Information

This example and the data are inspired by the article [P. Pourbeik and J. K. Petter, “Modeling and validation of battery energy storage systems using simple generic models for power system stability studies”, CIGRE Science and Engineering, October 2017, pp. 63-72.]
At initial time, the active power demanded by the battery is 0.5 pu (base SNom = 6MVA) and the reactive power is 0 pu (base SNom = 6MVA).
The BESS is able to discharge since the initial state of charge SOC0Pu = 0.5 is between the accepted range [SOCMinPu = 0.2 , SOCMaxPu = 0.8]. Since the simulation is only for 3 s, and the discharge time is considered much longer, the state of charge SOCPu is considered constant all along the simulation time.
At t = 1 s, a fault at the infinite bus is simulated and it can be seen that the BESS starts injecting reactive power until the fault is cleared at t = 1.5 s.
