This article describes operation times of home appliances and energy consumption based electrical energy storage dimensioning analyses for residential areas. The analysis is based on an object in Estonia. The electrical energy storage dimensioning for consumption scheduling in the two-tariff system and on the basis of the Nord Pool Spot (NPS) price is discussed. Additionally, in the storage dimensioning part, consumption balancing using of electrical energy storage and water heater consumption shifting is analyzed. Optimization of electrical energy storage charging/discharging cycles according to realtime dynamic prices is an important topic for further research.
