Abstract: The invention relates to a method (20) in an electric power system (1) comprising one or more power generation source (s) (3, 4, 5) and a dynamic power compensator (6) having a battery energy storage (10). The method (20) comprises the steps of: detecting (21) a frequency disturbance within the electricity power system (1) requiring an additional power generation source (3, 4, 5) to be connected to the electricity power system (1) in order to meet a power demand; and controlling (22) the power output from the battery energy storage (10) of the dynamic power compensator (6) during start-up of the additional power generation source (3, 4, 5), thereby limiting the frequency disturbance within the electric power system (1). The invention also relates to a controller, computer program, computer program products and electric power system.

Abstract: The invention relates to a method (50) in a controller (18) controlling a dynamic power compensator (10). The dynamic power compensator (10) is arranged to provide active and reactive power P, Q to an electric power system (17), the dynamic power compensator (10) comprising a battery energy storage (14). The method (50) comprises the steps of: monitoring (51) a state of charge of the battery energy storage (14); detecting (52) a voltage level in the electric power system (17) requiring increased delivery of the reactive power Q to the electric power system (17); and controlling (53) the battery energy storage (14) in dependence on the monitored state of charge and detected voltage level. The invention also relates to a controller, computer programs and computer program products.
