Control of Integrating DG’s consists of several objectives such as voltage, current, harmonics, frequency, active and reactive power depending on the requirements. Among these objectives the voltage and harmonics is the best considerable one. This Article presents a integrated DG’S aimed to provide a large amount of power generation to grid and continues supply to load and maintaining the grid voltage as constant. These systems need to be controlled properly in order to reduce the harmonics presented in the system. For the reliable operation of Integrating DG systems, under both balanced conditions, unbalanced conditions and faulty conditions by using conventional Integrating controller at all the generating units which are integrated and subsystem controller at PV system to maintain maximum power point. The results of the proposed controller of various cases with different values of harmonic changes at filter are compared with required parameters. It is observed from the results Conventional integrating controller gives better solutions.
