E-mobility is pivotal in enabling sustainable and technologically advanced urban environments. In line with this, Sweden's electric vehicle fleet is rapidly expanding, thereby increasing the power necessary for charging electric vehicles. If not properly managed and controlled, this increase in power can potentially threaten grid stability and exacerbate grid congestion. 

The primary aim of this thesis was to assess and investigate the potential of a next-generation parking facility at a multifunctional building to be an active part of the city’s distribution grid. The research was guided by the question of to what capacity smart control of a parking facility with a technical system could assist and alter the load demand to generate benefits for both the building and the city’s distribution grid.

This was investigated at Dansmästaren, the first multifunctional building in Uppsala, Sweden. An experimental setup with an electric vehicle charging station and an energy management system was developed at the Ångström laboratory to test and verify control strategies before their implementation at the multifunctional building's parking facility. Thereafter, a second energy management system was developed and implemented at Dansmästaren with the purpose of monitoring and controlling the electric vehicle charging at the parking facility.

The findings of the included papers were divided into two categories. The charging of the electric vehicles can either be assisted by the parking facility's technical system or altered by including the electric vehicle charging in the control for the technical system. Both categories show that a parking facility with a technical system in a multifunctional building can help reduce local grid demand while also providing local benefits for the building.

While the contribution of a single multifunctional building may appear negligible from a grid perspective, the cumulative effect becomes substantial when applied across multiple buildings. Thus, the parking facility at Dansmästaren has the potential to play an active role in the city’s distribution grid through smart charging and the utilization of an energy management system.

Efficient use of existing resources can be achieved by integrating electric vehicle (EV) charging into the energy systems of buildings. Additionally distributed energy resources (DERs), such as EVs, contribute to the decarbonization of both the power generation and transportation sectors. Multifunctional buildings—integrating residential, commercial, and service functions within a single facility—enhance energy efficiency and flexibility by redistributing consumption over time, particularly during peak hours. To realize these benefits, residential and public charging infrastructure should adopt smart EV charging and provide flexibility services that reduce energy consumption while contributing both economically and environmentally. 

The aim of this thesis is to explore how increased demand flexibility at the user level, enabled by smart charging, can create value for different stakeholders. It examines both the technical possibilities and the challenges of smart charging through a combination of simulations and real-world experiments. The research is guided by two central questions: (i) What are the technical opportunities for smart charging strategies when considering different stakeholders and real-world analyses? (ii) What benefits and challenges arise from implementing unidirectional (V1G) and bidirectional (V2G) charging strategies and flexibility services? 

These questions were primarily investigated using two testbeds: the multifunctional building Dansmästaren and the Research Twin charging station at the Ångström Laboratory in Uppsala, Sweden. The thesis presents simulation results and experimental studies that advance the understanding of V1G and V2G strategies under real-world conditions. 

The strategies developed in this work present technically feasible solutions that take different stakeholder perspectives into account. Experimental studies demonstrated economic benefits of V1G implementation from the perspective of parking facility owners. From the grid owner’s perspective, a predictive model was developed that delivered accurate results and has been integrated into the building’s Energy Management System (EMS). The user perspective was also included, providing valuable insights into EV owners’ concerns, availability, and acceptance of smart charging solutions. 

Overall, the results of this thesis show that the proposed framework, validated in real-world environments, is transferable to other facilities with similar energy system infrastructures. The long-term ambition is to scale these solutions to city-wide applications, thereby enabling large-scale deployment of smart charging strategies.
