Abstract: This paper discusses control logic of multi micro grid in different conditions and optimisation set point algorithm. In today's world, a stable power supply is considered as a basic necessity, almost a fundamental right to serve critical facilities. Huge capital is needed to install traditional power plants, so micro grids and multi micro grids are better choices. There is a lot of scope for power generation by using small power generating units like micro grids and combination of multi micro grids. So, there is a need for a control unit for maintaining constant frequency and voltage and provide a good service for consumers and it is free of pollution. This project proposes a new control unit for islanding mode micro grid of a multi micro grid system which consists of distributed energy resources (DERs) such as solar PV, diesel generator, micro hydro model, battery bank with a bi-directional inverter and critical and non-critical loads. It can be operated in multi micro grid with main grid mode, multi micro grid mode as well as island mode.
