Power Quality and EMC in Smart Grid

Smart grid is increasingly seen as a means to facilitate climate friendly renewable energy sources (renewables) and to enable efficient use of electricity. For example, modern electrical networks can link wind- and solar power with electric cars. A consequence of smart grid is a drastic increase in use of electronics in the power system. This makes the satisfactory function of electrical and electronic equipment vital for realization of a robust smart grid. This paper focuses on the satisfactory function of equipment for smart grid with respect to electromagnetic disturbances, i.e. EMC - electromagnetic compatibility including power quality. Finally, a framework for the apportioning of responsibilities between network operators and the parties being responsible for the connection of equipment is proposed.
