In these, we are using ES ‘Electric Spring’ which called as smart gird device which used to dispatch Real and Imaginary power in the system which is connected between the Gird and Load or demand and supply. Fuzzy optimization techniques compared with other conventional technologies and adopted best results. The damping controller is designed by using the fuzzy logic controller. The main conclusions have been drawn on the suitability of the optimization technique. This control system also provides an opportunity for better usage of Electric Spring thereby improving Quality Voltage and Quality Power along with Renewable Energy Microgrid.

INTRODUCTION Power quality can be defined as any power problem faced by the deviation of frequency, current or voltage that leads to the customer's equipment system failure. Maintaining the efficiency of electric power to keep it within acceptable limits has always been challenging. The degradation of power quality is mainly due to the use of power electronics devices that act as a nonlinear load. In the distribution systems, low power quality results in numerous problems such as higher power losses, harmonics, voltage sag and swells, poor distortion and displacement factor. Recent developments in communications, digital electronics and control systems have rapidly increased the number of critical loads needed for proper operation by the ideal sinusoidal supply voltage. So it became important to provide some kind of compensation to meet the standards-proposed limits. Various FACTS devices are available here for DVR, SSSC, STATCOM, UPQC, DSTATCOMetc.…, to boost power efficiency, 2. PROBLEM IDENTIFICATION A. The deficiencies occurring in the determination of nonlinear load result in low-quality power. B. Low-frequency oscillations are found when relatively weak tie lines interconnect wide power systems. FACTS (Flexible AC Transmission Systems ) devices play the role of a very cruise for the present development in the field of power electronics.FACTS devices can control the structure of the system very fast and this FACTS function can be used to increase the reliability of a power system. To deflate electromechanical oscillations in the power system, the extra controller can be used with FACTS devices to boost system damping. The damping controller is called the supplementary controller. In the speed deviation process, the damping controllers are designed to produce electrical torque. C. In the power system network, power demand is variable means load variance critical load, non- linear loads, non-critical loads always produce suppression of power quality. D. PQ disruptions such as harmonics and starting and ending unbalancing due to any faults (Symmetrical/Asymmetrical) in the power system network in all phase load currents.

These smart loads are designed to reduce the power imbalance in a control system. By illustrating similarities to a conventional mechanical spring, the Electric Spring idea was introduced. It could be
