Problems solved by technology

Due to the nonlinear characteristics of the STATCOM model, if a large disturbance occurs or the operating point deviates too far from the normal value, the performance of these controllers will be greatly reduced. To minimize the occurrence of large-scale power outage accidents, it is difficult to effectively guarantee the reliability and continuity of electricity consumption for people's living and economic development
