Solar energy technologies are need of the hour due the depletion of the existing conventional energy resources. The major advantage of solar energy is the eco friendly nature and abundant availability. The problem of harmonics persists everywhere in the power system whenever non linear load or static devices are involved. The ultimate goal of the power system to deliver quality power to the consumer. The paper describes the novel method of using Shunt active power filter in gird interfaced PV system in presence of static loads which exhibit non linearity between voltage and current. This system provides VAR compensation and also takes care about harmonics using droop control technique. The solar module is connected the power filter, where the DC-DC converter acts an interfacing medium. The solar module is combined with an appropriate power tracking algorithm which surpases the disadvantages of the usual traditional method. The simulation study shows the effectiveness of the proposed system. MATLAB Simulink platform is utilized to demonstrate the uniqueness of the proposed system .

INTRODUCTION The power demand is always behind the electric power supply in ever growing and developing country like India. This calls for the essence of the non conventional energy sources like solar, wind ,hydro etc. The conventional methods of power generation are taking backstage due to depleting nature and preference is given by the Indian government to promote new and alternate energy generation methods in sustainable manner. The growth and development of SCR in thyristor family generally accounts for extensive use of static equipment. This also leads of the problem of harmonics or distortions in the voltage and current waveforms. Another major problem at the load side is the watt-less power requirement. The shunt active power filter is generally used in the power system as it takes care of both these problems. The main aim of this equipment is that it supplies a current which is same as harmonic distorted current in terms of value but anti parallel in direction in order to nullify the effect of harmonics. There are various names for Shunt active power filter such as active power filter, power filter, active filter, SAPF, APF are predominantly used in this paper. The system considered here is the solar system connected the gird and SAPF mitigates reactive power requirement as well as harmonic content ABSTRACT Available online at: http://www.ijmtst.com/vol6issue02.html International Journal for Modern Trends in Science and Technology ISSN: 2455-3778 :: Volume: 06, Issue No: 02, February 2020 41 International Journal for Modern Trends in Science and Technology Dr. L V Narasimha Rao, “Solar PV System by Grid-Tied Connected to Droop Control Strategy for Shunt Active Power Filter Application” Fig.1 Schematic diagram of active power filter The AC supply is fed the static load , in this case it is the diode based rectifier with resistive and inductive load,
