Abstract
Renewable energy like solar energy, wind energy and hydropower energy may be used to connect with grid-connected distributed system. The excess energy available by renewable energy sources may be supplied to grid and to get some positive cash flow. In this paper, application of power electronics has been explained and discussed and also providing some simulation results to be used with grid-connected distribution system. To achieve a reliable working of grid-connected distribution system, active and reactive power are suggested as compensation for decrease of grid voltage due to the reactive power injected to the grid. Absorption of reactive power has been accompanied with increase in active power injection. Also, increase in active power absorption has been accompanied reactive power injection. Rated active power has been supplied to the grid voltage. The active power injection has been decreased till minimum optimized value of active power being achieved.
