Abstract [en]

For reasons of achieving energy security, reducing global warming and promoting the vision of a common electricity market, the European Union (EU) is transforming the EU electricity grid from a large set of independent hierarchical national grids into one meshed EU-wide grid. For the first time in the electric power industry’s history,residential consumers are being integrated into the grid as active consumers as well as micro-generators of electricity. The needs and envisioned actions of end-consumers form part of a set of EU directives targeting increased energy effciency and improved energy performance in buildings, e.g. through technical advances such as residentialdemand response programmes. To fulfil the EU energy policy, technical systems mustbe revised and extended. However, this poses a challenge for developers, since the EUdirectives are not formulated as system requirements. Another issue is whether EU en-ergy policy stipulates system capabilities that contradict development project-specific capabilities. This paper attempts to elicit and implement household demand response system capabilities from EU directives and from project-specific capabilities for the case of the Stockholm Royal Seaport urban smart grid project. We also examined whether EU energy policy capabilities are sufficiently generic to include the project-specific Stockholm Royal Seaport capabilities or whether there are major omissions and what they comprise. We found that the capabilities we extracted from the EU energy policy directives are generally applicable (with the addition of a social acceptance capability) and can be used as the foundation for development work on project-specific household demand response systems.

Abstract [en]

In order to achieve energy security, reduce global warming and promote the vision of a common electricity market, the European Union (EU) is transforming the EU electricity grid from a large set of independent hierarchical national grids into one meshed EU-wide grid. For the first time in the history of the electric power industry, residential consumers are being integrated into the grid as active consumers and micro-generators of electricity. In the near future, residential buildings in the EU will have to use much less energy and the right source of energy. If residential consumers want to maintain the same level of energy service, buildings will have to use and produce energy differently. Decentralised energy production from renewable energy sources beside or within residential buildingsis required. Distribution grids will receive more locally produced energy and be more autonomous. Suppliers and distribution system operators will have to change business models from quantity-based to service-based. As residential consumers become more active in the EU, residential system developers need to understand what and how system requirements can support EU energy policy. This thesis therefore interprets EU energy policy concerns in terms of factors influencing the residential demand response system design. To test the viability of the influencing factors, system design was constructed and prototyped. One important influencing factor,the “greenness” of electricity information, was concretised as a dynamic CO2 signal and integrated into the system design as a residential demand response signal. The dynamic CO2 signal was not always correlated with the dynamic price of electricity, but there were strong indications that the CO2 intensity signal can and should be used as a supplement to the price signal in the residential demand response system to increase motivation for energy savings. It was found that a CO2 intensity-driven Time-of-Use tariff can be developed, based on forecasts of the hourly wholesale market price and the CO2 intensity, and that this tariff is beneficial for both supplier and household. The thesis thus demonstrates that it is possible to extract system design-influencing factors from EU energy policy and use these for the design and implementation of a residential demand response system.
