ELECTRICAL ENERGY STORAGE SYSTEM WITH CONSTANT STATE-OF CHARGE FREQUENCY RESPONSE OPTIMIZATION

摘要

A frequency response optimization system includes a battery configured to store and discharge electric power, a power inverter configured to control an amount of the electric power stored or discharged from the battery, and a frequency response controller. The frequency response controller includes receiving a regulation signal from an incentive provider, determining statistics of the regulation signal, using the statistics of the regulation signal to generate a frequency response midpoint, and using the frequency response midpoint to determine optimal battery power setpoints for the power inverter. The power inverter is configured to use the optimal battery power setpoints to control the amount of the electric power stored or discharged from the battery.

1. A frequency response optimization system comprising:
a battery configured to store and discharge electric power; a power inverter configured to control an amount of the electric power stored or discharged from the battery at each of a plurality of time steps during a frequency response period; and a frequency response controller configured to:
receive a regulation signal from an incentive provider,determine statistics of the regulation signal,use the statistics of the regulation signal to generate a frequency response midpoint that maintains the battery at a constant state-of-charge (SOC) at a beginning and an end of the frequency response period while participating in a frequency response program, anduse the frequency response midpoint to determine optimal battery power setpoints for the power inverter; wherein the power inverter is configured to use the optimal battery power setpoints to control the amount of the electric power stored or discharged from the battery.
