Synergistic operation of distributed compensators based on the conservative power theory

This paper proposes a synergistic operation of distributed compensators. By a synergistic operation, a part of a distribution system can behave as a single element. Two distributed compensators are responsible for achieving the operation. The grid may demand three requirements from the element: cancellation of the input current, operation under unit power factor and injection of active power into the grid. These requirements are independent of each other and the loads inside the element are kept fed all the time. The conservative power theory is used to establish the references of the compensators. Experimental results show the efficacy of the proposed operation.
