【 摘 要 】

Voltage level is one of the most important indicators in the operation of power systems. This paper proposes a method for suppressing voltage fluctuations in the grid with impact load using parallel FACTS with energy storage. This paper first analyzes the reasons of the voltage over-limit and voltage fluctuation of the actual grid-SZ grid, then points out the lack of voltage adjustment means in the actual operation. The parallel FACTS with energy storage mathematical model is given, and the controller structure of this kind of device is analyzed. By adding the parallel FACTS with energy storage to the SZ grid and using the actual operating data to carry out simulation calculations, the calculation results show that the use of parallel FACTS with energy storage has a good inhibitory effect on the voltage fluctuation and voltage over-limit problem, which can be used as a new voltage control method for the SZ grid planning and operation.
