Organization and Control of A local Market Based Concept towards Onsite Distributed Energy Resource Based Electricity Supply in Urban Swedish Residential Buildings

Abstract: The concept of ‘prosumers’: of promoting consumers of electricity with a joint generation role has led to an unprecedented increase in attention for exploring distributed generation from a systems perspective. Amongst these, households occupy a significant proportion of the end use electricity consumption in most developed countries.  Widespread adoption of onsite distributed generation providing households with their electricity demand could thus make them very significant actors in terms of their aggregated impact on the wider electricity power system.   With a high level of general public perception and support for environmentally benign products including ‘green’ electricity, and a pioneering, liberalized electricity market: Sweden offers an ideal opportunity for innovation addressing more active roles played by households for influencing the source of their end- use electricity source and moreover, in wider adoption of renewable energy in our everyday lives.   Incorporated as a research contribution for a proof-of-concept for the Stockholm Royal Seaport Project, this Master thesis effort addresses the organization and functioning of an onsite distributed energy resources based electricity supply for Swedish residential apartment buildings.   Taking inspiration from existing community ownership renewable energy models and existing research in integrating distributed energy resources, an outline of a business model is presented which is built around features characteristic of the Swedish residential system. It provides for a local market based system for trading of excess/ deficit of electricity amongst neighbors and offers an means to create a setup which provides space for new developments, while at the same time ensuring the integrity of the ownership and control which a household consumer can exert.   The thesis effort focused on development of the concept and an initial implementation of the control aspect facilitating the trading of electrical energy between households in a twenty- five apartment residential building, during each hour of a year.
