Abstract: An electrical power system includes a plurality of generator sets (gensets) having different response capabilities which are connected to a common bus that is coupled to an electrical load. The gensets may be operatively associated with one or more electronic controllers. Each genset has an operational range applied to it and a power target set for it. In the event of a change in the power demand by the electrical load, the operational ranges and the power target setting are changed according to the response capabilities of the individual gensets. To facilitate the change, the faster responding genset can operate intermittently according to various methods to generate additional power to compensate for the power deficiency of the slower responding genset as it adjusts to its changed settings.

Abstract: A control system, apparatus, and method to control load sharing of multiple generator sets of a power supply system are described. Load transient set points to add an individual generator set can include a transient percentage threshold to characterize load transients as a load transient, a transient count threshold, and a transient count time period during which a detected number of load transients is compared with the transient count threshold. A controller can determine whether to add the individual generator set based on whether the detected number of load transients is equal to the transient count threshold within the transient count time period and control addition of the individual generator set responsive to the detected number of load transients equaling the transient count threshold.

Abstract: A system for allocating power generation between a constant speed generator set and a variable speed generator set. A controller determines an operating power demand from on-line consumers, and determines an anticipated transient power demand from a new consumer or one with an increasing power demand. The controller allocates the electrical power response between the generator sets to meet both the operating power demand prior to a transient condition and the total power demand upon the occurrence of the transient condition. The allocation may be based upon operating modes of the system.

Abstract: A control system to optimize response time of a plurality of engines of a machine is provided. The control system includes a controller configured to determine a first engine group and a second engine group based on data regarding response time characteristics of the plurality of engines, control the first engine group to increase output power of the machine when the output power of the machine is below a predetermined power output threshold, and control the second engine group to increase output power of the machine responsive to the output power of the machine reaching the predetermined power output threshold. A response time of the first engine group is faster than a response time of the second engine group when the output power of the machine is below the predetermined power output threshold.

Abstract: A plurality of generator sets, or gensets, each including an electrical generator operatively associated with a prime mover, are arranged in parallel to generate electrical power for an isolated electrical load. To account for fuel efficiency, emissions considerations or similar consideration associated with the prime movers, an asymmetric load sharing method may be used to regulate operation of the plurality of gensets. A control strategy is configured to allocated real power demands of the electrical load among the plurality of gensets in accordance with the asymmetric load sharing method. The control strategy may account for the reactive power portions of the electrical load in addition to the real power portions.

Abstract: A system and method for charging a plug-in electric vehicle are disclosed. The system includes a plug-in electric vehicle having a frame, a rechargeable battery pack, a vehicle inlet, a positioning module, and a first communication module; and a battery charging station having a plurality of connectors, an actuation mechanism, and a second communication module. The battery charging station is in operative communication with the PEV, can anticipate an arrival of the PEV, and can ready a connector corresponding to the PEV's vehicle inlet type. The method includes monitoring one or more characterising parameters of a PEV, determining that the PEV needs charging, routing the PEV to a battery charging station, transmitting forecasting information and an identity of the PEV to the battery charging station, and charging the PEV at the battery charging station.

Abstract: A system for limiting power to a plurality of on-line consumers includes an operating characteristic sensor associated with each of a plurality of prime movers and a controller. The controller is configured to determine a maximum torque capability of each of the plurality of prime movers, determine the available electrical power response of each of the plurality of generators, determine a total available electrical power response, and determine a total maximum power demand. The controller then compares the total available electrical power response to the total maximum power demand, and upon the total maximum power demand exceeding the total available electrical power response, limits power to the plurality of on-line consumers to no more than the total available electrical power response.
