Sharing reserves through HVDC: Potential cost savings in the Nordic countries
Abstract During summer 2018, the Nordic system's kinetic energy dropped below a critical level. As a consequence, Svenska kraftnät, the Swedish transmission system operator, requested the largest production unit to reduce its power output to guarantee system's security. This action resulte...
