1. An apparatus, comprising:
an integrated electrical power unit includes a battery storage plant, a controller, a power conversion and conditioning module,
wherein the power conversion and conditioning module includes i) electrical components configured to perform an electrical power conversion of alternating current (AC) power supplied from a main AC power source to direct current (DC) power provided to the battery storage plant, ii) electrical components configured to perform an electrical power conversion of DC power from the battery storage plant into AC power supplied out of the power conversion and conditioning module, and iii) electrical components configured to perform an electrical power conditioning of the AC power supplied from the power conversion and conditioning module to be an uninterruptible supply of regulated and conditioned AC power remaining within a set voltage level and frequency range to eliminate swings in voltage amplitude, frequency, or both voltage amplitude and frequency that are outside the set voltage level and frequency range of the regulated and conditioned AC power even in response to the AC power supplied from the main AC power source features swings in at least one of voltage level and frequency outside the set voltage level and frequency range of the regulated and conditioned AC power,
wherein the power conversion and conditioning module is configured to supply the uninterruptible supply of regulated and conditioned AC power to remain within the set voltage level and frequency range to electrical equipment loads downstream of the integrated electrical power unit,
wherein the power conversion and conditioning module is electrically coupled to a magnetic coupling choke to form a line reactor that provides a prescribed amount of impedance to allow the controller time to change of a state of a set of circuit breakers to isolate the main AC power from the electrical equipment loads so as to operate as an emergency backup source to compensate for and eliminate at least one or more of i) surges, ii) transients, and iii) harmonics issues to a voltage level, frequency, and phase of an AC voltage associated with the AC power coming from the main AC power source from reaching and affecting the electrical equipment loads,
wherein the power conversion and conditioning module is further configured to supply a portion of the regulated and conditioned AC power supplied to the electrical equipment loads in order to stay within the set voltage level and frequency range from the power conversion and conditioning module by compensating for any deficiencies from the AC power coming from and still being supplied by the main AC power source to maintain a combined AC power supplied to the electrical equipment loads to remain within the set voltage level and frequency range of the regulated and conditioned AC power.
