ELECTRIC POWER SYSTEM COORDINATED CONTROL METHOD

摘要

The present invention relates to the technical field of electric power system control. Disclosed is a coordinated control method, comprising the steps of: S1. measuring the real-time voltage, current, active power and reactive power of each bus node, and setting an AGC instruction; S2. verifying the voltage according to the AGC instruction, and exporting an predicted voltage value and the verification result of a selected bus node; S3. if the AGC instruction satisfies the voltage requirement, then exporting the ACG instruction; otherwise execute step S4; S4. performing AVC according to the predicted voltage value of the selected bus node, and calculating a voltage adjustment value of the selected bus node after AVC is performed; S5. verifying the power according to the voltage adjustment value of the selected bus node, and exporting a predicted power value and verification result of a connecting line; S6. if the AVC instruction satisfies the power requirement, then exporting the AVC instruction; otherwise resetting the AGC instruction and return to executing step S2. The method of the present invention is capable of controlling well the active power flow and reactive power flow of a power system, thus improving the economy and safety of power system operation.
