This paper proposes grid system and its controlling techniques to regulate the continuous changes in
operational requirements and deregulation problems. In the present scenario, the distribution energy
systems play an important role in maintaining the power system reliability and stability in distribution
domain. The proposed grid is a structure of PV and hybrid system. To achieve the maximum operation from
the renewable sources an MPPT methods is proposed. This paper also proposes a concept for controlling of
reactive power in single phase grid connected PV system. In order to achieve this reactive power control, this
paper is implemented with different current regulated controllers such as conventional PI controller, PR
controller, ASDM controller and Fuzzy Logic Controller. This proposed system with different controllers are
tested and verified in MATLAB environment.
