| description | In order to relieve the energy pressure and promote the clean transformation of energy structure, the new energy represented by wind power and photovoltaic power generation is connected to the grid on a large scale. However, due to the small inertia of the new energy unit, the proportion of conventional power supply decreases, and the system has the problems of frequency stability and voltage stability. In this paper, the reactive power distribution, voltage and frequency stability characteristics of the long chain connection channel of weak connection power network are studied. Combined with the actual situation of simulation and calculation of power grid A, the influence of photovoltaic centralized access on the load frequency characteristics of weak connection power network is analyzed, and some suggestions are put forward. |
