Research on Dual-Mode Control Strategy of Energy Storage System in Microgrid

As wind power, solar and other new energy development, new energy itself has intermittent, fluctuation characteristics, which bring great challenges to the safe and stable operation of power grid. This paper will construct semi real object simulation system research platform with the RTDS real-time simulation system, storage controller, power amplifiers and other equipment, focus on control strategy of energy storage system in a Micro Grid, mainly grid PQ control, off-grid V / F control and two conditions of each conversion control technology.
