Abstract: A power control device for use in an AC power grid for regulating an electrical power a load that is supplied by the AC power grid consumes. The power control device has a frequency sensing functional block for detecting a deviation of the grid frequency from a nominal grid frequency and a logic functional block for performing a load adjustment process during which the power the load consumption is reduced. The load adjustment process is based at least in part on the variation of the frequency of the AC power grid. The load adjustment process is design such that for a plurality of power control devices the individual response produce a grid-wide effect that compensates imbalance between power generation and load in fashion that may reduce unwanted distortion in the AC power grid, such as flicker.

Abstract: The method is carried out for continuously producing a liquefied methane gas (LMG) from a pressurized mixed methane gas feed stream. It is particularly well adapted for use in relatively small LMG distributed production plant, for instance those ranging from 400 to 15,000 MT per year, and/or when the mixed methane gas feed stream has a wide range of nitrogen-content proportions, including nitrogen being substantially absent. The proposed concept can also be very useful in the design of medium-scale and/or large-size plants, including ones where the nitrogen content always remains above a certain threshold. The methods and arrangements proposed herein can mitigate losses of methane gas when venting nitrogen, for instance in the atmosphere.

Abstract: A system for regulating electrical energy transfer over a pathway including a DC link (16, 18, 20) is provided. The system is configured for computing a rate of electrical energy flow through the DC link at least in part on a basis of a state of balance between power generation and a load determined from frequency measurement (32, 34) and for adjusting the rate of electrical energy flow through the DC link. An electrical vehicle charger is provided that includes a power input for connection to an AC power distribution network and a power output for connection to an electric vehicle, and is configured for determining a rate of electrical energy flow through the power output by using as a factor a state of balance between power generation and load in an AC power distribution network to which the power input connects. A method for regulating electrical energy transfer over a pathway including a DC link is also provided.

Abstract: Systems and methods for cooling an Integrated Circuit (IC) are provided. In one embodiment, the system includes a vessel for holding a coolant in a liquid phase, where the IC is at least in part thermally coupled to the coolant to transfer heat generated by the IC to the coolant. The system also includes a controller for periodically increasing a heat flux supplied by the IC to the coolant followed by a reduction of the heat flux supplied by the IC to the coolant. Methods for controlling the operational parameters of the IC to periodically increasing and then decreasing the heat flux supplied by the IC to the coolant are also provided. A sensor may be used to sense a state of phase change of the coolant and which generates a signal that the controller uses to adjust the heat flux supplied by the IC.

Abstract: A system for cooling a CPU. The system has a tank for holding dielectric coolant in a liquid phase. The CPU is immersed in the coolant. A cover closes the tank. Electric pathways that convey data to/from the CPU traverse the cover. The electric pathways allow the CPU to exchange data with an external device. In this fashion, the CPU can perform data processing functions while being immersed in dielectric coolant.

Abstract: A power control device for regulating the power that a load consumes on the basis of the AC supply frequency. The system includes decision logic that responds to a frequency deviation to implement a power regulation strategy. The power regulation strategy includes a power compensation phase during which the electrical power that the load consumes is adjusted (reduced or increased) to balance the load on the grid. The power regulation strategy also includes a power restoration phase during which the power to the load is restored (either increased or decreased). The rate at which the power is adjusted during the power compensation phase is higher than the rate at which the power is restored during the power restoration phase.

Abstract: The system is provided for generating a mixed methane gas feed stream using at least one source of biogas and an alternate source of methane gas. The system includes a biogas subsystem, a control device for the methane gas from the at least one alternate source of methane gas, and a vertically-extending gas mixing vessel.

The proposed concept is particularly well adapted for situations where an uninterrupted and relatively constant input of methane gas is required to ensure an optimum operation of, for instance, a LMG production plant.

Abstract: The gas flare system includes a vertical flare stack having an opened top end and a bottom floor wall. A weatherproof protective hood arrangement prevents rain and snow from entering through the opened top end. The gas flare system also includes a burner arrangement provided through the bottom floor wall. The burner arrangement receives a waste gas stream from a waste gas circuit and also primary air. Secondary air orifices around the burner supply secondary air coming from a plenum housing located directly underneath the bottom floor wall. The gas flare system can destroy the flammable gas in the waste gas stream with a combustion efficiency of more than 99% under almost any operating conditions. It can start automatically and operate efficiently without any supervision under any possible atmospheric conditions. A method of destroying a flammable gas in a waste gas stream is also disclosed.

Abstract: A power control device for controlling electrical power transferred between an AC power grid and a load or between the AC power grid and an auxiliary power source. For example, the power control device may be configured to monitor an electrical characteristic of electrical energy supplied by the AC power grid to the load and to adjust a consumption of the electrical energy by the load when the electrical characteristic indicates that the AC power grid is no longer in a state of balance. As another example, the power control device may be configured to control an electrical energy injection process during which an injection of electrical energy from the auxiliary power source into the AC power grid is increased in relation to a detected rate of deviation of the AC power grid frequency.

Abstract: A method for managing the operation of an AC power distribution network to which connect a plurality of electric vehicles, at random times and at random locations to receive electrical energy for charging. The AC power distribution network is characterized by a dynamic state of balance between power generation and load, and it has an operating reserve which is a supplemental power generation capacity available to the AC power distribution network. The method includes the step of forecasting a power-supply contribution that would be available to the AC power distribution network from the electric vehicles connected to the power distribution network in the event the AC power distribution network experiences a state of imbalance resulting from a power-generation deficit. The method further includes adjusting the magnitude of the operating reserve on the basis of the forecasting.
