Abstract :
With the world´s energy sources crisis and environment pollution increasingly aggravating, distributed generation (DG) based on renewable energy has become a development trend for electric power industry in the 21 century. But DG affected by natural conditions can not output power continuously and steadily. So DG connected to grid system certainly will bring a series of problems to the steady operation of electric power system. In this paper it is presented using energy storage system to solve problem on electrical power quality result from DG connected to power grid. On the basis of various energy storage technologies being contrasted, a optimum solution of super capacitor energy storage system (SCESS) based on DG connected to power grid is presented in this paper. This solution may reduce disadvantage impact caused by DG connected to grid system and ensure stability and reliability of system operation.
