    摘要: Systems, methods, and devices relating to operating a power generation facility to contribute to the stability of the power transmission system. A controller operates on the power generation facility to modulate real power or reactive power or both in a decoupled manner to contribute to the stability of the power transmission system. Real power produced by the power generation facility can be increased or decreased between zero and the maximum real power available from the PV solar panels, as required by the power system. Reactive power from the power generation facility can be exchanged (injected or absorbed) and both increased or decreased as required by the power transmission system. For solar farms, the solar panels can be connected or disconnected, or operated at non- optimal power production to add or subtract real or reactive power to the power transmission system.

    摘要: In order to stabilize the system voltage in a network section (1) that is connected via a device with a variable voltage transformation ratio to a higher-level network (3) and that comprises at least one energy consumption and/or generation unit (8, 10, 11), the voltage transformation ratio is varied in order to vary a system voltage level in the network section (1). At least in one mode of the method, the system voltage level is increased in order to counteract an increase in the system voltage at the energy consumption and/or generation unit (8, 10, 11), and/or the system voltage level is lowered in order to counteract a decrease in the system voltage at the energy consumption and/or generation unit (8, 10, 11). This is effectively possible because the power consumption and/or output of each energy consumption and/or generation unit (8, 10, 11) in the network section is controlled via a characteristic curve of the system voltage present there, the characteristic curve raising the power consumption of the energy consumption and/or generation unit (8, 10, 11) with an increasing system voltage and lowering the power output of the energy consumption and/or generation unit (8, 10, 11) with increasing system voltage.

The system comprises a plurality of inverter modules (404) having a switched capacitor across its ac power output, a power measurement system coupled to a communication interface, and a power factor controller to control switching of the capacitor. A system controller (410) receives power data from each inverter module (404), sums the net level of ac power from each inverter (404), determines a number of said capacitors to switch based on the sum, and sends control data to an appropriate number of the inverter modules (404) to switch the determined number of capacitors into/out of said parallel connection across their respective ac power outputs.

    摘要: A controller is disclosed for hybrid systems providing power to an electrical power grid. The controller reduces wear on hybrid systems by having only a fast unit tuned to track fluctuations of a regulation signal in a normal mode of operation. By contrast, the slow unit does not track fluctuations in the regulation signal in the normal mode of operation, which reduces wear on the slow unit. The normal mode of operation is defined by an energy range of the fast unit. Energy band parameters associated with the energy range can be dynamically modified in order to optimize the efficiency of the hybrid system.
