1. A method of controlling production flow in a well, the method comprising:
controlling a flow of formation fluids into a production conduit at each of a plurality of locations in a well;
generating electrical power at each location in response to a portion of the flow into the production conduit at that location;
collectively supplying the electrical power generated at the plurality of locations to a power grid;
independently adjusting the flow of the formation fluids into the production conduit at each location using the electrical power from the power grid;
closing the flow at a selected one of the locations such that insufficient electrical power is generated at that location to reopen flow at that location; and
selectively reopening flow at that location using electrical power from the power grid supplied by the electrical power generated at one or more other of the locations.
