In the weeks lea P7 INTRODUCTION TO 4ghd-PROJECTS By Brian Vad Mathiesen, Professor, Aalborg University At the 2nd International Conference on Smart Energy Systems and 4th Generation District Heating we gathered in a venue that is an old power plant. Here at Nordkraft, both oil and coal have been the source of ele P8 TOWARDS REALISTIC PRODUCTION PLANNING By Magnus Dahl, industrial PhD fellow at AffaldVarme Aarhus and Aarhus University It is possible to ensure security of supply while reducing economic risk. District heating production planners who are aware of the changing uncertainty in their forecasts mak P9 heating network means reducing the amount of heat that is lost to the ground. Heat losses up to 20% of the total produced heat are common in district heating networks, and there is a substantial economic and environmental potential in reducing heat losses. With computer simulations, I have demon P10 DEVELOPMENT OF THE UK HEAT INTERFACE UNIT (HIU) TESTING REGIME By Martin Crane, owner and managing director, Carbon Alternatives From a low base of only a few percent of households being on district heating (DH), the UK is now developing more DH. In some areas, such as London, it is a requirem P11 The Test Procedure includes a test which is conducted with radiators without flow control to clearly demonstrate the impacts. This also demonstrates the importance of correct commissioning of the substation and the secondary heating systems.

In a normal situation, wind production is only curtailed in hours with low spot prices and DHCP CHP only produces in hours with high spot prices, w P15 SYSTEM INTEGRATION By Lars Gullev, Managing Director, VEKS A FAIRY TALE OF 100% EFFICIENT USE OF RESOURCES - THE LIFE CYCLE OF A CITRUS FRUIT FROM SOUTH AMERICA TO DENMARK For all of us, efficient use of the resources in the world is on top of the agenda. Only in this way can we ensure that o P16 The project could make it possible to produce biogas and utilize the biogas for producing combined heat and power (CHP), which is in line with both the national policy of promoting CHP and biogas, and the energy and climate policy objectives of the municipality of Solroed to convert the local h P17 De-gassed biomass a natural fertilizer When the biomass - including citrus peels - is de-gassed, the liquid fraction is delivered back to the farmers where it is used as a natural fertilizer on fields.

Fluctuating wind and solar energy (PV) calls for energy storage. Electric batt P19 Operating a smart energy system As renewable and efficient energy is of low quality and fluctuating, tariffs and contracts should take into account time and quality as well as the cost structure. DH tariffs should reflect that. Smart electric grid tariffs should also encourage smart electricity P20 The baseline for assessing the DH&C solution in the city district will be individual heat pumps for heating and individual chillers for cooling. In the table below, we see the main data of the DH&C system with ATES, heat and cold water storage tanks and a heat pump for co-generation of heat and P21 SYSTEM INTEGRATION COORDINATION ON ALL LEVELS SYSTEM INTEGRATION By Anders Hasselager, Project Manager, GATE21 The Danish energy system is well defined but its not always well coordinated.

This backbone network (designed for a temperature regime of 28/16C) provides heat and cold to the cluster networks (see figure 1), to which all buildings are connected. The ambition is to make these clusters more energy self-sufficient by maximising the P25 consumption in comparison to the real energy consumption. As can be seen, the forecaster has a mean absolute percentage error of about 8% during the tested period. This is considered as good for these model-free algorithms.
