Control system for maintaining preferred battery levels in a microgrid

A system for controlling a battery state-of-energy within a micro-grid, the system comprising:

• an energy generation (EG) system;
• a battery system coupled to the EG system, the battery system having a state-of-energy;
• and
• a controller coupled to the EG system and the battery system, the controller configured to:
• monitor a state-of-energy of the battery system;
• set a target charge value and a target discharge value based on the state-of-energy;
• and
• control the power generation of the EG system to meet a load demand on the system and attempt to control charging and discharging of the battery system within the target charge value and the target discharge value to adjust the state-of-energy to a desired range.

A method comprising:

• receiving, by a processor, state-of-energy data from a battery system coupled to an energy generation (EG) system and an electrical load;
• determining, by the processor, which operational state of a plurality of operational states the battery system is operating in based on the state-of-energy data;
• determining, by the processor, a preferred target charge value and target discharge value of the functional state;
• and
• controlling, by the processor, a power generation of the EG system based on a load demand of the electrical load and the preferred charge and discharge values.
