Abstract: A battery system for storing electric energy, e.g. from a wind turbine. Battery modules are distributed in a housing and cooled by a housing cooling system. A monitoring algorithm receives input data from temperature and current sensors in battery cells from each of the battery modules, a state of a cooling system in each of the battery modules, a state of the housing cooling system such as fan rotation speed, and auxiliary inputs such as an ambient temperature. The monitoring algorithm processes the input data according to a predetermined model based on knowledge about the battery system. The model based estimated temperature within a specific battery cell is compared with the measured temperature to determine whether an abnormal operation exists.

Abstract: Aspects of the present invention relate to controlling a renewable energy power plant comprising a plurality of wind turbine generators (WTG)s and an energy storage system (ESS). A method includes: controlling the plurality of WTGs to stop generating power, and thereby to enter a non-exporting mode of operation of the renewable energy power plant, during which one or more auxiliary systems of the renewable energy power plant are powered to maintain at least one of the plurality of WTGs in a standby state, operable to start generating power upon demand; wherein the one or more auxiliary systems are powered during the non-exporting mode of operation.
