First Claim
Patent Images
1. A method for controlling the flow of energy in an electrical power grid, comprising:
- a. shedding an optimal amount of energy demand for a user of the grid based on a set of possible values for actual energy procurement costs in the real-time market (RTM) and on a set of possible values for an actual non-moveable energy demand of the user;
b. shifting an optimal amount of energy demand for the user to a time when cheaper energy procurement costs may be obtained, said shifting based on a set of possible values for actual energy procurement costs in the real-time market (RTM) and on a set of possible values for actual non-moveable energy demand of the user; and
c. repeating the shedding and shifting steps until a convergence of respective total energy procurement costs of shedding and shifting is achieved.

11. A control system for an electrical power network that minimizes the costs of providing electricity to users in the network, comprising a processor that sheds a first amount of electricity demand for a respective user;
- time-shifts a second amount of electricity demand for the respective user; and
repeats shedding and time-shifting until a convergence is achieved, said shedding and time-shifting each using a set of possible values for actual electricity procurement costs in the real-time market (RTM) and a set of possible values for actual non-moveable electricity demand of the respective user - View Dependent Claims (12, 13, 14, 15)
- time-shifts a second amount of electricity demand for the respective user; and
