Zeven projecten op het gebied van duurzame energiesystemen gehonoreerd

21 maart 2016

In de eerste ronde van het programma ESI-pose (Energiesysteemintegratie - planning, operations, en sociale inbedding) hebben NWO Exacte Wetenschappen en NWO Maatschappij- en Gedragswetenschappen zeven projecten toegekend. De verschillende onderzoeken zullen zich richten op het ontwikkelen van een nieuw duurzaam energiesysteem, waarbij elektriciteit, gas en koude/warmte in samenhang worden bekeken.

Voorstellen konden worden ingediend in twee compartimenten: één voor onderzoek in de bètawetenschappen en één voor multidisciplinair onderzoek in de bèta- en sociale wetenschappen.  Er was ca. 3,5 miljoen euro beschikbaar (waarvan 10% afkomstig van publieke/private partners) voor het aanstellen van onderzoekers aan Nederlandse kennisinstellingen. Het programma valt onder het NWO-werkprogramma voor de Topsector Energie.

Hieronder de toegekende projecten in Compartiment 1 (bètawetenschappen):

Hierarchical and distributed optimal control of integrated energy systems
Dr. ir. M.K. Camlibel, Rijksuniversiteit Groningen
For decades the main goal of the power system was to deliver power from generation plants to consumers through an extensive high-voltage transmission system and a medium to low voltage distribution system. As such the existing power system was designed in a centralized tree like fashion in order to connect a relatively small number of large plants to a large number of consumers. In addition, the gas infrastructure is developed separately, with an infrastructure consisting of high, medium and low pressure pipelines, more or less similar to the power grid structure. Both grids are regulated separately, even though they are coupled. In the future, the embedding of many more micro-CHP systems in households is foreseen, and storage of surplus electricity in the form of power-to-gas (hydrogen) is also foreseen. Within this research proposal we aim at developing new/tailored methods that integrate hierarchical and distributed optimal control methods for large-scale networked systems necessary for the embedding of new energy systems in the coupled power and gas grids.

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.
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.

System Integration of Micro-Grids through Profile Steering
Prof. dr. ir. G.J.M. Smit, Universiteit Twente
In this project we plan to develop optimisation algorithms for micro-grids based on profiles (energy demand/supply patterns over time), thereby using all forms of energy (electricity, gas, heat, ..). Profiles of local assets (e.g. CHPs, storages, controllable appliances, or converters) are steered taking into account the objectives, (comfort) constraints and restrictions of the micro-grid with the goal to achieve a resulting overall energy profile of the micro-grid that is 'friendly' for the main utility grid. By integrating forecasting and planning methods, it is possible to predict and manipulate the profile of a micro-grid for the coming time period. Moreover, through a coordinated steering of different micro-grids, peaks or shortages of energy can be reduced or avoided in the transport grid.

Optimising Flexible Energy Use in Industry
Dr. M.M. de Weerdt, Technische Universiteit 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.

Incentives and algorithms for efficient, reliable, sustainable and socially acceptable energy system integration
Prof. dr. E.M. Steg, Rijksuniversiteit Groningen
We examine how to synergise and couple infrastructure for gas and electricity and take into account heat demand, via e.g., Combined Heat Power (CHP) systems, hybrid heat pumps, Power-to-Gas and 'Gas-to-Power (fuel cells)' facilities, and develop control algorithms that enhance the efficiency, stability and sustainability of such integrated energy systems. Next, we examine which financial and social end-user incentives are acceptable and effective to match energy demand to the local fluctuating supply of various renewable energy sources to efficiently use the local capacity of the grid. We integrate incentives in the algorithms aimed to control ESI. We employ a multi-method approach, including questionnaire and experimental studies, and robust distributed control methods. We integrate macro perspectives (grid management) and micro perspectives (user behaviour and incentives; user acceptability), and study technological and social innovations in an integrated way, which is highly novel to the field yet key to develop innovative sustainable and acceptable ESI.

Regional Energy Self-Sufficiency
Prof. dr. ir. C. Vuik, Technische Universiteit Delft
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. 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.

Study and development of an energy management system and user interface that can match supply and demand of various energy carriers using user preferences while contributing to user acceptability and proper adoption of the system
Dr. K.E. Keizer, Rijksuniversiteit Groningen
In the proposed research we will design an automated energy management system with user interface that can match supply and demand of various energy sources and carriers, according to the preferences of the user. We will investigate to what extent decisions should be automatized or left under control of the users. More precisely we will study the number and type of decisions should be left to the user, and the type feedback and how to present this to the user to insure user acceptability and adoption of the systems, and support or even strengthen energy and other pro-environmental goals by users. Most important we propose to study this in a field context, with actual energy data, and users of a number of buildings provided by one of the partners.
