Energy management strategy of field power station based on differential hysteresis voltage stabilization

Abstract The existing field power stations mainly use diesel generator sets for supply, with poor supply stability and no uninterrupted capability. Therefore, a hybrid energy storage device is introduced into the station to improve it. According working characteristics of different sources, an management strategy based on differential hysteresis voltage stabilization proposed. Hysteresis control makes it true that set as main source works long time, battery backup when necessary. Differential realizes coordination two, which allows exit work smoothly. can get transient stable economy, extend life battery. Simulation results show this superior traditional strategy.
