NWO grand for three energy projects TU Delft
In the first round of the program ESI pose (Energy System - planning, operations, and social embeddedness) NWO Physical Sciences and NWO Social Sciences have awarded seven projects with three of the TU Delft.
Heat and Power Systems at Industrial Sites and Harbours
Prof. dr. ir. J.A. la Poutré, Centrum Wiskunde & Informatica
Our energy system is transforming into a sustainable system. Especially important for potential innovations are the use of energy types electricity and heat. This is amongst others due to the increasing role of electricity, and because heat often is a large side product (waste) as well as one of the important reasons for energy demand.
Industrial sites (with multiple actors) and harbors are important locations for the consumption and production of energy. Also here, the different roles of electricity and heat can be distinguished, however with a higher intensity per actor than in domestic environments and thus with a higher impact on the intensity of dynamics in the energy demand, supply, and locational aspects at the site. Whereas in domestic areas, energy demand and supply can potentially be peak-shaved by e.g. using incentive mechanisms like dynamic pricing and by averaging over many actors, this only holds into a limited extent for industrial sites and harbors, with big actors and strict, large demand or supply of energy for various steps in industrial processes. Electricity and heat both play an important role in industrial sites and harbors, especially for future sustainability. The project aims at developing solutions for automated power and heat management at industrial sites and harbors with a combination of multiple actors, industrial processes, and external factors. This is carried out by developing innovative models, simulation systems, agent-based market and coordination mechanisms, and optimization techniques.
Optimising Flexible Energy Use in Industry
Dr. M.M. de Weerdt, TU Delft
A large part of renewably generated power is intermittent, uncertain, and uncontrollable. As balance between demand and generation is required at all times, flexibility in electricity demand is needed to prevent having significant costly flexible controllable generation (from fossil energy sources) on stand-by. Research and even some first pilot studies have been performed to use flexibility of heating, cooling, and (electrical vehicle) charging in households. However, industry in the Netherlands, using about three times more energy than households [CBS, 2013], offers far more promising opportunities by considering flexibility from all used carriers of energy.
The problem is that unleashing this potential of energy flexibility in industry (switching between energy carriers, using and sharing buffers for heat, steam, intermediate products, varying production, etc.) requires optimising the daily operations not just regarding throughput, but also to include making cost-effective energy trading decisions. We will develop algorithmic techniques to support both these decision problems under uncertainty.
Stakeholders are operators and business analysts of large industrial plants such as the chemical industry in the Port of Rotterdam, but also policy makers, utility companies, and port authorities to explore and enable better infrastructures and new business opportunities.
Compartiment 2 (bèta-gamma):
Regional Energy Self-Sufficiency
Prof. dr. ir. C. Vuik, TU Delft
Local communities increasingly take an active role in the transition to more sustainable and autonomous local energy supply systems, using local energy sources like wind, solar, and biomass. However, this sustainable local energy supply is associated with high fluctuations and uncertainty caused by the intermittency of wind and solar power. To guarantee high reliability of energy supply on the consumer side while being cost effective, increased system integration and flexibility, local energy storage and retrieval, and combining energy forms are called for.
Given the local energy infrastructure of gas, power and heat, and typical local energy demand patterns this research project investigates how an optimal local energy supply system can be designed such that local energy targets can be realized with minimum dependence on the national energy grids. This is not only a technical problem, but also a question of how these local energy systems should be regulated and operated Hence, next to an optimal technical design also an institutional design of local energy systems needs to be developed that addresses its regulation and governance. This requires model and methodology development in two areas. In the first area the focus is on the optimal overall design of the energy supply system and the corresponding required institutions. The research here is on distributed optimization with various investment decisions made by different actors. In the second area the focus is on the simulation and optimization of gas, power and heat flow in their combined networks, for assessing solution uncertainty, sensitivity, and reliability.
Proposals could be submitted in to compartments: one for research in bèta science and one for multidisciplinary research bèta- and social sciences. About 3,5 million euro was available for the appointment of researchers at the Dutch knowledge institutes. The research will target the development of new sustainable energy systems, where the synergy between electricity, gas and cold/warmth will be examined. The program is part of a NWO-werkprogramma for the Topsector Energie.
