Switching control for parallel aggregates responsive to demand - are typically for boiler burners or compressors of cooling system

The switching control for similar, parallel aggregates causes a cyclic sequence to be used for switching ON each aggregate in response to a start signal, with a second cyclic sequence used for switching OFF each aggregate in response to a reset signal, with a counter for the operating time associated with each, its max. range being less than that of the total operating interval. The switching control responds to a counter reaching its max. value, to cause the aggregate to be switched OFF and places this aggregate at the end of the switching ON sequence. This counter is reset to start upon subsequent switching ON of the aggregate.

Constant speed control system for wind power generator - uses generator frequency or voltage or vane position to control switching cycle (NL 10.9.80)

The operating system for an arrangement for converting wind power into electrical power, uses an electric generator which supplies a number of outlets by means of a switching system. The switching in and out operations are carried out serially at selected intervals which may be initiated by control signals corresponding to vane positions so as to ensure a constant speed of rotation. The generator frequency can be used as a base to control the switching cycle. Alternatively, the generator voltage or the vane position can be used. The frequency operates a frequency to voltage converter which generates a control signal proportional to frequency or voltage between given limits.

Demand-side management method and system

A method of, or system for, operating a plurality of distributed energy resources (DERs) electrically connected to a power supply network.

The DERs are then operated according to the best scored plan. Predicted voltage drops and network load factors may be used in the score calculations.

Grid stabilising system

The invention provides control of an electric load receiving power from a grid. The frequency of the grid is detected and used to determine a stress level on the grid. A high frequency detection is indicative of too little a load for the electrical power being supplied to the grid and, therefore, a low stress condition. A high stress condition may exist if there is too much load for the power being supplied to the grid. Adjustment of the power consumption of the load is prevented if the high and/or low stress states is determined. If a critical high or low stress condition is determined, the load is either prevented from consuming power completely or the load is set to a maximum power consumption state, respectively. The benefits of the invention are increased if the device is combined with a load controller which operates to control power consumption based on grid frequency and a variable, which, for the particular load, is to be kept within controlled limits.

The variable time delay (tn) is a function of a state of the network (20), for example its frequency (t) and/or its voltage amplitude (V). Optionally, the device (30) is a battery charger, for example for use with a rechargeable electric vehicle. Beneficially, the smart responsive load (10) is supplied with electrical power from a population of micro-generation devices (500) operable to provide supply network response.

If a change is detected, the processor is configured to identify an appliance event corresponding to the change, obtain information relating to the projected utility consumption of the appliance for an upcoming time period, update a projected utility consumption of the premises based on the obtained information, determine whether any projected stored and/or generated utility amount at the premises is sufficient for the projected utility consumption of the premises, and, if not sufficient, cause the device to output a request to receive a utility amount from one or more other premises connected to the premises via a communication network.

Highly Flexible Electrical Distribution Grid Edge Energy Manager and Router

An electrical distribution grid energy management and router device, or GER device, may be installed in a distribution grid, and route power from power supply to one or more power consumers. The GER devices described herein may provide platforms to add one or more features to a distribution transformer, provide additional features and benefits to both the utility company and end consumer, and may serve as a platform for providing other features, such as communications services, local and remote management, and intelligence to components of the distribution grid. A GER device may include sensors to measure electrical properties of incoming and outgoing power, and may include an electrical circuit layer having a central DC power stage. A GER device may also include a communications platform for one or more communication devices to communicate with a utility, power consumers, other electrical devices/parties, and/or other GER devices to form a micro-grid.

Energy management server, energy management method, and program

According to an embodiment, management server includes estimator, scheduler, acquisition unit, monitoring unit, receiver and setting unit. Estimator calculates estimated value of energy demand in building with electric appliance. Scheduler creates schedule of appliance based on estimated value. Acquisition unit acquires actual value of energy demand. Monitoring unit monitors error between estimated value and actual value. Receiver receives DR signal containing information which prompts suppression of energy consumption in a designated period. Setting unit sets threshold. Estimator recalculates estimated value if error is equal or more than threshold. Scheduler reforms schedule based on the recalculated estimated value.

Smart-Grid Adaptive Power Management Method and System With Power Factor Optimization and Total Harmonic Distortion Reduction

A method and system of power factor optimization and total harmonic distortion are provided under the premise of efficient power management and distribution on an electrical grid. The method and system include a novel optimization technique based on a novel current profiling methodology enabling real-time power management with power factor correction as a function of the optimization. The optimization can be performed under dynamic current constraints. When deployed on an electrical grid, the method and system can provide a new technique for power management targeting an efficiency of the electrical grid. The method and system can thus provide for reduced costs of energy production and reduced carbon emissions into the atmosphere.
