A new concept in power generation is a micro grid. Isolated micro grid system is a small scale independent power system having renewable energy sources- solar and wind power sources and backup by controllable sources- diesel generator, and fuel cell. The objective of this research is to develop a novel control scheme that can compensate for power and frequency deviation in micro grid. Micro grid consist of renewable sources whose output is not constant. Similarly load on the system is also not constant. Due to these variation power and frequency deviation occurs. For the solution of this situation in this research proposes a scheme called “Smart Control of parameter of micro grid having renewable sources.” The model of this proposed scheme is making out in the MATLAB/Simulink Software (R2012a). In this PID controller is used to control the input parameter of controllable sources according to variation in generation and load and mitigate the problem of power and frequency droop. Participating in Smart Control of Sources. These GRC and P-f droop make the system non linear and we have proposed a Ziegler Nicholas based and Artificial Intelligence based optimization to tune important parameters simultaneously in micro grid. The comparison of Ziegler Nicholas method to tune the PID controller and in the same system Fuzzy controller is use in place of PID. The proposed method improves dynamic and steady state response of the micro grid and maintains the system frequency at desired level.
