Low Frequency EMC and Power Quality Development of standards towards convergence BY DR. MAGNUS OLOFSSON FIGHTING CLIMATE CHANGE MEANS MORE ELECTRONICS In addition to power electronics, there is also an increased use of electronics for supervision and control. Electrification clearly facilitates our progress toward a resource-efficient and climate-friendly energy system. The share of electricity in total energy demand is projected to increase drastically in all the decarbonasation scenarios of the recent European Union (EU) Energy Road Map 2050 1 (Figure 1). Smart Grid is More than Networks Wind and solar power are examples of expanding technologies for renewable power. Germany now has 25 gigawatts of installed solar power 2 . Electric vehicles, light emitting diode lamps and heat pumps are energy efficient electrical technologies of importance when fighting climate change. In virtually all such technologies, electrical energy is passing power electronics. 34 IN Compliance April 2012 The smart grid is a very topical issue. The term is widely used by many, especially politicians. Now the International Electrotechnical Commission (IEC) has defined the concept of smart grid 3 . The definition states that the smart grid is an electrical energy system that uses information technology. The smart grid is thus not only related to electrical networks, but to entire the power system. With smart grid technologies as well as power technologies for renewables and improved energy efficiency, there is an increased use of electronics. We see growth in the use of power electronics, as well as electronics for information technologies. www.incompliancemag.com
