Abstract

A Dispatch Planner (DP) is a component in an Energy System Controller that controls the operation of energy resources interconnected into one energy system to provide optimal energy management for a customer. In one embodiment, the energy storage system includes an electric load, dispatchable sources of energy such as an electrical grid, diesel generators, combined heat and power generators; renewable sources of energy such as photo-voltaic cells and wind turbines; and stored energy resources such as electrochemical batteries or pumped hydro reserves.

Claims

1. A method of controlling energy generation and distribution comprising:

receiving with a controller first prediction data corresponding to available power generated from a renewable energy resource over a predetermined first time period and second prediction data corresponding to power demand for at least one load over the predetermined first time period;

generating with the controller a first constraint model corresponding to power generation capacity of the renewable energy resource over the predetermined first time period with reference to the first prediction data;

generating with the controller a second constraint model corresponding to power demand of the at least one load over the predetermined first time period with reference to the second prediction data;

generating with the controller a first plurality of power control commands with reference to the first constraint model and the second constraint model, the first plurality of power control commands being generated to control operation of the renewable energy resource within constraints in the first constraint model to supply power to the at least one load within constraints in the second constraint model over the predetermined first time period; and

operating with the controller the renewable energy resource with reference to the first plurality of power control commands to adjust a level of power output from the renewable energy resource within a first plurality of constraints in the first constraint model to provide power to the at least one load within a second plurality of constraints in the second constraint model.

2. The method of claim 1, further comprising:

generating with the controller a third constraint model corresponding to power generation from a non-renewable energy resource;

generating with the controller the first plurality of power control commands to generate first portion of the power for the at least one load with the renewable energy resource;

generating with the controller a second plurality of power control commands for the non-renewable energy resource to generate a second portion of the power for the at least one load with the non-renewable energy resource; and

3. The method of claim 2, the generation of the third constraint model further comprising:

generating with the controller the third constraint model with a predetermined load range for the non-renewable energy resource to operate the non-renewable energy resource continuously without deactivating the non-renewable energy resource or operating the non-renewable energy resource at a maximum capacity during the predetermined first time period.

4. The method of claim 1 further comprising:

receiving with the controller the second prediction data for the at least one load including prediction data for power demand of a deferrable load;

identifying with the controller a time deadline during the predetermined first time period for delivery of power to the deferrable load;

identifying with the controller a second time period prior during which the renewable energy resource is predicted to generate power with an available power level that is above a predicted demand level of the at least one load; and

generating with the controller the first plurality of power control commands to operate the renewable energy resource to generate power for at a level that is greater than the predicted demand level during the second time period to provide power to the energy storage resource.
