An improved micro-grid stability by balancing active and reactive power. By using Droop control method

      Аннотация: A micro-grid, there will be many DGs and those DGs have to operate in synchronizing to each system. Some of DGs such as wind or PV may not be in position to operate as controllable power generation. But in some DGs power dispatching may controllable and may be improved to work as active generators. The micro-grid will be interconnecting through back-to-back converter to the main-grid. Frequency droop method will be implemented in micro-grid side of the back-to-back converter, and active generators in micro-grid have to change their power dispatching based on this frequency droop. In this micro-grid, four inverters will be operating in parallel to provide power for the micro-grid loads where back-to-back converter provides the based load power.
