DHI leads DSS development to help Uganda improve hydropower generatio

To optimise hydropower production, the Uganda government, through the Uganda Electricity Generation Company Limited, has implemented a DHI-led decision-support system (DSS) to forecast water flow to Lake Victoria and in the River Nile.Hydropower dams play a pivotal role in harnessing renewable energy from flowing water. The construction and operation of these dams can also impact flooding – a significant challenge worldwide, including in Uganda.
 
In a partnership with French engineering company ISL Ingénierie, DHI led the modelling work and the DSS development for the project, with the support of French development agency, Agence Française de Développement. This project was part of the EU-funded Digital Energy Facility programme, which supports innovative solutions for the energy sector.
 
DHI, in partnership with ISL, contributed to the following:
 

Initiating data collection and organising site visits to four key hydropower plants along River Nile
Collecting, reviewing and analysing data such as supplementary global datasets from earth observation products, as well as near real-time information on current conditions
Developing a water balance and allocation model for short-term and seasonal forecasts using MIKE HYDRO Basin. A flood model was used to simulate the hydrology and hydrodynamic conditions downstream of the outlet of Lake Victoria. These models were complemented by a reservoir hydropower operation model and a hydropower energy optimisation model built using ISL Ingénierie’s software.
Integrating the models into a fully operational DSS using DHI’s platform to visualise and disseminate results of the flood and flow forecasting as well as the power production. The DSS, based on MIKE OPERATIONS technology, enables automatic download and processing of earth observation and numerical weather prediction data to provide real-time, forecast and climate change scenario results to improve decision-making.
Carrying out training sessions and workshops to ensure successful knowledge transfer and sustainability of the technology

 
Bertrand Richaud, project manager from DHI, says, ‘The DSS takes into account various hydrological factors such as rainfall and evaporation, and can forecast water flow patterns up to nine months in advance considering the uncertainty of such forecast. The adoption of this technology by key stakeholders in Uganda would help the decision-making process. By using science-based tools, water shortages and flooding risks can be reduced, eventually contributing to improved hydropower production in the region.’

DHI uses digital twin for innovative rainwater management project in Bydgoszcz, Poland

In July 2023, DHI began work for the Polish utility in Bydgoszcz on an innovative project to manage rainwater more effectively.
 
DHI Poland, together with DHI Sweden, is implementing the System for Intelligent Control of Retention Reservoirs (SIS-RZ), as part of the contract 'Intelligent System for Water and Sewage System Management'.
 
The goal is to support decision-making processes related to the operation of the reservoir retention system in the Bydgoszcz area based on data provided by measurement systems, which will then be processed by artificial intelligence. The team will implement Future City Flow, DHI’s web-based decision support system and digital twin that will help Bydgoszcz Utility improve the efficiency of water resources management.
 
DHI has completed the pre-implementation analysis and has developed a concept for the construction of the SIS-RZ System. This is after considering selected methods and artificial intelligence techniques for the prediction and control of retention storage tanks, and integration with the client's infrastructure and IT architecture as well as with weather data sources.
 
A rainwater drainage MIKE+ model has been created for pilot areas, and the configuration of the initial system version has commenced, with an expected completion date by the end of December. Preparatory work for the installation of data transmission devices from retention storage tanks (telemetric modules) is in progress. The plan for the upcoming year is to develop two system versions in which it will be possible to control all 35 planned retention storage tanks.
 
Waldemar Mlaś, DHI’s Vice President for Water Supply &amp; Urban Drainage in Central and Southern Europe says, ‘Managing water and sewerage management systems can be a challenge in the changing climate. Using the power of a digital twin, Bydgoszcz Utility will be able to better execute weather-adapted control strategies to mitigate the effects of increased rainfall on infrastructure. Together with our colleagues in Sweden, we are looking forward to supporting Bydgoszcz Utility in bringing long-term benefits to residents and the environment.’

Visit from the Chinese Vice Minister of Water Resources

On Friday 10 November, the Chinese Vice Minister of Water Resources, H.E. Mr Wang Daoxi, visited DHI headquarters to learn more about digital twins and groundwater modelling.
 
