Contribution of Distributed Generations in Microgrid to Reduction of LFC Capacity in Utility Grid
Recently, a number of researches on microgrids have been conducted. It is expected that, in the future, the microgrid can keep the power balance between supply and demand in its own area without any support from the utility grid. In addition, more microgrids will be introduced owing to the development of the related technologies. This paper proposes a method to reduce the load frequency control (LFC) capacity of thermal units in the utility grid by using the surplus power of the distributed generations (DGs) in the microgrid. In this paper, it is assumed that a large number of the combined heat and power (CHP) generators are installed as the controllable generators in the microgrid. In addition to the thermal units, a portion of the LFC signal specified by the dispatching ratio is sent to the microgrid. The proposed method is validated on the small-scale IEEJ East 30-machine system.
