摘要：
A two-level optimization model of thermal unit commitment is built for the hybrid wind- thermal power system with given capacity of ESS(Energy Storage System), which uses ESS to eliminate the uncertainty of wind power as much as possible and to provide partial power generation reserve. Its upper layer is to minimize the cost of thermal unit commitment and its lower layer is to maximize the benefits from the spatio-temporal translation of electric energy and the reserve provided by ESS as well as the uncertainty elimination degree. The effect of system frequency regulation and the performances of AGC (Automatic Generation Control ) and non-AGC units are considered in the model. Based on the principle of decomposition and coordination, the model is solved by the alternating iterations between upper and lower layers to obtain the charge/discharge schedule and regulation range of ESS as well as the thermal unit commitment scheme, showing that the power generation reserve of thermal units is reduced and the ability to cope with system uncertainty improved. The validity of the proposed model and method is verified with a 10-unit system. © 2017, Electric Power Automation Equipment Press. All right reserved.
