Quick advancements in the field of Energy utilization and production has been the key issue. The clean environment and green energy utilization for power production has remained the main point of attention. Low noise, longer and cheaper energy production costs has drawn the attention. But the intermittence in green energy production via these natural resources is the restriction in producing high efficiency and reliability in energy production. Different control schemes have been developed and many hierarchical structures have been proposed to achieve balanced energy from the renewable energy resources. These control schemes alter and addresses different issues in different ways to achieve sustainability but still the sustainability is the issue to be achieved. In this paper we have selected some recent control schemes in for to control the microgrids and finally presented a comparative analysis based on the schemes proposed.
