1. Coordination of base station energy storage for renewable energy grid : Utilizing Base Station battery storage to stabilize grids with Variable Renewable Energy Sources
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : An increasing amount of variable renewable energy sources are being added to the world’s power grids both as an effort to reduce greenhouse gas emissions in the fight against climate change but also because some of the energy sources with the lowest levelized cost of energy are variable renewable energy sources such as wind and photovoltaics. These energy sources come with inherent difficulties since their energy production is neither constant nor entirely controllable and can cause issues for the power grids if they cause power production and consumption to become imbalanced.

2. Flexibility of electricity usage in private households with smart control : Modelling of a smart control system with the aim to reduce the electricity cost of private households with storage units and photovoltaic systems.
University essay fromAbstract : High electricity prices have become the title of several news articles recently in Sweden and the prices have experienced large sudden fluctuations during certain periods. In this thesis work, a smart control model for the electricity usage in three different households has been developed with the main purpose to minimize the electricity cost. READ MORE

3. Energy Usage in Railway Wayside Object Heating : Modeling of melting of Ice, Estimation of heating power requirement in Switch and Renewable energy feasibility for a Railway system
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Trafikverket operates about 12000 Switches and crossings (SnCs) of which 6800 are equipped with an electrical heating system of 10−30kW power to keep SnCs functional throughout the winters by keeping them free of Snow/Ice. The energy consumption is approximately 200−130GWh/year costing approximately 10−15 million Euros annually. READ MORE

4. A Model-Predictive-Control Based Smart-Grid Aggregator
University essay from KTH/Optimeringslära och systemteoriAbstract : Intermittent energy source usage, such as solar and wind power, is continuously increasing. Intermittent energy sources are highly dependent on prevailing weather conditions, resulting in stochastic electricity generation. The expected stochasticity in electricity generation will cause issues for the current power grid. READ MORE

5. Modeling, Simulations and Analysis of a Demand-Side Management Pilot Project : A collaboration together with Vattenfall R&D
University essay from KTH/Skolan för elektro- och systemteknik (EES)Abstract : The increasing number of renewable power sources gives positive outcomes to a more sustainable society. This change does not come without problems, since the power supply from renewable energy sources is intermittent. This leads to uncertainty to keep the balance between production and consumption.
