A method in a controller controlling a dynamic power compensator. The dynamic power compensator is arranged to provide active and reactive power to an electric power system, the dynamic power compensator including a battery energy storage. The method includes the steps of: monitoring a state of charge of the battery energy storage; detecting a voltage level in the electric power system requiring increased delivery of the reactive power to the electric power system; and controlling the battery energy storage 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.

A system for generating electric energy from renewable energy sources such as waves includes a plurality of generator aggregates (-) arranged in the sea and a plurality of switchgears (-) arranged in the sea. Each switchgear (-) is connected to a plurality of the generator aggregates (-). A plurality of primary intermediate stations (-) are respectively connected to a plurality of the switchgears, and a secondary intermediate station () is connected to a plurality of the primary intermediate stations (-). The secondary intermediate station is also connected to a land based electric network. Switching means () is present for allowing selective connection to various locations () in the electric network.
