Supporting sustainable mini-grid development and production of wind turbines in Kenya
|
COSTUMER:
Danida Market Development Partnerships
|
With the objective to reduce poverty and stimulate economic growth in rural Kenya, the project aims to develop a market for low-cost, partly locally produced wind turbines for rural electrification. The project will demonstrate the technical, social and economic feasibility of integrating a wind turbine into a smart solar-powered mini-grid in Kenya, and will develop this concept into a viable business for the private companies involved, having the technical, economic and management capacity to exploit it. The expected outcomes of the project are:
- local jobs in manufacturing, assembly, installation, O&M of low cost turbines in mini-grids;
- established local business for manufacturing parts of small modern wind turbines;
- and reduced cost of electricity provided by mini-grids, benefiting disadvantaged communities.
The project is the first in the Danish Government's new program "Danida Market Development Partnerships". It will bring together communities, public institutions and commercial companies.

CUSTOMER:
European Network of Transmission System Operators - Electricity
|
DTU was chosen to provide a set of synthetic synchronous wind, solar and temperatures time series obtained by mesoscale dynamical downscaling simulation with the Weather Research and Forecasting (WRF) and CorWind model.
The time series were generated for different spatial distributions for the countries members of ENTSO-E. The aggregation level ranged from country-wise to area levels, with hourly resolution.
The 12-year time series database is used in a biennial, non-binding, Ten-Year Network Development Plan (TYNDP). This network development plan is designed to increase information and transparency on investment needs in pan-European electricity transmission systems and, in doing so, support decision-makers at regional and European level.

Simulation of balancing in the Danish power system
|
CUSTOMER:
Energinet.dk
|
The increased penetration of wind power in the Danish power system also causes an increased need for balancing power. This is because the wind power forecast errors also increase with the level of penetration of wind power. Energinet.dk has developed Simba to be able to simulate and thereby quantify the balancing process in the Danish power system, with special focus on the imbalances caused by wind power forecast errors.
According to Energinet.dk, “Simba models the intra-hour balancing of the power system and is based on the Danish principles of balancing. Traditionally, modeling issues have put the main focus on calculating hourly energy values, while intra-hourly modeling attracted little attention. SimBa has closed this gap.”
Simba is intended for the following studies:
- Planning of investment
- Assessment of new market designs (e.g. towards real time)
- Assessment of cost / value of reserves
- Assessment of needs for reserve capacities
- Economic optimisation of system services
- Assessment of flexible demand support to system balancing
The main source of imbalance in the Danish power system is the wind power uncertainty. Therefore, this uncertainty is key input to Simba balancing. DTU Wind energy is partner in the Simba project, contributing mainly with CorWind simulations of consistent time series of wind power production and wind power prognoses with day-ahead and hour-ahead

Transmission system operation with large penetration of wind and other renewable electricity sources in networks
|
CUSTOMER:
European Commission – 7th Framework Programme
|
A group of 6 Transmission System Operators (Belgium, Denmark, France, Germany, The Netherlands and Spain) with 2 generator companies, 5 manufacturers and research organisations, performed 6 demonstration projects to remove several barriers which prevent the electric system from welcoming more wind electricity, and wind electricity from contributing more to the electric system.
One of the six demonstrations was the so-called Storm Demonstration lead by Energinet.dk. Off-shore wind farm shut downs under stormy conditions will be demonstrated in Denmark using one of the world largest off-shore wind farm, Horns Rev II. The wind turbine manufacturer SIEMENS Wind Power developed a new storm controller that mitigated these shut-downs, and the new controller was demonstrated and compared to the conventional controller in full 200MW wind farm scale.
The experimental results of this demonstration were integrated into European impact analyses to show the scalability of the solutions. DTU was leading the work package on upscaling and economic impact of the TWENTIES demonstrations, see eg [4]. Together with storm demonstration partners Energinet.dk, DONG Energy (wind farm owner), Siemens Wind Power (wind turbine manufacturer) and SINTEF (studying balancing with hydro power in Norway). CorWind was a key tool in this study.

Power system reliability management
|
CUSTOMER:
European Commission – 7th Framework Programme
|
Power system reliability management aims to maintain power system performance at a desired level, while minimizing the socio-economic costs of keeping the power system at that performance level.
Historically in Europe, network reliability management has been lying on the so-called “N-1” criterion: in case of fault of one relevant element (e.g. one transmission system element, one significant generation element or one significant distribution network element), the elements remaining in operation must be capable of accommodating the new operational situation without violating the network’s operational security limits.
Today, the increasing uncertainty of generation due to intermittent energy sources, combined with the opportunities provided e.g. by demand-side management and energy storage, call for imagining new reliability criteria with a better balance between reliability and costs.
The GARPUR project designs, develops, assesses and evaluates such new reliability criteria to be progressively implemented over the next decades at a pan-European level, while maximising social welfare.

