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 developed cautiously. RFB is connected to power system by a DC/DC or DC/AC converter to produce a DC voltage. It is very important that this converter be effectively modeled and controlled for applications in microgrids. This paper focuses on simultaneous active and reactive power control 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, performed by MatlabSimulink toolbox, show the validity of the proposed system.
