Demand Side Management in Private Households – Actual Potential, Future Potential, Restrictions

Demand Side Management (DSM) is one way to keep the balance between energy generation and energy consumption and is therefore important in grids with fluctuating renewable energy sources. To explore how typical households with their specific electricity consumptions are able to take part at DSM the DSM potentials were calculated. First the DSM potentials for the single types of load in households that are practical were calculated as actual potential with actual types of appliances. Then they were calculated as future DSM potential with today’s high efficient appliances that will have replaced the actual types in households in the future. The future potential considers also expected changes like less distribution of storage heaters and much higher distributions of heat pumps and electric vehicles. Restrictions in case of DSM are considered as well because they reduce the theoretical DSM potential remarkable. Finally the financial benefits through DSM for a typical household with four persons were calculated on base of a tariff with four different prices.
