Abstract: In one aspect of the teachings herein, a self-commutated current source converter is operated in a manner that compensates for the reactive power consumption and/or harmonics generation of a line-commutated current source converter used in the transfer of electrical power between an AC power system and a DC power system. In this regard, the line-commutated current source converter is operated as a first converter in a hybrid converter apparatus and the self-commutated current source converter is operated as a second converter in the hybrid arrangement. According to one example, the first and second converters are stacked, such that each shares a portion of the DC voltage on the DC side of the hybrid converter apparatus, while in another example, the second converter is not used for power conversion and instead is used solely for compensation with respect to the first converter.

Abstract: A protection device includes a diode having its forward direction in a normal power flow of a region of a DC collection system, a first switch in parallel with the diode, a second switch in series with the diode and a control unit for controlling the switches. The first switch can be opened so that current can flow through the diode in the forward direction without the first switch bypassing the diode, and closed if no current is flowing through the diode in the forward direction and power is needed upstream of the diode. The second switch can be closed so that current can flow through the diode in the forward direction to an AC grid interface of the DC collection system, and opened if no current is flowing through the diode in the forward direction due to a fault in a DC feeder to which the device is coupled.

Abstract: A control apparatus and corresponding control method use per-unit filtering in a plurality of power-sharing controllers, to obtain a power-sharing command signal for respective ones among a plurality of different energy storage units in a hybrid energy storage system. The hybrid energy storage system includes two or more types of energy storage units and the power-sharing command signal for each energy storage unit is obtained by filtering an input signal using a filter having a filter response that is tailored to the energy storage characteristics of the energy storage unit. The input signal reflects load variations on the electrical grid and may be locally generated or provided by a remote node. While the power-sharing control loops used for each energy storage unit advantageously may be the same in terms of architecture and implementation, each loop uses tailored, dedicated filtering and, possibly, individualized values of one or more other control parameters.

Abstract: A dual-voltage power generation system includes a prime mover configured for adjustable speed operation and a doubly-fed induction generator driven by the prime mover and including a multi-phase stator winding and a multi-phase rotor winding. A first output terminal of the dual-voltage power generation system is electrically connected to the multi-phase stator winding, and a second output terminal is electrically connected to the multi-phase rotor winding.

The multi-phase stator winding has a different turns ratio than the multi-phase rotor winding and the first output terminal is electrically isolated from the second output terminal so that the generator has two isolated power supply outputs at different voltage levels in a first configuration.
