LONG-TERM OPTIMAL OPERATION OF MICRO-GRID WITH MICRO-HYDROPOWER AND ENERGY STORAGE
Micro-grid can either be interconnected with power grid or be disconnected and operate independently.Although there are many micro-hydro units in China,most of them are connected to the feeder of 10kV or below.So when a shortage of power occurs,and the feeder has to be pulled out,micro-hydro units connected to the feeder will fail to supply power,resulting in lack of electricity and a large amount of surplus water.This paper proposes to solve this problem by establishing micro-grids containing micro-hydropower,feeder loads,and a certain amount of storage facilities.In this paper,a long-term optimal operation model of micro-grid with micro-hydropower and energy storage devices is established.The type and capacity of storage facilities in the micro-grid are discussed.Finally the numerical example based on local feeder load and micro hydro units data shows validity and effectiveness of the proposed model.
