    Abstract: A method for controlling charging of at least one electrical storage device (5, 21, 22) is disclosed. Information regarding a power grid and the at least one electrical storage device (5, 21, 22) is retrieved by an aggregator (1), and the aggregator (1) derives a weighted distribution of virtual inertia response and fast frequency response to be provided to the power grid by the electrical storage devices (5, 21, 22), on the basis of the retrieved information. The derived weighted distribution of virtual inertia response and fast frequency response is provided to a charging controller (4), and a total power available for charging the at least one electrical storage device (5, 21, 22) is derived in accordance with the weighted distribution by the charging controller (4). An active power setpoint is derived for each of the at least one electrical storage device (5, 21, 22) on the basis of the total available power, and on the basis of the information regarding the at least one electrical storage device (5, 21, 22). Finally, a charging state of each of the at least one electrical storage device (5, 21, 22) is controlled based on the derived active power setpoint.

    Abstract: Embodiments herein describe optimizations for hybrid power plants that include wind turbine generators and photovoltaic generators by determining solar tracking setpoints for a field of photovoltaic generators co-located with a wind turbine generator, wherein the solar tracking setpoints orient a collector face for each photovoltaic generator sunward; in response to determining based on data received from the wind turbine generator that an airborne impactor event is occurring, adjusting the solar tracking setpoints to reposition the collector face out of a trajectory for airborne impactors; and transmitting the setpoints to tracking motors for the photovoltaic generators of the field.

    Abstract: A grid connected battery storage system (1) comprising two or more AC/DC power converter systems (2), two or more DC/DC power converters (8), and two or more DC electrical storage units (7), such as batteries, is disclosed. Each DC/DC power converter (8) has at least one DC electrical storage unit (7) connected thereto, in such a manner that the voltage capability of the DC electrical storage unit(s) (7) matches the DC voltage level rating of the DC/DC power converter (8), thereby forming at least one DC block (3), each DC block (3) having a voltage capability defined by the voltage capability of the DC electrical storage unit(s) (7) of the DC block (3) and a DC voltage level rating defined by the DC voltage level rating(s) of the DC/DC power converter(s) (8). Each DC block (3) is connected to a DC/AC power converter system (2) via a DC bus bar (10, 11) and at least one switch (6), in such a manner that the DC voltage level ratings of the DC/AC power converter systems (2) match the voltage capability of the DC blocks (3).

    Abstract: A power plant comprising: a plurality of photovoltaic (PV) modules arranged in a first and a second region of the power plant, wherein the PV modules in the same region are electrically connected with each other and wherein the PV modules of the first region are electrically connected to a local grid of the power plant via a first converter, and the PV modules of the second region are electrically connected to the local grid via a second converter; and a wind turbine generator (WTG) which is arranged such that the WTG is able to cast a shadow over at least one of the PV modules; wherein the first region and the second region extend in a substantially radial direction away from the WTG such that at most one of the two regions is at least partially covered by the shadow of the WTG at any time.
