Abstract: Presented herein are systems, devices, and methods for providing electrical power. A system can include a power source configured to provide at least a subset of electrical power to an electrical bus. The system can include an inverter coupled with the power source and the electrical bus, the inverter configured to convey the electrical power between at least the power source and the electrical bus. The system can include a voltage controller coupled with the inverter. The voltage controller can be configured to generate, responsive to an initiation of synchronization between the inverter and the electrical bus, an inverter command to enable phase locked loop (PLL) control on the electrical power. The voltage controller can be configured to modify, responsive to a completion of the synchronization, the inverter command to disable the PLL control on the electrical power.

Abstract: Presented herein are systems, devices, and methods for parallel control. A device can receive a first power signal corresponding to electrical power convey via an electrical bus, the first power signal comprising a power and at least one of a first voltage or a first frequency. The device can identify a change in the first power signal greater than a threshold. The device can generate, from the first power signal, a second power signal using at least one of a second voltage or a second frequency associated with the change, wherein the second voltage or the second frequency is different from the first voltage or the first frequency, respectively.

A device may monitor for a transition in a first power signal corresponding to electrical power conveyed between an inverter and an electric bus. The device may identify, responsive to detecting the transition in the first power signal, a frequency in accordance with the transition in the first power signal and a frequency droop slope and a voltage in accordance with the transition and an amplitude droop slope. The device may modify the first power signal using the frequency and the voltage to generate a second power signal to maintain the power. The device may convey the electrical power between the inverter and the electric bus.

Abstract: Presented herein are systems, devices, and methods for inverter control. The device may include a computer-readable medium having instructions stored thereon.

The at least one processor may determine that a synchronization between the inverter and the electrical bus is complete. The at least one processor may disengage, responsive to the determination that the synchronization is complete, the PLL control on the electrical power conveyed between the inverter and the electrical bus.

Abstract: An energy storage system (EMS) for mobile and stationary applications includes multiple battery circuits connected in parallel via bidirectional DC-DC converters and managed by centralized or distributed control. Each circuit comprises one or more electrochemical storage elements, and the EMS regulates current flow based on system data indicative of state-of-charge (SOC), state-of-health (SOH), temperature, and chemistry. The EMS performs active balancing by adjusting current commands to equalize SOC across circuits and isolates faulty or degraded modules when necessary. In vehicle applications, the EMS manages power flow between traction batteries, electric drive units, and low-voltage systems, supporting propulsion, regenerative braking, and accessory loads. In stationary systems, the EMS integrates with generators, renewable sources, or grid-tied inverters to coordinate energy delivery, provide backup power, and optimize battery usage.
