Research and Application of Three Level Coordinated Control of Reactive Power and Voltage in Distribution Network

With the development of economy, the power quality of distribution network in countryside cannot meet the needs of people's requirements. The traditional reactive power and voltage control method can not solve the problem of low voltage on the user side. The paper establishes the mathematical model of coordinated control of reactive power and voltage, then introduces the coordinated control process of reactive power and voltage. At last, combining with the project example, the effectiveness and practicability of coordinated control are verified.
