How does the network facilitate market trade? Rudi Hakvoort
Learning objectives • To understand the role of the electricity network • To introduce the different voltage levels • To explain the distribution grid and transmission grid
Electricity network Secondary 10 kV Step-up Transformer Step-down Transmission Transformer (above 100 kV) Businesses and households (240 V and 380 V)
Operators The transmission operator for the transport of electricity The system operator manages system and frequency stability The market operator is responsible for matching supply and demand
Transmission network Transmission Distribution Consumer Generation • High voltages, between 220kV and 1000kV • Alternating current (overhead) or high-voltage direct current (cables) • Run by transmission system operator (TSO) • ENTSO-E sets market rules for operating the network
