Local control of fully inverter based micro grids in islanding operation mode considering generation disturbances in RES

Abstract

The importance of renewable energy resources (RES) due to low emission level of greenhouse gases besides the increasing rate of fossil fuels costs on the one hand is growing every day. On the other hand, the application extension of these resources in costumer side introduces a new concept called Micro Grid having the capability of grid connected as well as islanded operations. In this paper, the local control of micro grid with renewable resources as well as controllable resources and storage is developed in islanding operation mode using control scheme of inverter mediation of storage which effectively controls the micro grid locally by contribution of controllable resources. Then, the behavior of storage and controllable resources are investigated considering the generation disturbances of renewable resources. The micro grid parts are simulated in MATLAB/ Simulink environment.
