  1. 1. Distributed Photovoltaics, Household Electricity Use and Electric Vehicle Charging : Mathematical Modeling and Case Studies

    Author : Joakim Munkhammar; Joakim Widén; Ewa Wäckelgård; Jesper Rydén; Peter Lund; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Photovoltaics; Household Electricity Use; Electric Vehicle Charging; Markov Chain Modeling; Probability Distribution Modeling; Data Analysis; Self-Consumption; Grid Interaction.; Engineering Science; Teknisk fysik;

    Abstract : Technological improvements along with falling prices on photovoltaic (PV) panels and electric vehicles (EVs) suggest that they might become more common in the future. The introduction of distributed PV power production and EV charging has a considerable impact on the power system, in particular at the end-user in the electricity grid. READ MORE

  4. 4. Urban building energy modeling : A systematic evaluation of modeling and simulation approaches

    Author : Fatemeh Johari; Joakim Widén; Joakim Munkhammar; Olga Kordas; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Urban building energy modeling; Urban energy Planning; Bottom-up energy modeling; Thermal zoning; Model complexity;

    Abstract : Urban energy system planning can play a pivotal role in the transition of urban areas towards energy efficiency and carbon neutrality. With the building sector being one of the main components of the urban energy system, there is a great opportunity for improving energy efficiency in cities if the spatio-temporal patterns of energy use in the building sector are accurately identified.

    Abstract : The global market for photovoltaics (PV) has increased rapidly: during 2014, 44 times more was installed than in 2004, partly due to a price reduction of 60-70% during the same time period. Economic support schemes that were needed to make PV competitive on the electricity market have gradually decreased and self-consumption of PV electricity is becoming more interesting internationally from an economic perspective.
