A plurality of generators can be connected in parallel to a common electrical bus. Each generator has a controller that regulates the voltage and frequency of the electricity being produced. Before a given generator connects to the electrical bus, its controller senses whether electricity is present on the bus and if not, the connection is made. Otherwise, the controller synchronizes the electricity being produced to the electricity is present on the bus before the connection occurs. The controller in each generator may also implement a load sharing function which ensures that the plurality of generators equitably share in providing the total amount of power demanded by the loads. The load sharing can be accomplished by controlling the generators to operate a substantially identical percentages of their individual maximum power generation capacity.
