Energy flexibility of a Czech smart home (4/4)

To conclude our series on using flexibility in the smart home, we look at practical model examples of smart home operation. This time, we focus primarily on the potential to make operating a smart home more economical.  A smart family home heated by an air-to-water heat pump, equipped with a mechanical ventilation system, an unheated swimming pool and standard household appliances will serve as our model case.

The modelling will first demonstrate the economic benefit of installing a PV system with battery storage, based on a set electricity supply tariff. The second step will model the optimal use of battery storage flexibility in relation to consumption, PV generation and spot electricity prices.

For the model home, measured hourly consumption data for 2022 is available, and measured irradiance data from a local weather station is used to simulate PV generation. Electricity spot prices are sourced from OTE. Total electricity consumption in 2022 was 12,4 MWh. The assumed PV installation has a capacity of 10kWp and is supplemented by battery storage with a capacity of 15kWh.
