Improved power quality is the driving force for today’s modern industry. Consumer awareness regarding reliable power supply has increased enormously in the last decade. This has led to an additional bump to the development of small distributed generation (DG). Small isolated DG sets have the proficiency to feed local loads and thus leads to improvement in the reliability of power with low capital investment. These systems are also acquisition increased importance in isolated areas where transmission using overhead conductors or cables is unrealistic or prohibitive due to high cost and other circumstances. Small generation systems in rural areas, islands, hilly terrains, marine plants, aircraft, etc. can be efficiently utilizing even in developing countries. However, these DG sets could have to be de-rated if the induction motor loads are instantaneously started. One useful choice is to use DSTATCOM in a shunt structure with the central system so that the full capacity of producing sets is efficiently utilized. DSTATCOM consists of a voltage source converter (VSC), and it internally produces the required capacitive and inductive reactive power. Its control is high-speed and has the ability to provide acceptable reactive power compensation to the system to which it is connected. Before DSTATCOM, Thyristor based systems were proposed for reactive power compensation and were used for voltage flicker reduction due to arc furnace loads. However, due to the disadvantages of passive devices such as fixed compensation, large size, the opportunity of resonance, etc., the usage of new compensators such as DSTATCOM is growing to solve these power quality problems. The method of DSTATCOM for solving power quality problems due to voltage fall/dip, flickers, swell, etc., has been suggested. The purpose of DSTATCOM is to provide efficient voltage regulation at the point of standard coupling (PCC) and thus prevent significant voltage dips.
