Problems solved by technology

In other words, the grid typically does not know when a consumer is turned on and how much power the consumer is consuming, nor does the consumer know how much power the grid can supply
As a result, if many consumers start operating at the same time, the aggregated load on the grid may exceed the grid's operating capacity, which can lead to higher operating costs or even grid failure

Embodiment Construction

[0039] power grid

[0040] exist figure 1 Among them, the grid 110 is a power supply network that provides power to the power consumption devices 125 , 126 , 127 , 135 , 136 , 137 , 145 , 146 and 147 in the grid 110 . In the present invention, the grid 110 may be a smart grid that can directly or indirectly provide its status information (such as working capacity, pricing strategy, etc.) to the connected smart meters 120 , 130 and 140 .

[0041] In order to describe the concept of the present invention, it is necessary to clarify terms used in this specification. Referring to FIG. 2 , the horizontal coordinate represents the time of day, and the vertical coordinate represents the energy provided by the grid 110 during the time of day. The aggregated energy provided by the grid 110 at a particular time of day is referred to as load (at Figure 2a shown as a solid line). The load can be divided into non-transferable loads (in image 3 shown as dotted line in a) and transf...

Abstract

The present invention generally relates to load control in an electrical grid (110). Operation of a power consuming device (125) in the electrical grid (110) is controlled. An ideal shiftable load of the electrical grid (110) is received or accessed. A probability distribution of starting time of the power consuming device (125) is determined based on the ideal shiftable load of the electrical grid (110). Then a starting time for the operation of the power consuming device (125) is determined in accordance with the probability distribution of starting time. An instruction is then sent to cause the power consuming device (125) to be started at the starting time.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to the applicant's Australian provisional application 2013900285 filed with Australian National ICT on 30 January 2013, the contents of which are hereby incorporated by reference. technical field [0003] The present invention generally relates to load control in smart grids. Aspects of the invention include computer-implemented methods, software, and computer systems for controlling the operation of power consuming devices. Background technique [0004] In a traditional grid, the grid rarely interacts with the power-consuming devices it serves. In other words, the grid typically doesn't know when a consumer is turned on and how much power the consumer is consuming, nor does the consumer know how much power the grid can supply. As a result, if many power consumers start operating at the same time, the aggregate load of the grid may exceed the operating capacity of the grid, which may ...
