What Is Voltage Optimization Useful For?

Voltage Optimiser can improve voltage quality, reduce network losses, and enhance system safety and economy.

Voltage optimization provides dispatchers and operation planners with reasonable voltage adjustment control solutions by optimizing the operation status of the power system. Specifically, the functions of voltage optimization include:

‌Improve voltage quality‌: Voltage optimization can ensure that the voltage remains within the appropriate range, avoid damage to equipment due to excessively high or low voltage, and thus improve voltage stability and reliability.
‌Reduce network losses‌: By optimizing voltage levels and reactive power flows, voltage optimization can reduce power losses during transmission and distribution and improve the transmission efficiency of the power grid.
‌Enhance system safety‌: Voltage optimization helps prevent serious accidents such as voltage collapse and grid decoupling, thereby enhancing the safety and stability of the power system.
‌Improve economy‌: Voltage optimization can reduce the operating cost of the power grid, including reducing the investment in reactive compensation equipment and reducing electricity bills caused by line losses, thereby improving the economy of the power grid.

In addition, voltage optimization can also be combined with reactive power optimization to achieve more efficient distribution network operation. By optimizing and managing system-level voltage and reactive power flow, voltage/reactive power optimization (VVO) can minimize reactive power losses and improve distribution network efficiency.

In summary, voltage optimization plays an important role in the power system and is one of the important means to ensure the safe, stable and economical operation of the power grid.
