Examples: Virtual power plant Smooth integration of distributed resources into operation ABB s offering Characteristics and benefits Optimax PowerFit Symphony Plus Network Manager SCADA/GMS Participation of small- and medium-sized power generation units in the electricity market to attain maximized results Provision of grid services such as frequency regulation through shortterm balancing of supply and demand Optimized power supply by centralized control of assets: conventional and renewables generation units, power storage devices and flexible power consumption units High scalability, high availability and real-time operation Standardized open interfaces Automated communication between all levels Coordinate distributed resources such that they become a stabilizing pillar to the system. Slide 9
Examples: Active voltage regulation in distribution grids Voltage constraints are frequently the first local constraint ABB s offering Characteristics and benefits Line voltage regulator for medium voltage, MV-LVR (< 33 kv) Line voltage regulator for low voltage, LV-LVR (<1 kv) ABB Smart R-Trafo (OLTC) Regulation of stationary under- and over-voltages, voltages sags and voltage imbalances Efficient integration of distributed generation along distribution feeders Limiting the voltage rise in the distribution grid enables the integration of larger amounts of renewable generation Installation next to an existing secondary substation, or supplied as an integrated part of a new substation. Avoids or reduces the need for grid expansion A active regulation of the voltage increase the integration capabilities of the distribution grid. Slide 10
Making renewable energy real Summary and outlook Building power systems on renewable sources is a holistic challenge It requires solutions ensuring best utilization of primary energy And it requires a system layout integrating as much as possible of the electrical energy available from renewable plants. Many solutions are available meanwhile more will follow. But not only solutions are key, but also profound understanding of the power system. ABB is committed to make renewable energy real! Slide 11
