Voltage Optimizer Voltage Optimization

Voltage Optimiser refers to the optimization of voltage distribution in power grids or power systems through various technologies and methods to improve the efficiency, stability and safety of power transmission and distribution.

Voltage optimizers can be applied to different scenarios and technologies. For example, in distribution networks, voltage optimizers can be implemented by reactive-active power combined voltage regulation. This method uses distributed power sources (such as photovoltaic power generation and wind power generation) and reactive compensator equipment to optimize the voltage distribution of unbalanced distribution networks by building active and reactive power support models, as well as distribution network voltage distribution enhancement indicators and voltage imbalance indicators.

In addition, flash memory reference voltage optimizers are also an important application area. By optimizing the reference voltage setting of flash memory, the reading performance and stability of the memory can be improved. This usually involves the configuration and optimization of the voltage generator and the reference voltage setting module to ensure that the reference voltage is set to the optimal value.

In terms of reactive voltage optimization, it supports coordinated control at the provincial, prefectural and county levels, as well as coordinated control of reactive power optimization of high and medium voltage distribution networks, which can achieve reactive optimization of the entire county-level power grid. This includes the optimization control of reactive power sources such as small thermal power, wind turbines, and SVC in the distribution network, as well as the coordination of reactive power optimization planning and reactive power optimization control ‌

In addition, the voltage optimization control strategy of the distribution network taking into account multiple photovoltaic and storage integrated devices is also an important direction of the voltage optimizer. This strategy realizes the voltage optimization control and rapid voltage over-limit management of the grid-connected nodes of multiple photovoltaic and storage integrated devices through two stages: centralized rolling optimization and distributed voltage real-time control ‌

On a broader level, the coordinated optimization of distribution network voltage and reactive power to minimize operating costs is also an important consideration. This includes converting non-convex optimization models into second-order cone programming models so that they can be solved using existing optimization algorithms, while taking into account the access problem of distributed power sources and the optimization of transformer tap positions and the number of capacitor access groups ‌

Finally, specific reactive voltage optimization control strategies can also be proposed for distribution networks with high photovoltaic penetration. These strategies may involve the calculation and optimization of IGBT junction temperature, as well as the establishment of a multi-objective reactive power optimization model for active distribution networks considering IGBT junction temperature constraints ‌

In summary, voltage optimizer is a complex and multidimensional process involving the application of multiple technologies and methods. Through reasonable optimization and control strategies, the efficiency and stability of the power system can be significantly improved.
