System and method for conserving energy resources in a power-distribution network

A method for controlling a power compensator including a compensation capacitor and an inverter, the method comprising:

• determining a target output current for the power compensator to provide from the power compensator to a power-distribution network;
• determining a capacitor compensation current provided by the compensation capacitor;
• determining a difference between the target output current and the capacitor compensation current;
• and
• controlling the inverter to provide an inverter current to the power-distribution network, the inverter current being a difference between the target output current and the capacitor compensation current.

At least one non-transitory computer-readable medium storing thereon sequences of computer-executable instructions for controlling a power compensator including a compensation capacitor and an inverter, the sequences of computer-executable instructions including instructions that instruct at least one processor to:

• determine a target output current for the power compensator to provide from the power compensator to a power-distribution network;
• determine a capacitor compensation current provided by the compensation capacitor;
• determine a difference between the target output current and the capacitor compensation current;
• and
• control the inverter to provide an inverter current to the power-distribution network, the inverter current being a difference between the target output current and the capacitor compensation current.

A power compensator comprising:

• a power interface configured to be coupled to a power-distribution network;
• an inverter coupled to the power interface;
• a ripple filter coupled to the inverter;
• a compensation inductor coupled to the power interface;
• and
• at least one controller configured to
• determine a target output current for the power compensator to provide to the power-distribution network via the power interface,
• determine an inductor compensation current provided by the compensation inductor, and
• control the inverter to provide an inverter current to the power interface, the inverter current being a difference between the target output current and the inductor compensation current.
