The Application for Automatic Voltage Control Technology Considering Energy Storage in Regional Power Grid

摘要

Compared with the traditional energy, energy storage power stations using emerging clean generation technology have the advantages such as peak regulation, voltage regulation, and suppressing power fluctuation of grids. Due to its advantages of eliminating voltage overstepping and optimizing reactive power, automatic voltage control (AVC) system has been widely used in power grid control system in recent years. In this paper presents a voltage coordination control technology for regional grid energy storage stations considering the reactive margin, and elaborates the principle and the implementation of the control scheme. The practical application of the site shows that the control strategy of this scheme is feasible and effective, and it can effectively exert the advantages of control voltage and optimal reactive power of the energy storage power station, which is conducive to improving the stability and power quality of the power grid.
