom; [2022]
    Keywords : Energy storage system; Pumped hydro energy storage; Electricity price forecast; Forecast error; Sizing; Robust decision making; Energilagringssystem; Pumpkraftverk; Elprisprognos; Prognosfel; Dimensionering; Robust beslutstagande;

    Abstract : Pumped hydro energy storages commonly plan their operations on short-term forecasts of the upcoming electricity prices, meaning that errors in these forecasts would entail suboptimal operations of the energy storage. Despite the high investment costs of pumped hydro energy storages, few studies take a holistic approach to the uncertainties involved in such investment decisions. READ MORE

  3. 2. Flexibilitet i virkestransporter på järnväg : möjligheter och kostnader : effekter av säsongsmönser och avvikelser från planerade tågflöden

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : Ida Sjölling; [2022]
    Keywords : virkesförsörjning; tåg; störningar; risk; multimodala transporter;

    Abstract : Behov av flexibilitet i virkesförsörjningen uppstår eftersom det är en dynamisk verksamhet. Störningar i tillverkningsprocessen kan ge förändring i efterfrågan, störningar i transporter kan ge förändrade behov från olika transportslag och störningar i anskaffning av virke ger nya flöden.

  4. 3. Open Source Grid Expansion Models for the EU Project Spine

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

    Author : Akshaya Tammanur Ravi; [2021]
    Keywords : Expansion Planning; Renewable Energy Sources; Operational Variability; Representative Days; Long-term Uncertainties; Stochastic Optimization; Utbyggnadsplanering; Förnybara energikällor; Variabel driftsituation; Representativa dagar; Långsiktiga osäkerheter; Stokastisk optimering;

    Abstract : Modern power systems are at the forefront of addressing the transition towards a decarbonized energy system, with increased integration of renewable energy sources becoming the key means to achieve the same. In this context, an expansion planning problem provides a decision support framework for investments in new generation and transmission assets over a long time-frame, addressing a wide range of technical and economic criteria aligned with national policies.

  5. 4. Sustainability assessments of research projects: exploring the case of Sustainability Readiness Level (SRL)

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Nike Stadler; [2020]
    Keywords : Research Policy; research evaluation; sustainability; Sustainability Readiness Level; grant review; Earth and Environmental Sciences;

    Abstract : This study explores the cross-section between sustainability assessment and research reviewing- and evaluation at an early development stage of emerging technical solutions´ by conducting a case study on Sustainability Readiness Level, a tool used in the application and reviewing process of the Strategic Innovation Programme (SIP) BioInnovation. The aim of the thesis is to gain a deeper understanding of how sustainability assessments can be integrated into R&D projects and to get an understanding of the perception of SRL among its users (applicants and reviewers).

  6. 5. New challenges for transport planning : the institutionalization of mobility as a service in the Stockholm region

    University essay from KTH/Urbana och regionala studier

    Author : Erika Kriukelyte; [2018]
    Keywords : mobility as a service; institutional theory; institutionalization; actor network;

    Abstract : The new trends and challenges are transforming the traditional way of thinking and planning transport systems, with concepts like mobility as a service (MaaS) developing as a result of these transformations. Whilst, the concept of MaaS is still considered new, it is attracting attention from both researchers as well as actors involved within the transport sector. READ MORE
