Summary

To achieve the energy transition goals under the Paris Agreement, high-voltage direct current

(HVDC) transmission technology is widely adopted to deliver renewable energy source (RES) over long distance to load center in power system planning. However, the high proportion of

RES and HVDC has reduced the resilience of power systems, posing risks to their security and stability. The HVDC capacity that the receiving end power system can carry is significant for planning decisions. This work focuses on the HVDC carrying characteristics of the receiving end power system, investigating from the perspectives of voltage and frequency stability. A simplified calculation and electromagnetic transient simulations incorporating

RES and HVDC are conducted to analyze the voltage and frequency stability characteristics under different power electronics (PE) penetration rates. Results indicate that increased proportions of RES and HVDC decreases system stability, limiting HVDC carrying capacity, while VSC-HVDC enhances voltage and frequency stability through power support. In addition, the traditional stability model needs to be optimized for future power system planning to adapt to high PE penetration scenarios.
