Impacts of demand response from buildings and centralized thermal energy storage on district heating systems

Demand Response and Energy Storage for Zero Energy Residential Buildings

The EU climate and energy targets and the decreasing costs have been leading to a growing utilization of solar photovoltaic generation in residential buildings. However, even in buildings with the same level of yearly generation and consumption the mismatch between the demand and the photovoltaic generation profiles leads to high power flows between the household and the grid, which is an ineff...

Heat storages in Swedish district heating systems An analysis of the installed thermal energy storage capacity

District Heating in Buildings

This paper is published by Euroheat & Power. Our aim is to inform about district heating and cooling as efficient and environmentally benign energy solutions that make use of resources that otherwise would be wasted, delivering reliable and comfortable heating and cooling in return.

The use of distributed thermal storage in district heating grids for demand side management

The work presented in this paper relates to a small scale district heating network heated by a gas fired CHP. In most common situations, such a CHP is heat driven operated, meaning that the CHP will switch on whenever heat is needed, while not taking into account the demand of electricity at that time. In this paper however, an active control strategy is developed, aiming to maximize the profit...

Thermal Transients in District Heating Systems

Heat fluxes in a district heating pipeline systems need to be controlled on the scale from minutes to an hour to adjust to evolving demand. There are two principal ways to control the heat flux keep temperature fixed but adjust velocity of the carrier (typically water) or keep the velocity flow steady but then adjust temperature at the heat producing source (heat plant). We study the latter sce...
