Optimization of a battery energy storage system : For utilization of peak shaving and fast frequency reserve

University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

Abstract: As Sweden switches to increasing renewable electricity production the demand on the energy grid and energy market will become higher. Since a bigger part of the electricity consumption will come from flowing energy sources the production will become less stable and harder to plan with the consumption. The inertia of the electrical system will also decrease since solar and wind power are not synchronously connected to the electrical system which will make the system more sensitive to interference. In order to keep the short-term balance so that the frequency remains at 50
