1. 1. Variation Management Strategies for Future Construction Sites: A study to address role of an equipment rental business in the energy transition

   University essay from

   Author : Ellen Blanksvärd; Frida Svensson; [2023-09-21T12:07:03Z 2023-09-21T12:07:03Z 2023 2023]
   Keywords : battery storage; variation management; flexibility services; peak shaving; load shifting; demand side management; rental business; electrification; construction equipment; construction sites;

   Abstract : Construction sites are facing challenges with high power peaks due to electrificationof heavy equipment where potential consequences are increased power tariffs locallyand risk of limited power supply. Another development is an increased intermittentpower supply due to more wind- and solar power in the electricity system, whichcauses price fluctuations. READ MORE

3. 2. Dispatch Optimization of the TES.POD Cluster using Mixed-Integer Linear Programming Models

   University essay from Uppsala universitet/Elektricitetslära

   Author : Ivar Wikander; [2023]
   Keywords : Optimization; Electricity dispatch; Mixed Integer Linear Programming; MILP; Solar PV; Microgrid; Energy Transition; Optimering; Solkraft; Linjär programmering; Elnät;

   Abstract : With increasing shares of variable renewable energy sources in the power mix, the need for energy storage solutions is projected to increase as well. Storage can in such combined systems help mitigate the issues with relying on intermittent sources by time-shifting the supply and smoothing out frequency fluctuations, to name some examples.

4. 3. Analysis of Prerequisites for Connection of a Large-Scale Photovoltaic System to the Electric Power Grid

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

   Author : Fanny Lilja; [2021]
   Keywords : solar energy; large-scale photovoltaic system; PV; Swedish power system; power output fluctuations; voltage quality; voltage variations; reactive power compensation; PSS E; solenergi; storskalig solcellsanläggning; PV; Sveriges kraftsystem; effekförändringar; spänningskvalitet; spänningsvariationer; reaktiv effektkompensering; PSS E;

   Abstract : The deployment of large-scale photovoltaic (PV) systems is rising in the Swedish power system, both in quantity and in system size. However, the intermittent characteristics of the PV production raises questions concerning the stability in the electric power grid, and power output fluctuations from the PV systems can lead to voltage quality issues.

5. 4. Power Plant Operation Optimization Economic dispatch of combined cycle power plants

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

   Author : Stefano Rosso; [2019]
   Keywords : ;

   Abstract : As electricity production from renewable sources increases, higher flexibility is required by fossil fuel generation to cope with the inherent fluctuations of solar and wind power. This results in shorter operating cycles and steeper ramps for the turbines, and more uncertainty for the operators. READ MORE

6. 5. Battery energy storage design and operation in an HVDC-system with WPP clusters

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Harald Åkesson; [2019]
   Keywords : BESS; Energy storage; State of charge; Windpower; HVDC; Technology and Engineering;

   Abstract : The electricity sector is in the beginning of a large shift from centralized dispatchable production to distributed variable production. With this necessary change, new challenges arise. One crucial challenge is related to upholding the system balance in the power grid. READ MORE
