摘要： The present invention relates to a method for enabling dynamic evaluation of performance of a battery energy store. The method comprises measuring (2) real-time parameters (V, I, T) of a battery energy store (1), estimating (3) a state of charge (SOC) for the battery energy store, the estimation being based on the measured real-time parameters and off-line data (4) of the energy store, identification (3) of R-C parameters for an equivalent circuit model (ECM) of the battery energy store, the identification being based on the measured real-time parameters, updating (5) a look-up table with the identified R-C parameters for different operating conditions, and simulating (5) performance of the battery energy store based on two or more operating conditions. A system, a marine vessel and a computer program product thereof are also presented.

摘要： A photovoltaic power plant system (1) for power generation is provided, comprising one or more photovoltaic clusters (18a, 18b, 18c, 18d) and one or more modular multilevel converters (22). Each photovoltaic cluster (18a, 18b, 18c, 18d) comprises a number of photovoltaic strings (14) connected to one or more MPPT DC/DC, converters (17a) connected to a common LVDC, bus. Each photovoltaic cluster (18a, 18b, 18c, 18d) comprises a DC/DC converter (13a) comprising an input connected to the LVDC bus, and an output connected to a MVDC collection grid (29a, 29b). Each of the one or more modular multilevel converters (22) comprises an input connected to the one or more photovoltaic clusters (18a, 18b, 18c, 18d) via the MVDC collection grid (29a, 29b) and an output connected to a transmission grid (23).

摘要： The present disclosure relates to a method of controlling a microgrid arrangement (1) comprising a microgrid (6), a plurality of Distributed Generators (DGs) (2a, 2b.2c) connected to the microgrid (6), and a switch (5) for, in a closed position, connecting the microgrid (6) to a power grid(4), and for, in an open position, disconnecting the microgrid(6) from said power grid (4). The method comprises detecting instability in the microgrid(6). The method also comprises, in response to the detection, switching operating mode of a first DG (2a) of the plurality of DGs from a grid following mode to a grid forming support mode and of a second DG (2b) the plurality of DGs to a grid forming mode. The method also comprises, when the first DG(2a) is in the grid forming support mode, controlling output to the microgrid (6) from the first DG (2a) based on a first voltage reference during a transient state of the microgrid and based on a power reference during a steady state of the microgrid, and controlling output to the microgrid from the second DG (2b) based on a second voltage reference during both the transient state and the steady state.

摘要： A method of controlling a microgrid arrangement including a microgrid having a plurality of switches, and a plurality of Distributed Generators arranged for being connected to the microgrid. The method includes obtaining information about the microgrid arrangement. The method also includes, based on the obtained information, dynamically linking a first group of switches, of the plurality of switches, to each other. The method also includes detecting an event in the microgrid, and in response to the detection, automatically opening closed switches in the first group, whereby a first segment of the microgrid is disconnected from a second segment of the microgrid.
