Integrating SVG functionality into solar inverters eliminates the need for separate SVG equipment. Hence, it simplifies system design, reduces installation costs, and improves scalability for solar power plants of various sizes. Even one of unit failed, the total reactive compensation power of the whole system will not be affected. Conclusion:
In solar power plant applications, SVGs are used to regulate and control the flow of reactive power in the electrical system. Reactive power is an important aspect of power systems that is necessary for voltage control and maintaining system stability. It consists of three basic functional parts: sensors, controller and compensation output module.
Retaining the active power at zero in Fig. 8b indicates that the inverter has the ability to inject pure reactive power without consuming active power from the grid. Finally, the results validated that this inverter model can be used during the night as a pure reactive power generator without consuming any active power from the grid.
In this article, we will explain the concept of SVG and how SolaX C&I on-grid inverters can be utilized with integrated SVG functionality, leading to improved power quality and enhanced grid stability. Static Var Generator (SVG) is a power electronics-based device that provides dynamic reactive power compensation in various applications.
By rapidly absorbing or injecting reactive power as required, SVGs mitigate voltage fluctuations, minimize line losses, and improve overall power quality. Overall, SVGs play a crucial role in reactive power compensation in solar power plant applications, ensuring optimal performance and grid stability.
The PV inverters theoretically can be developed as reactive power supporters, the same as the static compensators (STATCOMs) that the industrial standards do not address . Typical PV inverters are designed to be disconnected at night. Alternatively, it is possible to use its reactive power capability when there is no active power generation.
