Frequency response control system with clipping parameter determination

A method for controlling an amount of electric power stored or discharged from a battery in a frequency response control system, the method comprising:

• operating a high level controller to determine values of clipping parameters;
• providing the values of the clipping parameters from the high level controller to a low level controller;
• operating the low level controller to modify battery power setpoints using the values of the clipping parameters;
• and
• using the modified battery power setpoints to control the amount of the electric power stored or discharged from the battery.

A multi-building management system comprising:

• building equipment that operate to affect a variable state or condition within one or more buildings;
• a battery configured to store and discharge electric power for use in powering at least one of the building equipment or the one or more buildings;
• 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 comprising:
• a high level controller configured to determine values of clipping parameters;
• and
• a low level controller configured to use the values of the clipping parameters to modify battery power setpoints;
• wherein the power inverter is configured to use the modified battery power setpoints to control the amount of the electric power stored or discharged from the battery.
