With the continuous increasing proportion of new energy
the Multiple Renewable Energy Stations Short Circuit Ratio(MRSCR) has gradually become a critical indicator constraining power grid security. By analyzing key influencing factors and mechanisms of MRSCR
the results demonstrate that both the initial voltage of the power grid and nearby new energy output exert varying degrees of impact on MRSCR and transient stability. This paper explores practical approaches to enhance MRSCR from multiple perspectives including grid planning and construction
production and operation. It is proposed that MRSCR should be served as a reference index for new energy site selection and line selection
specialized MRSCR computational analysis should be conducted
and MRSCR should be used to estimate grid strength and predict renewable energy consumption capacity. Taking the recent grid planning framework of Inner Mongolian power system as an example
based on the principle of power differentiation control
new energy output optimization measures that meet MRSCR safety constraints should be formulated to provide innovative solutions for releasing renewable energy generation capacity.
