Abstract:
A method of operating an electrical feeder (4) permits the electrical feeder voltage to be maintained at the minimum voltage within a voltage range based upon dynamic grouping together of electrical generators (16A, 16B, 16C, 16D) on the electrical feeder with demand response loads on the electrical feeder. A method of assessing the proper operation of a voltage control device (12A, 12B, 12C, 12D) on the electrical feeder involves detecting a number of properties of the electrical power in the electrical feeder both prior to and subsequent to a change in an operational parameter of a voltage control device. An expected effect upon the electrical feeder of one or more distributed generators is filtered from this in order to determine a net effect of the voltage control device itself on the electrical feeder. Based upon the detected net effect and a predicted baseline effect for the voltage control device, it can be determined whether the voltage control device is functioning properly.

Abstract:
A controller (4) and method are usable to control the provision of electrical power from a local electrical network (8) to a power grid (12). If it is determined (106) that changes in the power grid voltage are correlated with the provision of power to the power grid, the power that is being provided to the power grid is manipulated so that the rate of change of the wattage that is provided to the power grid does not exceed a predetermined ramp rate. Such a manipulation is accomplished by adjusting (122) an operational parameter of one or more electrical loads that are connected with the local electrical network.
