Electricity storage for distributed generation in the built environment

Some of the sources of distributed electricity generation in the built environment with a high potential for application cannot be scheduled: for example, solar and some forms of combined heat and power generation. One of the mechanisms to allow a substantial contribution of these intermittent electricity sources in future grids is electricity storage. We have evaluated a number of business cases for financially beneficial operation of electricity storage in case of small users in the built environment. Financially most attractive is the case in which generated electricity is stored for own use at a later time. A storage system has been built, which will be used to validate these theoretical findings and to compare actual benefits of the different approaches to energy management
