    Abstract

    This paper presents a new dynamic control strategy to control active and reactive power in distributed-generation integrated distribution systems. The distribution system comprises several microgrids that have a local energy-management system. The proposed method improves voltage and frequency profile in the distribution system by applying control action ahead of time. Moreover, the proposed method can operate with minimal topology information of the microgrid as it directly balances generation and consumption of power in the microgrid. Another advantage of the proposed method is that it can use fast and expensive sources, such as gas turbine generators, to balance power during transients and let slower and cheaper generators gradually take over after the transients are damped out. The proposed method can be implemented online. Therefore, it can efficiently use the time-variant reactive capabilities of the DGs to compensate reactive power needs of the system.
