Abstract
A system and method for controlling the distribution of energy from a plurality of energy resources to a load. The system includes an energy system controller to control the distribution of energy to an electric load provided by a plurality of energy resources. The energy resources include dispatchable sources of energy such as diesel generators and combined heat and power generators; renewable sources of energy including photo-voltaic cells, wind turbines, and geothermal sources; and storage resources such as electrochemical batteries or pumped hydro reserves.
Claims22
An energy control system configured to control the transmission of energy to an electrical load comprising:
- a renewable energy resource;
- a stored energy resource;
- a memory configured to store program instructions;
- and
- an energy system controller operably coupled to the renewable energy resource, to the stored energy resource, and to the memory, the energy system controller configured to execute the stored program instructions to:
- predict (i) an energy requirement of the electrical load over a first time horizon that extends for a first time duration and (ii) an energy generation of the renewable energy resource over the first time horizon;
- generate (i) an optimally planned power profile for the renewable energy resource over the first time horizon based on the predicted energy requirement and the predicted energy generation and (ii) an optimally planned power profile for the stored energy resource over the first time horizon based on the predicted energy requirement and the predicted energy generation;
- determine (i) an energy requirement error value by determining a difference between the predicted energy requirement and an actual energy requirement of the electrical load over a second time horizon that extends for a second time duration that is less than the first time duration of the first time horizon, and (ii) an energy generation error value by determining a difference between the predicted energy generation and an actual energy generation of the renewable energy resource over the second time horizon;
- and
- control (i) a throttling of the renewable energy resource based on the planned power profile for the renewable energy resource, the energy requirement error value, and the energy generation error value, and (ii) a charging and discharging of the stored energy resource based on the planned power profile for the stored energy resource, the energy requirement error value, and the energy generation error value.
