Electricity generation and electricity grids are facing an important challenge. On the one hand, scarce fossil resources as well as CO2 emission targets mean that an increasing share of energy generation must come from renewable energy sources (RES). On the other hand, the largely decentralised and highly intermittent electricity generated by RES changes the traditional patterns of energy consumption and generation. To meet increasing energy demand, grid operation must be stable and efficient. The expansion of RES requires new means of load management. Whereas conventional energy fuels can be converted whenever needed, RES cannot. Wind and solar power generation depend on external conditions and their supply is not directly controllable. Demand Response (DR) aims at adjusting the electricity demand to the grid requirements at a given point of time. It is an important pillar in the context of Smart Grid concepts for achieving the EUís 20/20/20 goals.
- The lack of the active participation of the Electricity Demand in the generation-supply process has resulted in inefficient electricity markets
- The customers have been traditionally considered as inflexible, passive and low concerned actor in the energy business
- Changes are happening worldwide as result of higher environmental concern:
- More custom-tailored energy solutions (Distributed Energy resources)
- Enhancement of customer reaction to electricity prices and contracts
- New opportunities open for flexible industrial facilities
Demand Response helps to improve the performance of electricity systems. HOWEVER Ö