A fully renewable hybrid CSP plant
|
COSTUMER:
Supported by 7th Framework Programme of the European Commission
|
Renewable energy are often criticized for not being able to produce supply power to the electrical grid in a manner that is stable, firm and reliable. This difficulty can find a proper and viable solution through hybrid CSP/biomass plants. The market is showing a strong interest in hybrid technologies for power generation. For instance; the American company eSolar (owned by General Electric) has established an alliance with the Chinese company Penglai, in order to develop CSP/biomass technology, sharing turbines and other infrastructure, reducing costs and producing energy throughout the whole day.
The aim of HYSOL Project is to become the European reference in competition to this and other initiatives ongoing in the CSP/biomass global market. The HYSOL Project focusses on overcoming the CSP technology limitations to increase its contribution in the global electric market, hybridising with biomass energy to achieve 100 % renewable and sustainable energy, and providing a stable and reliable power independently of meteorological circumstances.
GENERAL OBJECTIVE
The main added value of the hybridisation concept will be the achievement of the Europe Strategic Energy Technology plan (SET-Plan), which is the market, the industry and the European Union goal on energy matters: self-producing firm renewable energy with an optimal cost-efficiency ratio.
The present proposal focuses on the study, the design, the pre-industrial scale demonstration of around 2,5MWth and the optimisation of an innovative configuration based on a new HRS (gas-molten salt) and an AGT simulator implemented in an existing CSP plant. In addition, gas fuel used in the AGT simulator will be produced from biomass considering the environmental sustainability factor; therefore, the hybrid installation will become a full renewable plant.

The COMETS project will deliver tools to ensure energy friendly transport. New tools for analysis combine models for energy systems and transport models and will design the future of energy efficient transportation solutions. COMETS integrates the two existing decision-making and analysis tools in the transport and energy sector and will thus be the first project to bridge the gap between effective infrastructure utilization and the energy grid.
To combine the large amounts of different data and provide recommendations and solutions that are not only innovative, but also directly applicable, COMETS is based on cooperation between a broad group of researchers from DTU Management Engineering, Transport DTU, Roskilde University, University College Cork, Concito, Technology Council , Danish Energy, DEA and E4SMA (Italy).
The project contributes to a cost-effective fossil free energy and transport sector by 2050, by understanding the impact on the energy system from 1) the transport sector, 2) consumer preferences and behaviour regarding transportation, and 3) planning of cities and transport infrastructure. COMETS will:
Develop a new modelling framework that links TIMES-DK with Lands Trafik Modellen run by DTU Transport. The goal is to develop an energy system modelling framework beyond state of the art, integrating transport and energy system analyses.
Analyze the environmental and economic impacts on the future energy system from an increasingly renewable-based and system-integrated transport sector.
Produce a plan for de-carbonizing the Danish Energy System that highlights when transport and fuel infrastructure need to be developed.

Technology opportunities in nordic energy system transitions
|
COSTUMER:
The project is initiated and funded by Nordic Energy Research
|
To meet 2050 energy and climate policy goals, a major transition is required in the Nordic region. Indeed, changing energy and transport systems may require fundamental social changes. Industrial actors and policy makers will need insights and analyses to help guide their decision-making throughout this process; and, these analyses will have to take account of concerns of environmental sustainability and economic competitiveness.
The TOP-NEST project has developed an approach that addresses this challenge, by clarifying the current situation, and identifying the most promising pathways for towards more sustainable systems. The project seeks to:
- Guide industrial strategies and governments in making the transition to sustainable Nordic energy and transport systems towards 2050.
- Enhance the competitive position of Nordic industries in the international market for clean technologies.

Integrating PV in smart grids
|
COSTUMER:
Supported by Horizon2020
|
As energy demand continues to increase in an unsustainable and environmentally damaging way, a worldwide need arises for advancement of renewable energy technologies. At the same time the developing world is reaching a critical pivotal point for high penetration of renewables in the national grid which is expected to result in severe operational problems unless restructuring of the current, traditional grid takes place. Thus the research field chosen to be enhanced in this project, namely photovoltaic (PV) and integration in smart grids, has a timely and significant importance of global dimensions, particularly so for regions of high solar insolation such as the MENA region.
The concept underpinning the project foresees the strengthening of a research field in an academic institution of a low performer country through linking effectively with internationally-leading research partners in the specific field. In particular, the PVlab of UCY will twin with AIT and DTU in order to enhance its research and innovation capabilities in PV and grid integration in smart grids. The specific topic has been selected based on the excellent track record and fully-operating state-of-the-art infrastructure in solar energy and PV technology research at UCY developed since 2005.

System validation approaches for Smart Grids
|
COSTUMER:
Supported by H2020
|
Renewable energy sources are key enablers to decrease greenhouse gas emissions. The intermittent behaviour of most renewable energy sources and their limited storage capabilities present new challenges to power system operators in maintaining power quality and reliability. However, the increased availability of advanced automation and communication technologies has also provided new intelligent solutions to these challenges. Previous work has presented various new methods to operate highly interconnected power grids with corresponding components in a more effective way. As a consequence of these developments the traditional power system is transformed into a cyber-physical system, a Smart Grid. Previous and ongoing research activities have mainly focused on validating certain aspects of Smart Grids, but until now no integrated approach for analysing and evaluating complex configurations in a cyber-physical systems manner is available.
The lack of system validation approaches for Smart Grids is especially addressed by ERIGrid. By providing a Pan-European research infrastructure ERIGrid supports technological development as well as the roll out of Smart Grid solutions and concepts in Europe. It uses a holistic, cyber-physical systems based approach by integrating 18 European research centres and institutions with outstanding research infrastructures and jointly develops common methods, concepts, and procedures. ERIGrid also integrates and enhances the necessary research services for analysing, validating and testing Smart Grid configurations. System level support and education for industrial and academic researchers is also provided to foster future innovation.
