摘要
Due to the inherently distributed nature of generating units, distributed control strategies are widely employed in ac autonomous microgrids. However, since a complementary communication network is still needed for exchanging information among neighboring generators, active power deviations may be deteriorated under different communication disturbances. In this paper, a distributed control based on pinning consensus algorithm is developed in ac autonomous microgrids, which is capable of canceling the influences of disturbances. First, the deficiency of the traditional pinning-consensus-based distributed control is revealed given the impacts of disturbances (e.g., noise, malicious attacks, etc.) at the communication network. In order to eliminate the influence of communication disturbances, a state observer is involved, and the estimates obtained from the state observer are utilized to suppress the impacts in power sharing. By using this proposed method, the proportional active power sharing is achieved. In particular, the unnecessary disconnection of influenced communication links among distributed generators (DGs) can also be avoided when the proposed control is used. Simulation results verify the effectiveness of the proposed method.
