Completed projects

In this project, different measures will be evaluated to see how they can contribute to increased flexibility and better utilization of decentralized solar PV generation. This idea is based on two previous projects where the combination of solar PV and battery storage has been studied from a residential building’s perspective, with the aim of increasing the utilization of the PV energy and reduce the losses in the building, by using storage and demand side management.

The project was funded by the Swedish Energy Agency.

Long-term and continuous maintenance may be more sustainable and appropriate for cultural heritage buildings compared to extensive renovations, both to preserve the value of such buildings and to reduce energy use. Despite this, there is limited knowledge about this and therefore the purpose of the project is to evaluate and compare different renovation strategies to provide increased understanding of a continuous maintenance process for sustainable renovation of cultural heritage buildings.

In order to achieve goals for energy efficiency and reduced greenhouse gas emissions, cities around the world must change their local use and supply of energy. This requires studies of the effects of different urban designs, policy measures and the spread of new technology on the energy performance of entire cities. This project constructs a digital city model that can be used to calculate and visualize energy and power needs as well as greenhouse gas emissions from buildings and transportation at the city level.

Recent studies depict that with respect to the entire life cycle, low-energy buildings do not necessarily outperform the conventional ones and can paradoxically result in an increased energy use. One reason for that is use of new building materials which can eventually require a significant amount of “embodied energy” to manufacture them despite their potential to minimize the operational energy use. The main purpose of this project is to develop and test optimization methods that consider the trade-off between embodied and operational energy and favorably minimize the building's energy use from a life cycle perspective.

Today, computer-driven optimizations are increasingly used in other sectors (e.g. aerospace) to make more sustainable decisions during design. However, their use is still limited in the building sector. The purpose of this project is to develop practical methods based on computer-driven optimizations and test them in several case studies to provide knowledge on how these methods can support sustainable decisions.

Grid integration of new building-related technologies such as PV systems, electric vehicles, batteries, and home energy management systems requires improved spatio-temporal models. In this project, statistical models for solar irradiance, electric vehicle charging and flexible customers are developed. The aim is to propose a methodology that accounts for the complexities involved while still being useful for practical network planning.

This project’s goal is to evaluate whether it is possible to determine where the solar systems in Sweden physically are installed, their power and orientation through a system using aerial imagery or satellite images and an image analysis method that uses machine learning. Both existing and new methods, developed within the project, are evaluated in a Swedish context. An important development is that the method should be able to estimate the power, slope and azimuth of solar systems satisfactorily.

One of the biggest challenges today is to reduce CO2 emissions from fossil fuels to reduce the climate impact, and in Sweden a large part of the fossil fuels is used to drive transport. The goal of this project is to develop new systems with modern photovoltaic (PV) systems and batteries on trucks to reduce carbon dioxide emissions from transport. The project is lead by Ångström Chemistry, but several industrial partners are engaged. Our division contributes by studying the implications if a large share of the trucks are equipped with PV and batteries and connected to the grid.

The purpose of this project is to develop, test and evaluate a method how potential prosumers, living and/or working in culturally valuable environments, are motivated and given opportunities to integrate solar cells. The project will use participatory design methods, building integrated energy thinking, methods for assessing cultural values and energysystem technology in two pilot case studies.

The project will be a continuation of Reza Fachrizal’s PhD project research up to now, in which EV smart charging models for a single residential building and a community has been produced, and its impact on the residential LV distribution grid performance and hosting capacity has been assessed. As a continuation, the proposed project will also be extended for workplace charging stations in cities and its impact in the city grid will also be evaluated. The project also aims to collect actual EV charging data from existing EV charging stations (EVCS) operators to validate the commonly used EV charging models.

Many photovoltaic systems are connected to local electricity distribution networks. An important question is where the systems should be placed and connected for maximum resource and system efficiency. In this project, a method is developed for establishing so-called solar utilization plans by combining solar cadastres with geographical data for various relevant parameters. A case study for Herrljunga municipality shows that a well-planned connection of solar parks is of crucial importance for the utilization of existing infrastructure.

The project District Heating in sustainable future residential areas shows what role district heating can play in future residential areas, both based on a resource efficiency perspective and regarding global carbon dioxide emissions. In particular, the project examines the combination of district heating and electricity production through solar cells. The project also highlights the importance of using the right and defined concepts to assess energy and climate performance.

The purpose of this research project led by RISE is to investigate the conditions for how household batteries should be sized and managed for best usage. The aim is to deepen the knowledge for local storage; how it shall be dispatched and what external services it can provide to the grid. Load profiles from single-family houses are clustered and a PV/battery system is then fitted for each cluster profile. Battery dispatch algorithm is based on artificial intelligence models (AI) for probabilistic prognostication of electrical loads and solar PV generation for optimal battery dispatch.
