Abstract
A method and system for controlling the transfer of electrical power between a first electrical network and a second electrical network is disclosed. The method includes receiving at the second electrical network pricing information from the first electrical network, the pricing information associated with the supply of electrical power between the first electrical network and the second electrical network, and modifying a demand characteristic of the second electrical network based on the pricing information.
Claims26
A method for controlling the transfer of electrical power between a first electrical network and at least first and second end-user electrical networks, wherein the first electrical network is an electrically interconnected utility-scale grid under the control of a market operator supplied by at least a first power generation source and a second power generation source, and comprising a transmission and/or distribution interconnection network operable to supply power from the electrically interconnected utility-scale grid to the at least first and second end-user electrical networks, comprising:
- determining by the first power generation source a first temporal power pricing forecast based on the future generation and supply capacity of the first power generation source to the electrically interconnected utility-scale grid;
- determining by the second power generation source a second temporal power pricing forecast based on the future generation and supply capacity of the second power generation source to the electrically interconnected utility-scale grid;
- determining by the electrically interconnected utility-scale grid pricing information associated with the future supply of electrical power from the electrically interconnected utility-scale grid based in part on the first and second temporal power pricing forecasts;
- operably linking a selected end-user electrical network from the first and second end-user electrical networks to the first power generation source by providing the first temporal power pricing forecast covering a forecast time period to the selected end-user electrical network;
- and
- synchronizing a demand characteristic of the selected end-user electrical network to the first power generation source based on the first temporal power pricing forecast for the forecast time period.
The method of 7, wherein the first temporal power pricing forecast includes a time dependent feed-in tariff forecast for the supply of electrical power from the selected end-user electrical network to the first power generation source.
An electrical power switching system comprising:
- a first electrical network, wherein the first electrical network is an electrically interconnected utility-scale grid under the control of a market operator supplied by at least a first power generation source and a second power generation source, and comprising a transmission and/or distribution interconnection network operable to supply power from the electrically interconnected utility-scale grid to at least first and second end-user electrical networks, wherein
- the first power generation source provides a first temporal power pricing forecast based on the future generation and supply capacity of the first power generation source to the electrically interconnected utility-scale grid,
- the second power generation source provides a second temporal power pricing forecast based on the future generation and supply capacity of the second power generation source to the electrically interconnected utility-scale grid, and
- the electrically interconnected utility-scale grid provides the future supply of electrical power from the electrically interconnected utility-scale grid based in part on the first and second temporal power pricing forecasts;
- a selected end-sure electrical network from the first and second end-user electrical networks operably linked to the first power generation source by providing the first temporal power pricing forecast covering a forecast time period to the selected end-user electrical network;
- at least one power measurement device for providing a real-time measurement of the flow of electrical power between the electrically interconnected utility-scale grid and the selected end-user electrical network;
- a power flow modulation device operable to modulate the electrical power consumption between the electrically interconnected utility-scale grid and at least a portion of the selected end-user electrical network;
- and
- a controller receiving as inputs the output of the at least one power measurement device and the first temporal pricing forecast from the first power generation source and operable to control the power flow modulation device with time dependent programmable events to synchronize a demand characteristic of the selected end-user electrical network to the first power generation source based on the first temporal power pricing forecast for a forecast period.
