Multi-reactive power source cooperative control method

The invention discloses a multi-reactive-power-source cooperative control method, and the method comprises the steps: proposing a VRPI index to represent the voltage regulation participation capability of each reactive power source according to variables such as the total reactive power vacancy, the reactive power residual output and the transient response time of each reactive power source under the fault condition of a multi-reactive-power-source AC system; and a multi-reactive power source cooperative control method is provided based on the index, so that when the multi-reactive power source cooperative control method is applied to an alternating current side short-circuit fault of a large-scale alternating current and direct current system, the influence of the reactive power sources on system fault response can be quantified, smooth ride-through of the wind turbine generator during the fault period can be ensured, transient overvoltage can be effectively inhibited, and tripping of the wind turbine genera
