Smart charging protocols for electric vehicles can help avoid overload and instability in the electrical distribution network and can increase the proportion of locally generated solar energy used for charging. Our results show that the impact of smart charging depends heavily on the technical charging characteristics of the target vehicle.

The application of DC grids is gaining more attention in office applications. Especially since powering an office desk would not require a high power connection to the main AC grid but could be made sustainable using solar power and battery storage. This would result in fewer converters and further advanced grid utilization. In this paper, a sustainable desk power application is described that can be used for powering typical office appliances such as computers, lighting, and telephones. The desk will be powered by a solar panel and has a battery for energy storage. The applied DC grid includes droop control for power management and can either operate stand-alone or connected to other DC-desks to create a meshed-grid system. A dynamic DC nano-grid is made using multiple self-developed half-bridge circuit boards controlled by microcontrollers. This grid is monitored and controlled using a lightweight network protocol, allowing for online integration. Droop control is used to create dynamic power management, allowing automated control for power consumption and production. Digital control is used to regulate the power flow, and drive other applications, including batteries and solar panels. The practical demonstrative setup is a small-sized desktop with applications built into it, such as a lamp, wireless charging pad, and laptop charge point for devices up to 45W. User control is added in the form of an interactive remote wireless touch panel and power consumption is monitored and stored in the cloud. The paper includes a description of technical implementation as well as power consumption measurements.
The Netherlands is facinggreat challenges to achieve (inter)national climate mitigation objectives inlimited time, budget and space. Drastic innovative measures such as floatingsolar parks are high on political agendas and are entering our water systems.The clear advantages of floating solar (multifunctional use of space) led to afast deployment of renewable energy sources without extensive research toadequately evaluate the impacts on our environment. Acquisition ofresearch data with holistic monitoring methods are urgently needed in order toprevent disinvestments.In this project 10 SMEs with different expertiseand technologies are joining efforts with researchers and four public parties(and 12 indirectly involved) to answer the research question “Which monitoringtechnologies and intelligent data interpretation techniques are requiredto be able to conduct comprehensive, efficient and cost effective monitoring ofthe impacts of floating solar panels in their surroundings?"The outputs after a two-yearproject will play a significant and indispensable role in making Green EnergyResources Greener. Specific output includes a detailed inventory of existingprojects, monitoring method for collection/analysis of datasets(parameters/footage on climate, water quality, ecology) on the effects offloating solar panels on the environment using heterogeneous unmanned robots,workshops with public & private partners and stakeholders,scientific and technical papers and update of national guidelines for optimizingthe relationship between solar panels and the surrounding environment. Projectresults have a global interest and the consortium partners aim at upscaling forthe international market. This project will enrich the involved partners withtheir practical knowledge, and SMEs will be equipped with the new technologiesto be at the forefront and benefit from the increasing floating solar marketopportunities.

The Netherlands is facing great challenges to achieve (inter)national climate mitigation objectives in limited time, budget and space. Drastic innovative measures such as floating solar parks are high on political agendas and are entering our water systems . The clear advantages of floating solar (multifunctional use of space) led to a fast deployment of renewable energy sources without extensive research to adequately evaluate the impacts on our environment. Acquisition of research data with holistic monitoring methods are urgently needed in order to prevent disinvestments. In this proposal ten SMEs with different expertise and technologies are joining efforts with researchers and four public parties (and 12 indirectly involved) to answer the research question “Which monitoring technologies and intelligent data interpretation techniques are required to be able to conduct comprehensive, efficient and cost-effective monitoring of the impacts of floating solar panels in their surroundings?"

Zuyd University and partners will develop novel coatings that contribute to a reduction in energy consumption of houses and buildings. The built environment currently consumes 46% of all energy, mainly for heating and cooling. A strong reduction is required as part of the transition towards sustainable energy. This is expressed by ambitious targets set by the Parkstad region, which has set itself the target to be energy neutral in 2040. For the Window of the Future Zuyd University (lectoraat Nanostructured Materials) and DWI (post-doc) aims to develop infrared regulating coatings that keep the heat inside in winter and outside in summer. These coatings are expected to strongly contribute to reduction of energy consumption. We will develop coating materials for application on glass windows, which are transparent for visible light to allow maximal daylight entering the building, and simultaneously regulate the transmission and reflection of IR heat. Kriya and Physee (SMEs) will advise Zuyd on technical and economic challenges related to the development of IR regulating glass windows. OMT Solutions (SME) and SGS Intron will advise on characterization and the performance validation. The need for such windows is confirmed by TNO/The Brightlands Materials Center as central challenge in their Optoelectronics program. They contribute largely to this project. Large demonstrator windows will be coated, and installed in test houses for real-life testing and quantification of the energy reduction. Zuyd (lectoraat Solar Energy in the Built Environment) will quantify the impact of smart IR regulating windows on the energy transition by comparing their impact to other available technologies, e.g. solar cells. In this quantification, Zuyd will focus on the Parkstad region. Together with Parkstad and Maastricht University (Ph.D. student), Zuyd will also quantify the socio-economic impact, and promote the societal acceptance of smart IR regulating windows.