The Chinese Vice Minister met with Mette Vestergaard and Zhou Chi, Managing Director of DHI China, as well as several DHI experts. The minister and his delegation were interested in learning more about how DHI enables a sustainable future for water with our digital solutions. The minister talked about his previous visit at DHI almost 20 years ago and his interest in engaging the public in efforts for sustainable water management.
 
The Chinese delegation was particularly interested in groundwater modelling and digital twins. They wanted to hear more about the technological aspects of Danish water management, and DHI is an important player in this area.
 
After the presentation, our guests received a tour of our test facilities where Karsten Lindegaard Jensen, Director of Offshore Structures, explained about our physical scale model tests and the type of major infrastructure projects we support with our world-leading facilities.
 
‘DHI has been growing and developing in China for almost 20 years, contributing professional knowledge and technology to the development of China's water and environment. During this ministerial visit, we fully demonstrated our professional ability and core technical strength as an internationally renowned water consulting company. In the future, DHI will continue to serve China's water and environment and contribute to China's scientific and technological development,’ states Zou Chi.
 
Denmark and China have strategic collaborations on groundwater management and wastewater management. DHI took part in a Danish Environmental Protection Agency’s delegation accompanying the Danish Minister of the Environment, Magnus Heunicke, on a trip to China in September, where DHI presented one of the demonstration projects. The visit from the Chinese Vice Minister at DHI is part of strengthening the green cooperation between Denmark and China.

Tomorrow’s floating wind turbines to be tested at DHI

A consortium of leading Danish players will establish a test lab for floating wind turbines in the 20-MW class. This test lab will be located at DHI and will include wind, waves and a model-scale wind turbine. The measurements will be connected directly to calculation models in a 'Digital Twin' setup. Innovation Fund Denmark invests DKK 15.3 million in the project.
 
92% of Europe's offshore wind turbines have been produced with origin in the Danish wind industry. The next step is floating wind farms, where new projects up to 2030 are predicted to reach about half of the current installed bottom fixed capacity.
 
The floating foundations must be able to withstand extreme waves and storms, and their costs must be brought down. This places new demands on calculation models for both turbines and foundations. This is precisely where the new FloatLab project contributes to uncovering the new physics, reducing risks and validating the engineering models used for turbine and floating foundation design.
 
‘FloatLab will change the way we combine numerical models and measurement data,’ says Henrik Bredmose, Professor at DTU and leader of the project and continues: ‘We establish a direct link between the measurement setup and the calculation models, so that we can ultimately make the design process faster and more accurate.’
 
The laboratory will be located at DHI, where a new wind generator and a new model scale wind turbine will be built to be mounted on models of new floating foundations. The project partners are DTU, DHI, Siemens-Gamesa Renewable Energy, Stiesdal Offshore, Stromning and Ørsted, all of which draw on solid experience from floating turbines and offshore wind. Among the aspects to be tested during the project are 3D waves, loads from breaking waves, turbulence and failure of mooring lines.
 
‘Floating offshore wind turbines are still a relatively new technology, and production and processes are still not optimised. With FloatLab, we will increase the industry knowledge and can eventually reduce risks and costs for offshore wind entrepreneurs and thereby accelerate the green transition’, says Pietro Danilo Tomaselli, Senior Hydraulic Engineer and head of the FloatLab activities at DHI.
 
Stiesdal Offshore, developer of the innovative Tetra floating foundation concept, is another project partner. ‘We are excited to contribute our expertise on the Tetra foundation and provide insights into the unique challenges regarding industrialisation faced by the floating wind industry. We eagerly anticipate our involvement in the project,’ states Michael Borg, Chief Engineer at Stiesdal Offshore.
 
The project, which Innovation Fund Denmark invests DKK 15.3 million in, will run until 2027 with gradual upgrading of measurement setup, models and interconnections. The results will be presented at open workshops, conferences, a PhD summer school and will be included in the numerical calculation models.
