Power flow management and voltage control using solar and wind farm inverters in multi line system

This paper presents the utilization of solar and wind farm inverters to manage the power flow and voltage control in an interconnected power system. In this, the inverters of photovoltaic (PV) solar power farm and wind power farm are configured in such a way that it acts like an interconnection between two adjacent power system networks/feeders. This is accomplished by connecting the inverters in a back to back fashion. The reconfigured system then can be controlled appropriately to serve the purpose of power flow management and voltage regulation in a multi line transmission/distribution system. This functionality of proposed configuration for solar and wind power farms is in addition to their normal feature of generating renewable power. The proposed configuration basically uses the inverter capacity left after real power production. Besides this, the proposed configuration has various applications like load reactive power support, increase in stable transmission limit, power system damping and so on. A simulation study is carried out to determine the capability and effectiveness of proposed system.
