Software agent-based strategies using micro-economic theory like PowerMatcher[1] have been utilized to coordinate demand and supply matching for electricity. Virtual power plants (VPPs) using these strategies have been tested in living lab environments on a scale of up to hundreds of households. So far, the coordination configuration of a VPP is...

The increasing introduction of district heating systems together with hybrid energy appliances as heat pumps and micro-combined heat and power installations, results in new opportunities for optimizing the available resources in multi-commodity smart energy systems, including electricity, heat and gas. By 'converting' forms of energy using...

We estimate the rebound effect for residential space heating at the EU-27 level, which occurs when an improvement in energy efficiency results in additional energy consumption. Three types of rebound effects are distinguished, namely the direct effect, indirect effect and the embodied energy. We demonstrate that the magnitude of the direct...

For the built environment it is envisaged that in the near future the total annual heat demand could be covered by renewable sources generated within the built environment. More and more devices, such as heat pumps and solar collectors will enable a sustainable and distributed generation of heat. Centralized climate management systems are...

In the near future an increase of both thermal grids and sustainable suppliers of heat with intermittency behavior, connected to these heat grids, is expected. For smart operation this challenges the current centralized management systems. To deal with this and to optimize cost and energy efficiency a multi-agent approach is proposed, which to a...

PowerMatching City (see ref. (Bliek et al., 2010)) is a living lab smart grid demonstration that shows the feasibility of a market based smart grid optimization methodology. It allows simultaneous optimization of multiple goals of the various stakeholders in a smart grid: in-home optimization, commercial optimization (VPP operation), congestion...

One of the challenges of the near future for a more renewable Dutch electricity infrastructure is the embedding of high concentrations of heat pumps in currently built domestic residences. In the Dutch situation demand of electricity occurs simultaneously with demand of heat, high electricity peak loads in the low voltage network are expected....

Dutch government and greenhouse horticultural practice aim for strongly reduced fossil energy use and of environmental loads in 2010 and energy neutral greenhouses in 2020. This research aims to design a greenhouse concept with minimal use of fossil energy and independent of nearby greenhouses. The concept is called the zero-fossil-energy...

Recently small-scale thermally driven chillers have gained a lot of interest because their potential to save primary energy, to reduce electricity peaks on the grids and to improve cost benefit ratio of micro-CHP units when combined into tri-generation systems. ECN has developed a small-scale (output < 5 kW) silicagel-water adsoprtion chiller...

The formation as well as the decomposition of magnesium chloride ammonia complexes was studied by high-pressure differential scanning calorimetry (HPDSC) and thermogravimetric analysis (TG). HPDSC runs were performed under constant ammonia pressure conditions to determine the transition temperatures and stability regions of the ammonia complexes...

In this report, the simulation results for the energy system of a districtcontaining 1300 houses is presented. The starting points for these calculations are the electricity and heating demand patterns based on the 'city of the sun', a planned residential area in Heerhugowaard, the Netherlands. The main focus is concentrated on the possibility...

Non-0O2 Greenhouse gases, in particular CFCs, HCFCs and HFCs, are the main refrigerants used in refrigeration, air conditioning and heat pump equipment. This kind of equipment traditionally leaks significantly (10 to 40 % of the content on a yearly base) during operational life. At end of life, the refrigerant content traditionally emits...
