Vanadium Redox Flow Battery Control in Flexible Microgrids
This paper discusses the control of flexible microgrids consisting of a Redox Flow Batteries (RFB) and a new power conditioning system (PCS) for the RFB. Considering the importance of energy storage, this study is essential in power systems that are developing cautiously. RFB is connected to power system by a DC/DC or DC/AC converter producing a DC voltage. It is very important that this converter to be effectively be modeled and controlled for the applications in microgrids. This paper focuses on control the active power and the reactive power simultaneously in RFB systems. In this regard, this study proposes a new Flexible AC Transmission System (FACTS) compensator for microgrids which is able to control the active and reactive power. This type of compensator presents a good transient response. The simulation results show the validity of the proposed system. Simulations are performed by using Matlab-Simulink block set.
