    摘要: A method for compensating self-induced voltage variations includes computing a first reactive power value (Q
    1 ), obtaining a voltage value at a point of interconnection (POI) between at least one power source and a power grid, comparing the voltage value with one or more pre-defined voltage limits, computing at least one compensation factor (CF) corresponding to at least one portion of the first reactive power value (Q
    1 ) based on an output of the comparison between the voltage value and the one or more pre-defined voltage limits, computing a second reactive power value (Q
    2 ) as a function of the at least one portion of the first reactive power value (Q
    1 ) and the at least one CF, generating a reactive power compensation command based on the computed second reactive power value (Q
    2 ), and transmitting the reactive power compensation command to a power converter.

    摘要: A power distribution system for providing a desired value of voltage regulation is presented. The system includes at least one power source, at least one sink, a distribution feeder configured to couple the at least one power source to the at least one sink. The system includes a plurality of modular voltage regulation units coupled to the distribution feeder, where each of the plurality of modular voltage regulation units includes a transformer including a primary winding having a first end and a second end and a secondary winding having a first end and a second end; and at least one switch coupled to the primary winding of the transformer, where the first end of the secondary winding is coupled to at least one of the first and second ends of the primary winding via the at least one switch. A method of operating a power distribution system is also presented.

    摘要: An electric power system (500) includes an OLTC transformer (550) including a plurality of primary (554) and secondary windings (556) inductively coupled to each other. The electric power system includes at least one on-load tap changer (600) coupled to at least one of the primary and secondary windings that is selectively configurable to regulate the portion of the primary and secondary windings inductively coupled to each other. The electric power system also includes a plurality of buses (2-6) coupled to the transformer and are positioned downstream therefrom. The electric power system further includes at least one processor (115) coupled to the tap changer configured to regulate a voltage bandwidth of the tap changer as a function of estimated voltage values of at least one bus as estimated based on a priori values of power/current transmitted through each bus. The a priori values are substantially based on measured power/current transmission through the on-load tap changer.
