Effective Power quality improvement using Dynamic Activate compensation system with Renewable grid interfaced sources

Rapid Industrialization and demand for Energy makes the distribution system more complicated. To address such issue robust control system is being developed for newly implemented microgrid and smart grid concepts. These control systems being a complex structure interconnects the renewable sources with the conventional sources of energy production. The power quality issues arising due to interconnection of number of variable generation system makes it more dynamic and fault oriented. The dynamics of the system is due to the use of power conditioning unit in the renewable system. Most of the power conditioning unit are of current source inverter type. However if these inverters can be made up of voltage source type then reactive power compensation can be achieved in addition to the active power supplied by the inverter into the grid. Dynamic Active Compensation System (DACS) is simulated through MATLAB to validate the performance.
