The aim is to flatten consumer demand and make better use of home-based generation. The Study Group considered the mechanism of connecting batteries to the local distribution system, the ability to meet engineering requirements for the standard of the connection, and the potential impact of large numbers of such connections on stability of the local distribution network. Network and (DC-AC) invertor models were used to examine network connection transients. A statistical model was proposed to estimate the distribution of key electrical parameters to determine the likelihood of engineering standards being exceeded. The Study Group also considered stochastic methods of modelling wind speed, to better understand the requirements for battery energy storage as a complement to wind power. date: 2011 type: Study Group Report type: NonPeerReviewed format: application/pdf language: en identifier: http://miis.maths.ox.ac.uk/miis/577/1/4.pdf identifier: M., Brown and L., MacManus (2011) Effect of distributed energy systems on the electricity grid.
