Implementation of P&O method for smart inverter PV STATCOM to Control power in Distribution System

Abstract

In this paper, the design and implementing of P&O method for smart inverter PVSTATCOM to control voltage in distribution system, in which a PV smart inverter can be controlled as a reactive power compensator. The distinguished feature of implementing of P&O method for smart inverter PVSTATCOM, to provide DC link voltage control faster during critical system needs and improve transient performance of the system. In the day time, during disturbance on critical system, the PV smart inverter discontinues temporarily its active power generation function and freeing its entire inverter capacity for STATCOM operation. Once the disturbance is cleared and the need for grid voltage control is fulfilled, the solar farm returns to its pre-disturbance real power production. In the night time, the entire inverter capacity is utilized for STATCOM operation. A MATLAB 2019a Simulink-based study is presented in day time and night conditions under different loads to validate the proposed distribution system.
