Motivated by the fact that the location(s) and structural properties of thepinning node(s) affect the algebraic connectivity of a network with respect tothe reference value and thereby, its dynamic performance, this paper studiesthe application of intelligent single and multiple pinning of distributedcooperative secondary control of distributed generators (DGs) in islandedmicrogrid operation. It is shown that the intelligent selection of a pinningset based on the degree of connectivity and distance of leader DG(s) from therest of the network improves the transient performance for microgrid voltageand frequency regulation. The efficacy of the distributed control strategybased on the proposed algorithms is illustrated via numerical resultssimulating typical scenarios for a variety of microgrid configurations.
