Coordinating independent distributed generators

Developers of distributed generator schemes often wish to increase the size of their generators, in order to make their projects more economically attractive. This work reported the coordination of the operation of independent distributed generators connected to the same circuit, so as to maximise the amount of electrical energy they deliver without exceeding the power limit of that circuit. An Aggregator, owned by the generators, schedules the generators that can be dispatched in times of reduced output of the other generation. The coordination leads to an additional income from the surplus of electrical energy that is able to be produced. The Aggregator runs a cooperative game with transferable utility to allocate this amount, considering the electrical power produced and the type of each generator. The results of a numerical example showed that all generators have an economic incentive to operate in a coordinated manner.
